Abstract

The invention discloses a pixel circuit which comprises a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor, a sixth transistor, a seventh transistor, an eighth transistor, a first capacitor and a second capacitor. According to the pixel circuit, the problem that critical voltage compensation is insufficient can be solved, and the situation that the display quality is reduced due to leakage current in a low-frame-rate mode is avoided.

Description

technical field [0001] The present invention relates to a pixel circuit, in particular to a pixel circuit arranged on a flexible printed circuit board to reduce cost and improve display quality. Background technique [0002] In the application of display devices, wearable display devices are products that attract considerable attention from consumers. Whether it is a head-mounted device, or a variety of smart bracelets, watches, etc., different sizes and resolutions will be set according to the needs. monitor. These display devices include a plurality of pixel circuits in the display area, and these pixel circuits are driven by driving circuit chips arranged in the peripheral area, and then control each pixel in the display area to emit light to display images. [0003] In the existing design, these driving circuit chips are mostly disposed on a chip on film, and are connected to a multiplexer circuit to transmit driving signals to each pixel circuit respectively. However,...
