Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0032] In the structure of the existing display panel, the display panel includes a display area and a non-display area; in the display area, scanning lines and data lines are intersected to define a sub-pixel area, and sub-pixels are arranged in the sub-pixel area; in the non-display area, there are The driving circuit includes a scanning driving circuit and a data driving circuit. The scanning driving circuit is usually also called a shift register circuit, and the data driving circuit is usually called a multipl...

Abstract

The embodiment of the invention discloses a driving method of a display panel, a display driving device and electronic equipment. The driving method comprises the steps of obtaining a to-be-displayedimage; according to the to-be-displayed image, providing a display signal for the sub-pixel by utilizing the scanning line and the data line; displaying the to-be-displayed image according to the display signal; wherein the display signals comprise grid opening signals and data signals, the grid opening signals are loaded to the scanning lines in one frame of scanning period, and the correspondingdata signals are loaded to the data lines in sequence; wherein the durations of the at least two charging gaps in one frame of to-be-displayed picture are different; wherein the charging gap is a time difference value between an initial write-in moment of the (i + 1) th data signal and an end write-in moment of the ith data signal; i is a positive integer. According to the technical scheme, the duration of the at least two charging gaps is set to be unequal, so that the inherent periodicity of the data signals can be destroyed, the electromagnetic interference can be reduced, and the influence on other vehicle-mounted electronic products when the display panel is applied to a vehicle-mounted display screen can be reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving method of a display panel, a display driving device and electronic equipment. Background technique [0002] With the development of display technology, liquid crystal display (Liquid Crystal Display, LCD) panels and organic light emitting diode (Organic Light Emitting Diode, OLED) display panels have gradually become the two mainstream display panels in the display field, and LCD panels and OLED display panels are widely used Applied to computers, mobile phones, wearable devices, vehicles and other devices or scenes that can integrate display functions known to those skilled in the art. [0003] Usually, the operation of an electronic product will cause interference to other surrounding electronic products. This interference can be called Electromagnetic Interference (EMI). The performance of the electronic product affected by the electromagnetic interference i...
