Different applications require TFT-LCD Modules with different performance parameters. Handheld devices for example require TFT-LCDs with high resolution and wide viewing angles, whereas automotive applications require displays, which must operate over an extremely wide temperature range. A number of parameters must be considered when choosing a display for a particular application. These include, but are not limited to the parameters described below:
Viewing Angle: ZBOE offers a range of technologies from TN to IPS/ADS technologies. For many applications, where wide viewing angles are not necessary, TN technology is employed to provide the viewer a crisp, sharp image when viewing the display. If very wide viewing angle is required either ADS or IPS technology can be employed to provide the view with a display which can be viewed at viewing angles up to 89° all view.
Brightness: ZBOE offers a series of standard displays with a range of brightnesses up to 1,000cd/m². Many indoor displays require brightness up to 300nits, but for outdoor use in bright sunshine up to 1000cd/m² may be required. Furthermore customization of the display backlight can be easily done, too. If there is a standard display module, which size, resolution and dimensions match the customer’s performance, then the backlight can be modified to meet the customers preferred brightness.
Temperature Range: For extreme temperature ranges, especially for automotive temperatures, ZBOE can offer TFT-LCD modules, which operate up to +85degC and can be stored to -40degC.
Interface: As displays move to higher resolutions, high speed interfaces are now becoming common place. While ZBOE continues to offer RGB and SPI interfaces for low resolution displays, too, we offer MIPI interface solutions covering resolutions up to WUXGA resolutions for small-medium sized displays and EPD interfaces for even higher resolution displays.
Touch Technology and Bonding: ZBOE offers a wide range of touch technologies, including in-cell/on-cell touch, CTP with CG, PCAP and RTP. In-cell/On-cell touch is mostly used in consumer electronics devices. For non-consumer applications, CTP is the most common technology and can be either bonded using optical bonding or air-gap bonding. Optical bonding improves sunlight readability as well as viewing angle performance. ZBOE offers both optical bonding as well as air-gap bonding.
