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 herein 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, the drawings only show some but not all structures related to the present invention.

[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, the scanning lines and the data lines are crossed to define a sub-pixel area, and sub-pixels are arranged in the sub-pixel area; in the non-display area, a The drive circuit includes a scan drive circuit and a data drive circuit. The scan drive circuit is also commonly referred to as a shift register circuit, and the data drive circuit is usually referred to as a multiplexing circuit. The sh...

Abstract

The embodiments of the present invention disclose a driving method of a display panel, a display driving device and an electronic device. The driving method includes: acquiring an image to be displayed; using a scan line and a data line to provide a display signal to the sub-pixels according to the image to be displayed; displaying the image to be displayed according to the display signal; wherein the display signal includes a gate turn-on signal and a data signal, and In one frame of scanning period, the gate turn-on signal is loaded on the scan line, and the corresponding data signal is loaded on each data line in turn; in a frame to be displayed, the duration of at least two charging gaps is unequal; the charging gap is the i+1th The time difference between the start writing moment of the first data signal and the end writing moment of the ith data signal; i is a positive integer. In this technical solution, by setting at least two charging gaps with different durations, the inherent periodicity of the data signal can be destroyed, which is beneficial to reducing electromagnetic interference and reducing the impact on other vehicle-mounted electronic products when the display panel is applied as a vehicle-mounted display screen.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a driving method of a display panel, a display driving device and an electronic device. Background technique [0002] With the development of display technology, Liquid Crystal Display (LCD) panels and Organic Light Emitting Diode (OLED) display panels have gradually become the two mainstream display panels in the display field. LCD panels and OLED display panels are widely used. It is applied to devices or scenarios known to those skilled in the art that can integrate display functions, such as computers, mobile phones, wearable devices, and vehicles. [0003] Usually, the work of an electronic product will cause interference to other surrounding electronic products, and the interference may be called electromagnetic interference (Electromagnetic Interference, EMI). The performance of the electronic product subjected to the electromagnetic interference is degraded,...
