Pixel circuit and display device

Abstract

The invention discloses a pixel circuit and a display device, belonging to the display field. The pixel circuit includes: a first inverter module, whose input end is connected to the first node, and whose output end is connected to the second node; a second inverter module, whose input end is connected to the second node, and whose output end is connected to the third node. a node; a switch module respectively connected to the first node and the third node, configured to disconnect the electrical connection between the first node and the third node when the first scan signal is at an active level; An adjustment module connected to at least one of the first node and the second node, configured to adjust the first node and the second node according to an adjustment control signal when the first scan signal is at an active level. The level at at least one of the nodes. The invention helps to avoid the abnormal output signal of the latch inside the pixel, enhances the working stability of the pixel circuit, and improves the performance of related display products.

Description

technical field [0001] The invention relates to the display field, in particular to a pixel circuit and a display device. Background technique [0002] In a traditional active matrix display device, regardless of the display mode of a dynamic picture or a static picture, a driver is used to write data into pixels. In this case, when displaying a static image, the driver will repeatedly write the same data into the pixels. For this situation, a memory can be provided in each pixel, so that when a static picture is displayed, the data memorized in the memory can be written into the pixel instead of the driving of the driver, so as to reduce power consumption. In order to meet the application requirements of high PPI (Pixels Per Inch, the number of pixels per inch), low power consumption, and low cost of the display device, a latch circuit composed of transistors is set inside the pixel to realize the function of the memory. However, in practical applications, this type of la...

Problems solved by technology

However, in practical applications, this type of latch is prone to abnormal output signals when the output level is reversed, making the display state of the pixel circuit unstable, resulting in abnormalities such as noise or blurred screens, and seriously affecting the performance of display products.
