This article introduces the solutions to improve LCD HDR performance. Backlight solutions including passive, active driving mini LED backlight and halo effects are studied. High cell transmittance and enhanced TFT device reliability for high brightness are discussed. Furthermore, the vivid image and high contrast can be kept in high ambient light by applying AUO A.R.T. technology.

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.

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.
