Problems solved by technology

Due to the small area of ​​the under-screen camera, the 2T1C pixel circuit has little impact on the display screen, but the current 2T1C pixel circuit operating voltage is not within the normal data voltage range given by the drive circuit, so the under-screen camera area is equipped with a traditional 2T1C pixel circuit Not advisable

Abstract

The invention provides a pixel circuit and a display panel. The display panel includes a pixel circuit; the pixel circuit includes a data line, a scan line, several levels of 2T1C circuits, a step-down circuit, and a reset circuit; the data lines are used to transmit source data signals; the scan lines are used to transmit scan signals; several levels Each input terminal of the 2T1C circuit is connected to the scanning line; the input terminal of the step-down circuit is connected to the data line, and its output terminal is connected to the other input terminal of each 2T1C circuit; the reset circuit is connected to the Input terminal of the step-down circuit. The present invention realizes the effect of improving light transmittance by changing the circuit structure of the camera area under the screen.

Description

technical field [0001] The invention relates to the display field, in particular to a pixel circuit and a display panel. Background technique [0002] With the continuous development of science and technology, people have higher and higher requirements for display devices, and the development of display screen technology is also advancing by leaps and bounds. Nowadays, the design of "full screen" has become the mainstream of the times, and all screen suppliers are focusing on the research and development of full-screen products with a high screen-to-body ratio. Increasing the screen-to-body ratio of a display screen has become a product development trend. [0003] At present, many solutions to increase the screen-to-body ratio on the market usually design the front camera on the outside of the display screen, and use special-shaped cutting design to avoid a certain size of the display screen to accommodate the front camera. No matter how the cutting design changes, it is ver...
