Abstract

A pixel circuit, its driving method, and a display device. The pixel circuit includes a first switch subcircuit, a partition driver chip, and a plurality of light-emitting elements, wherein: the first switch subcircuit is connected to a scanning line, a data line, and a first node connection, used to write the data voltage signal of the data line into the first node under the control of the scan line; The corresponding driving time of each light-emitting element is determined according to the data voltage signal, and the light-emitting element is driven to emit light by using the data voltage signal within the corresponding driving time. This application realizes the active site selection drive through the first switch sub-circuit and the partition driver chip, which effectively reduces the number of glass-based wiring, greatly reduces the difficulty of the side wiring process, and reduces the driving power of the overall display module. Consumption and driving costs, greatly improving the competitive advantage of the product.

Description

technical field [0001] The present application relates to but not limited to the field of display technology, and in particular relates to a pixel circuit, a driving method thereof, and a display device. Background technique [0002] As a new generation of display technology, the sub-millimeter light-emitting diode (Mini Light Emitting Diode, Mini LED) has low power consumption, high brightness, ultra-high resolution and color saturation, fast response, ultra-power saving, long life, and high efficiency. advantage. [0003] The Mini LED display device is usually driven by a Passive Matrix (PM) driving method, and the row driver chip and the column driver chip can be connected to each sub-pixel by multiplexing (MUX). like figure 1 As shown, taking the display resolution of 80*90 as an example, if the 1:90MUX method is used, each column needs a channel (CH) signal, and each row needs two MUX signals (the two MUX signals are used for the R sub-pixel and GB sub-pixel), a tota...
