Abstract

The invention discloses a self-luminous pixel circuit. The self-luminous pixel circuit comprises a driving module and a light-emitting module which are arranged between a first variable potential anda second variable potential and connected with each other, wherein the driving module controls the magnitude of current flowing through the light-emitting module according to a time sequence. According to the self-luminous pixel circuit provided by the invention, a higher brightness adjustment range can be switched through the first variable potential and the second variable potential, so that thegray scale number of the self-luminous pixel circuit can be further improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to the field of self-luminous display technology, and in particular to a self-luminous pixel circuit and a display panel. Background technique [0002] For a long time, display panels have been developing towards thinner, lighter and more flexible. Organic electroluminescence, quantum dot electroluminescence, and micro-electroluminescence self-luminous display panels have natural advantages in these aspects. The light-emitting device with self-luminous display has a positive correlation between the luminous brightness and the applied voltage and current. [0003] In the conventional technical solution, the self-illuminating pixel circuit applied to the above-mentioned self-illuminating display panel has a small luminous brightness range, resulting in a low gray scale, which cannot meet the market demand for further increasing the gray scale.
