We report on a monitor‐sized, thin, dimensionally and thermally stable mini‐LED backlight enabled by a patterned glass diffuser (PGD). Our backlight has a luminance of between 0.9 × and 1.05 × compared to a reference mini‐LED backlight using a thick diffuser plate, while providing a better local dimming control and comparable zone and panel luminance uniformity and color uniformity. The PGD technology can reduce the number of LEDs.

We proposed a novel lighting system with optical lens of the car head-up display (HUD) and the camera CCD estimation method of the projection virtual image. This novel optical lens lighting system shows up to 0.8 million nits BLU brightness with 3M DBEF4, 15° full viewing angle and better uniformity. Besides, we set up a new measurement method to estimate projection virtual image performance and the tolerance with human factor test is within 4 %. Finally, we have demonstrated AUO HUD combined with the optical lens lighting system and displayed average 4.5 X projection image during 1418 mm distance from the driver. And the virtual image brightness within 50 * 130 mm 2 eye-box is average 8900 nits.

We report our progress on a monitor‐sized, dimensionally and thermally stable mini‐LED backlight enabled by a patterned glass diffuser (PGD). Our backlight uses 5,000+ fewer mini‐LEDs per monitor — 4/9 times that in a reference mini‐LED backlight relying on a thicker diffuser plate, while it is thinner and achieves similar uniformity and luminance compared to the reference mini‐LED backlight.

We propose a novel borderless design for dual displays by using novel BLU and innovative light deflecting film above the display panel. Compared to the previous design, this new structure provides much better borderless image quality, thinner module, and higher brightness. We also set up a simulation model to optimize the borderless performance. Finally, we demonstrate great borderless effect on 5.8 inch dual displays and successfully eliminate the 3mm border width from A-A to A-A visually.

In this paper, we successfully develop a new optical touch which is highly integrated with current structure of TFT-LCD display. The advantages are high touch resolution, no active force, free object touch, low cost and easy integration with panel. Besides, we have set up a simulation system to predict and optimize the touch performance. In addition, the signal to noise ratio (SNR) is measured around 21 by 4" mockup sample. A superb touch display can be achieved in the near future.
