Extremely Low-Power Consumption Design for LCD In-Cell Touch Panel

Description:

Incell 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 incell-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%.
