Problems solved by technology

[0004] In view of this, the embodiments of the present invention provide a display driving circuit, a display panel and electronic equipment, the main purpose of which is to solve the problem that the driving circuits in the existing display panel all have positive voltage and positive current in the same direction, which generates positive voltage and positive current in the panel. Coupling effects and external electromagnetic interference will immediately cause electromagnetic interference to the touch panel on the upper layer of the display panel, which is prone to noise, signal-to-noise ratio degradation, and even poor touch control

Abstract

The invention discloses a display driving circuit, and relates to the technical field of display equipment. According to the main technical scheme, the display driving circuit comprises a power module, light-emitting assemblies and a control module, and the power module provides positive and negative driving voltages; the plurality of light-emitting assemblies are arranged in a matrix manner, theplurality of light-emitting assemblies are all electrically connected with the power supply module, and the driving voltage polarities of the light-emitting assemblies in adjacent rows / adjacent columns are opposite; the control module is electrically connected with the power module and is used for controlling the power module to provide a positive / negative driving voltage for the light-emitting assemblies in the corresponding rows / columns; and the control module receives an image signal, is electrically connected with the plurality of light-emitting assemblies and is used for providing an equal gate voltage / source voltage for the light-emitting assemblies in the same row / column according to the image signal.

Description

technical field [0001] The present invention relates to the technical field of display equipment, in particular to a display driving circuit, a display panel and electronic equipment. Background technique [0002] With the progress of the times, organic light-emitting diode (Organic Light-Emitting Diode, OLED) display technology is more and more favored by people. [0003] Existing OLED display panels are all driven by positive pressure. Full positive voltage drive means that the drive circuits in the display panel are all positive voltage and positive current in the same direction, which produces coupling effects in the panel and external electromagnetic interference, and then Electromagnetic interference will be generated on the touch panel on the upper layer of the display panel, which may cause noise, decrease in signal-to-noise ratio, and even poor touch control. Contents of the invention [0004] In view of this, the embodiments of the present invention provide a di...
