Problems solved by technology

It is difficult to adjust the compensation capacitance during use by simply adding a capacitor for compensation. Once the fluctuation of the actual process causes the compensation capacitance to deviate from the ideal value, it is difficult to achieve the ideal compensation effect.

Abstract

Embodiments of the present disclosure provide a signal line capacitance compensation circuit and a display panel. The signal line capacitance compensation circuit includes: a plurality of signal lines; at least one control line, a compensation capacitance is provided between the control line and at least one signal line in the plurality of signal lines; and a signal source, the signal source configured to send a charging signal to one or more of the at least one control line, the charging signal is used to connect the one or more control lines receiving the charging signal with the at least one signal The compensation capacitor between the lines is charged.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to a signal line capacitance compensation circuit and a display panel. Background technique [0002] With the development of full screens, special-shaped full screens with notch designs (such as "notch" screens) are increasingly adopted by mobile phone manufacturers. This special-shaped full screen is conducive to obtaining a higher screen-to-body ratio, and the notch design in the display can reserve design space for components such as the front camera. However, this notch design will cause differences between the pixel gates on both sides of the notch and the normal pixel gates. This difference is mainly manifested in the difference in capacitive coupling of the gate lines, so it is necessary to add compensation capacitors to the pixel gates on both sides of the notch to compensate for the difference in capacitive coupling. It is difficult to adjust the compensation ca...
