P‐168: Extremely Low‐Power Consumption Design for LCD In‐Cell Touch Panel

In‐cell touch technology, as an important medium of human‐ machine interaction, is widely used in products such as mobile phones, tablets, notebooks, and so on. However, the addition of the vertical touch line (TP) in in‐cell touch pixels leads to a decrease in pixel aperture rate and uneven display of sub‐pixels with or without TP lines. In view of the characteristics of different sizes and resolutions of pixels, this paper innovatively re‐arranges the layout of data line and TP line, such as placing the data line in the middle of sub‐pixel, S‐shaped data line routing, and dual TFT for one sub‐pixel designs, to increase the overall transmittance of pixels while avoiding uneven display. Through the above‐mentioned design to increase the transmittance, the panel power consumption can be reduced by 3% to 10%.
