Problems solved by technology

[0004] With the progress of the times, full high definition (Full High Definition, referred to as FHD) display gradually occupies a dominant position, the number of pixels of the full high definition display increases, and the grid lines and data lines between pixels increase exponentially; and due to the need to ensure a certain transparency Over rate, the line width of the gate line and the data line becomes thinner, and the light utilization rate is low, resulting in low turn-on current Ion of the thin film transistor, increased power consumption, and slow response speed, and further scans caused by insufficient charging of display panel products may occur. The phenomenon of blackening at the end

Abstract

The invention belongs to the field of display technology, and in particular relates to a display panel and a display device. The display panel is divided into a plurality of pixel areas, thin film transistors are arranged in the pixel areas, gate lines and data lines are intersected between adjacent pixel areas, and the pixel areas are in areas corresponding to the thin film transistors, At least part of the region corresponding to the gate line or the region corresponding to the data line is provided with a photodiode, and any of the photodiodes is electrically connected to any one of the gate line or the data line. The display panel utilizes the electrons generated by the photodiode due to light, and reduces the power consumption of the thin film transistor and its display panel and improves the utilization rate of the backlight source through the photo-generated carrier auxiliary driving current, and can also shorten the response time, and can solve the problem of display Panel products are blackened at the scanning end due to insufficient charging, especially suitable for full high-definition liquid crystal display products.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel and a display device. Background technique [0002] With the development of science and technology, flat panel display devices have replaced bulky CRT display devices and are increasingly used in people's daily life. Commonly used flat panel display devices include liquid crystal display devices (Liquid Crystal Display, LCD for short). [0003] The liquid crystal display device includes a backlight, and also includes a color filter substrate, an array substrate, and a liquid crystal layer arranged between them. Each pixel in the array substrate is provided with a thin film transistor (Thin Film Transistor, referred to as TFT) control The deflection of the liquid crystal molecules in the liquid crystal layer allows the light from the backlight to be selectively transmitted, and the transmitted light is colored by the color filter layer in the color fil...
