OLED VS LCD – WHICH IS BETTER?

Microtips Technology / / LCD, OLED

OLED, an acronym for Organic Light Emitting Diode, is often identified as the modern-age display. Many companies are still using LCDs, but the growing demand for OLEDs overshadows the market of LCDs.

Traditional LCDs use CCFL or cold-cathode fluorescent lamps backlight whereas OLEDs use organic material to emit light in different combinations of colors without using any backlight. In LCDs, the light emitted by the LED backlight passes through a layer of crystal material.

In this blog post, we shall compare OLEDs and LCDs based on different parameters.

Comparison Between OLED and LCD

  • Brightness

Since LCDs exhibit full-screen brightness with their LED backlights, they get a competitive edge over OLEDs in this parameter. However, in the modern-age displays, brightness is not given much importance in terms of image clarity and light output.

  • Contrast Ratio

The standard contrast ratio of LCDs of computers may value 1000:1, whereas the contrast ratio of LCD TV displays may go around 4000:1. The contrast ratio of the OLED displays can go as high as 1,000,000:1. The more the contrast ratio is, the better your device’s picture quality will be.

The contrast ratio is the difference between the brightest and darkest visual of a display. Since OLEDs have true black where the pixels turn off when they show black color, which is not the case with LCDs, the OLEDs become a better option for contrast and picture quality.

  • Refresh Rates

The number of times a display presents a new image every second is called refresh rate. The OLEDs switch images far faster than LCDs. Today’s OLED displays have a 120Hz refresh rate far more than the 60Hz refresh rate of traditional LCDs. Despite being ahead of LCD, the OLEDs exhibit motion blur, which is a challenge for aspiring electronic equipment manufacturers of today.

  • Power Consumption

Unlike LCDs that always need the backlight to illuminate their pixels, OLEDs use organic material to emit light and create an image. Having true black is another crucial reason why OLEDs consume less power than the contending LCDs. We can say that it is more about the brightness of the image being displayed. The less the light is emitted, the module will consume less energy. It means if we keep the LED backlight of LCDs low, it is possible to make them more energy-efficient than OLEDs.

  • Viewing Angle

Viewing angle is one of the most crucial parameters where OLEDs win over LCDs. If you sit off-axis in front of an LCD, you may not consider the image in its actual appearance as the visuals would fade away, which is not the case with OLED displays.

Conclusion

In all the parameters we have discussed here, OLEDs seem more advantageous. Moreover, OLEDs are easier to manufacture. Many OLED displays are offering bendable, foldable, and rollable OLED displays. From small-scale applications such as smartwatches to large-scale applications such as smartphones and TV displays, OLEDs are finding across more and more use cases.

Microtips Technology, a US-based OLED and LCD module manufacturer, has launched its range of products having the latest capabilities of OLED.

TOUCH PANELS: RESISTIVE VS CAPACITIVE

Microtips Technology / / Touch Panel, Uncategorized

Touch panels are layered screens allowing users to interact with different devices. These touch panels are available in two types based on their formation and applications: Resistive and Capacitive.

Resistive touch panels, also known as RTP, enable single-touch which means it only accepts input given in the form of pressure by one touch of your finger or stylus, a writing utensil. The composition of RTP includes the layers of polyethylene terephthalate (PET) coated with indium-tin-oxide (ITO) and the glass substrate at the top of its structure.

Capacitive touch panel, popularly known as PCAP or PCT or Projected Capacitive Touch Panels, allows multitouch where it takes electrical properties of the human body as the input as multiple points of contact. The composition of PCAP constitutes a projected capacitive touch screen and a flexible printed circuit connecting the touch screen controller laminated by a protective lens.

Market Value

RTPs were used largely before the arrival of PCAPs. However, the applications of RTPs reduced to small-scale applications as smart devices were seeking touch panels that would be of high contrast, more efficient, and multitouch. RTPs are easy to produce and more affordable. Some of the common and well-known applications of RTPs include electrical and mechanical equipment, point-of-sale devices, ATM machines, wearables, and digital cameras.

On the other hand, PCAPs are used in devices with high-performing and clearer screens with increased optical transmissivity and gestures.

Parameter-Based Comparison

PCAPs are dominating the market in all significant factors any aspiring customer would seek in a touch panel today.

Let’s have a quick tabular comparison between the two types of touch panels;

Microtips Technology, a US-based touch panel manufacturer has developed 4,5 & 8 wire resistive, multipurpose PCAPs, integrated touch panels, and film sensor packages. They have kept their touch panel developments waterproof, of precise experience, and responsive to glove and stylus touch. These touch panels are being adjusted in different fluids i.e. PCAPs in OLED screens.

HDMI VS DISPLAY PORT INTERFACE: WHAT IS THE DIFFERENCE?

Microtips Technology / / HDMI

When it comes to digital video transmission, there are two interfaces commonly preferred, namely, High Definition Multimedia Interface (HDMI) and Display Port (DP). These technologies are rapidly taking over conventional analog interfaces like VGA, GRG, S-Video, etc. Because of their popularity, HDMI cable ports and display ports are pitted against each other. However, these technologies serve several specifications that suit various applications. Therefore, the selection of an appropriate video transmission interface becomes complex. To avoid confusion during the selection, one must get to know about HDMI cable ports and display ports. This post discusses HDMI port and display port interfaces followed by a comparison of their specifications in order to help the selection process.

Get Introduced to HDMI and DP

The following pointers will help you understand the difference between HDMI and DP

  • High Definition Multimedia Interface (HDMI)HDMI is a digital video transmission interface. It was first introduced in 2003 by the collective efforts of a few display manufacturers. It is a proprietary medium that enables audio/video signal transmission of compressed or uncompressed digital data between two or more HDMI- compliant devices. HDMI display module works in compliance with high-bandwidth digital copy protection (HDCP) protocol for encrypted audio or video signal transmission.
  • Display Port (DP)Display port is a digital video transmission standard introduced by Video Electronics Standard Association (VESA) in 2006. It was developed for video signal transmission between computers and other display monitors. By using this standard, the operator can connect laptops or PCs to display devices like projectors.Although both of these interfaces are developed and introduced to perform the same task of digital multimedia signal transmission, there are certain factors that help in comparing these two technologies. Let us now compare HDMI cable port and display port interfaces based on different factors.

Comparison between HDMI Cable Port and Display Port Interfaces

HDMI display modules and display port modules are compared to each other on the basis of the following factors.

  • Connectors: The HDMI cables are compatible with five types of HDMI connectors. Out of the five, only three are commonly used. The HDMI connectors are categorized according to the functionality.
    • Type A, HDMI connectors are used for TVs, projectors, etc.
    • Type C, are mini HDMI connectors used for tablets, laptops, etc.
    • Type D, HDMI connectors are micro connectors used for mobile phones and portable devices.
    All these HDMI connectors feature 19 pin construction. Along with these 29 pin HDMI connectors are used for dual-link applications.On the other hand, the display port interface features a 20 pin connector, which is available in two standard sizes. The full-size display port connector is used for computers, and display monitors whereas the mini display port connectors are suitable for small portable video devices.
  • Bandwidth and Resolution: The bandwidth and resolution are the specifications that keep changing across versions. As the technologies keep evolving, the updated versions of HDMI and display port come up with enhanced bandwidth and resolution. Therefore, the comparison must be done with the latest versions only. The latest versions of HDMI and display port feature the same bandwidth of 60Hz for 8K and 120Hz for 4K transmission. However, the HDMI resolution is 720p to 1080p, and the display port has surpassed 1027p to 4320p resolution. Despite the difference in resolutions, the HDMI is implemented in several high-end products from global brands. The resolution of the display port is not adopted by any display manufacturer due to the demand for very high bandwidth to support the resolution.
  • Audio Features: Both HDMI and display port enable transmission of 8 digital audio signals at 12 bit and 192 kHz frequency. However, the HDMI display module features an audio return channel (ARC) that allows the video transmitter and the display unit both to emit audio based on requirements. This helps when the user wants to play display on TV but wants audio from another sound system. The display port does not support ARC which makes the HDMI display module superior in the case of audio units.
  • Transmission Cable Length: Generally, HDMI cables are short due to short distance transmission between a phone and projector, or a video transmitter and a TV. They often are used for up to 2km transmission. However, HDMI signals can transmit over CAT5 or CAT6 cables up to 50 meters, over coax-cable up to 90 meters, and over fiber optics up to 100 meters.On the other hand, the display port cables carry high-resolution signals up to 2 km but further the resolution limits. It can run up to 15 km at low resolution, but it cannot be integrated with Ethernet transmission media as it cannot carry Ethernet data.

Now that the comparison is made, it shall be convenient for you to make a choice between HDMI cable ports and display port interfaces. However, keep in mind that most of the display manufacturers adopt HDMI TFT display interface in their products. Also, the quality of products must be ensured, that is why you must buy from trusted suppliers like Microtips Technology. The company is one of the leading display manufacturers in the US. Their HDMI displays offer a seamless interface and superior display experience.

WHAT MAKES OLED DISPLAYS SUPERIOR TO LED DISPLAYS?

Microtips Technology / / OLED

Today, most industrial and commercial electronic devices are equipped with LED or OLED displays. Even though there seems to be a difference of just an alphabet “O” in both these terms, they are quite different in functionality. LED certainly has ruled the TV industry for decades, but ever since OLED was introduced, it has proven its superiority to users. Not to mention, OLED was introduced as an upgraded version of LED, the better and organic one. This is why both these technologies are pitted against each other for superiority. However, there is no doubt that OLED stands superior to LED but in what terms? What are the factors that make OLED displays superior to LED displays? This post discusses the differences between LED and OLED displays and sheds light on factors that make OLED displays better than LED.

What are LED Displays?

LED displays combine light-emitting diode (LED) technology with flat panel displays. These LED displays are known for their brightness due to the implementation of backlight technology. Basically, these LED displays are manufactured by adding an array of light-emitting diodes at the back of the panel display. These light-emitting diodes cover pixels and offer better brightness. These displays can be used outdoors as well.

Even though LED displays were and are quite popular, the upgraded technology of OLED displays was introduced in the year 2013. OLED is claimed to be a superior technology. Let us discuss what OLED displays are and what makes them special.

What are OLED Displays?

OLED stands for the organic light-emitting diode. It is also known as organic electroluminescent diode technology. In the OLED display panels, an organic emissive electroluminescent layer is added in the front of the OLED display panel. The organic compound layer works in response to the electric current and only emits visible light which is not harmful to human eyes. Since the light emitted by OLED displays is organic, it makes the display as good as the natural light. This factor itself becomes an aspect of the superiority of OLED over the LED. However, OLED has several other benefits to offer over the LED. Let us discuss the benefits of OLED over LED that make it a popular display technology.

Superior Benefits of OLED over an LED

The following are the benefits OLED has to offer over the LED.

  • OLED features organic layers that can be made of plastic or any organic polymer. This makes OLED displays lighter, thinner, and more flexible, as compared to the glass crystal layers in LED displays.
  • The light-emitting layer in OLED features smaller LEDs as they cover pixel by pixel screen area. Therefore, the display setup of OLED displays becomes compact as compared to LED backlight display.
  • Unlike initially launched OLEDs, the modified OLED displays overcome the brightness problem. The modified and advanced OLED displays are actually brighter than LED displays due to thinner organic layers, and color patterning technologies like shadow mask patterning, white + color filter method, etc, which offer a higher conductive and emissive impact.
  • OLED displays consume much lesser power than LEDs, as OLED displays do not feature backlight. The OLED diodes generate and emit light organically, which suffices naturally bright display.
  • OLED displays are more convenient for battery operated video display devices like mobile phones, as less power is consumed by the screen layer.
  • OLED displays offer a wide-angle view of 170 degrees, whereas LED displays block vision due to inherent viewing obstacles.
  • OLED display manufacturers can opt for bulk manufacturing, as the manufacturing pattern of these displays remains compatible with a design for manufacturing and assembly (DFMA).

Now that you are well-literate with the superiority of OLED displays over LED displays, you must be considering buying OLED displays. If yes, then you must buy high-resolution OLED display modules from trusted manufacturers like Microtips Technology. The company is recognized for their expertise in display manufacturing technology since the 1990s. Manufacturing custom OLED displays are certainly one of their popular displays.

Having said that, you get to choose from a large selection of these displays on the OLED Displays page. If you already know the part number, you can use the Microtips Search Assistant to simplify your search. For any assistance, you can always get in touch with the team at Microtips Technology.
