SYSTEMS AND METHODS FOR COMPENSATING PARASITIC COUPLINGS IN DISPLAY PANELS

摘要

A display panel includes multiple pixel elements for composing an image and a control circuit for accessing each pixel element. The control circuit includes a data line for conducting a luminance signal and a selection line for conducting a selection signal. Each pixel element includes a switch, a display cell, and a compensatory capacitor. The switch is connected to the data line and the selection line, such that the switch can selectively deliver the luminance signal to the display cell. The display cell is configured to adjust its light transmittance in response to the received luminance signal. Being connected to the switch and the display cell, the compensatory capacitor is configured to receive a compensation signal corresponding to a transition of the selection signal and for correcting a parasitic effect at the display cell.

1. A display panel, comprising:
a data line configured to conduct a luminance signal; a liquid crystal display (LCD) cell configured to adjust a light transmittance based on the luminance signal; a selection line configured to conduct a selection signal; a switch coupled to the selection line and the data line, the switch configured to selectively deliver the luminance signal to the LCD cell based on the selection signal; and a capacitor having a first terminal and a second terminal, the first terminal coupled to the LCD cell, the second terminal configured to receive a compensation signal corresponding to a transition of the selection signal.
