Vertical gate line in pixel array is one effective method to achieve narrow border LCD. However, this design forms V-shape mura which matches the crossed point positions of the vertical gate line and horizontal gate line , if the pixel array design is not optimized. Through electronic simulation, this paper find out the root cause of the mura is the parasitic capacitance of gate line and data line. The optimum pixel array design is proposed to achieve better image quality of narrow border freeform LCDs for automotive application.

As the rapid growth of LCD market, higher level of image quality is required. Image sticking is a phenomenon that a faint outline of previously displayed image remains visible on the screen as the frame is refreshed and it is an unvarying problem as the birth of LCD display. Furthermore, it has been a critical issue for high standard automotive application. In essence, the image sticking arises from the residual electric field (DC) in liquid crystal which caused by the ordered arrangement of ionic charges or dielectric polarization under the external DC offset voltage. In this paper, we will summarize the mechanism of the the residual DC voltage generation and image sticking. And an optimum Vcom setting method minimizing external DC offset voltage is introduced to improve image sticking.

In this paper a new type of curved TFT LCD which is 15inch 1024×768 integrated ASG solution has been presented. Curved display not only can get realistic visual effect but also fit human eyes better. Panel is fixed by curved backlight to achieve curved display. It is found that image quality of curved display is quite different from flat one. In this paper we discuss brightness uniformity of curved display both white and black image. Based on measurement results we discuss the difference between curved and flat LCD. According to the results,brightness uniformity of LCD should be improved by adjusting cell gap, module design and some IC technology such as local dimming.

To quantify the visual effect of local dimming products by optical parameters, a complete halo testing methodology was proposed. Besides, the fitting curve between Halo and Halo CR (contrast ratio) was also presented. Based on which Halo CR of different local dimming backlights with various zones and LED types can be simulated.
