Abstract

The embodiment of the invention relates to the display field, and discloses a pixel driving circuit and a display device. In some embodiments of the present application, the pixel driving circuit includes: a static random access memory SRAM module and an enabling module, the input terminal of the enabling module is electrically connected to the enabling signal line, and the first output terminal of the enabling module is connected to the first output terminal of the SRAM module. One input end is electrically connected, and the second output end of the enable module is electrically connected to the second input end of the SRAM module; wherein, the enable module is used to control the first output of the enable module according to the enable signal of the enable signal line terminal and the electrical signal output by the second output terminal of the enabling module, so that the SRAM module is in an off state or in a working state. In this implementation, the enable module can turn off the SRAM module under special circumstances.

Description

technical field [0001] Embodiments of the present invention relate to the field of display, and in particular to a pixel driving circuit and a display device. Background technique [0002] Display devices based on OLED / LED are widely used in various fields, such as mobile phones, televisions, and the like. An OLED / LED based display device consists of a plurality of pixel units, each pixel unit includes a driving circuit, and OLEDs or LEDs. The driving circuit includes a Static Random-Access Memory (SRAM) unit. [0003] However, the inventors have found at least the following problems in the prior art: the current driving circuit cannot turn off the SRAM unit of the pixel driving circuit. [0004] It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to those of ordinary skill in t...
