Display device and power driving device

Abstract

The invention provides a display device and a power driving device. The display device comprises a plurality of touch electrode blocks; a driving chip electrically connected with the plurality of touch control electrode blocks and configured to provide a common voltage signal and a touch control driving signal for the touch control electrode blocks. A plurality of display stages and touch stages which are sequentially arranged at intervals are included in a gap between every two adjacent vertical synchronizing signals; in the display stage, the driving chip provides a common voltage signal forthe plurality of touch electrode blocks; in the same touch control stage, the driving chip provides touch control driving signals with the same time sequence for the same column of touch control electrode blocks and provides touch control driving signals with different time sequences for at least two columns of touch control electrode blocks; wherein the touch driving signal comprises a pluralityof touch driving periods, and each touch driving period comprises a touch driving enabling section and a touch driving gap; and the touch driving enabling sections on the two columns of touch electrode blocks provided with the touch driving signals with different time sequences are at least partially overlapped. According to the invention, interference of electromagnetic interference energy on other electronic products is avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device and a power drive device. 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 It is applied to devices (including display devices) or scenes that can integrate display functions known to those skilled in the art, such as computers, mobile phones, wearable devices, and vehicles. [0003] Usually, the operation of an electronic product will cause interference to other surrounding electronic products. The interference may be called Electromagnetic Interference (EMI). The performance of an electronic product subjected to electromagnetic interference is degraded, or even c...

Problems solved by technology

[0003] Usually, the work of electronic products will cause interference to other surrounding electronic products, which can be called electromagnetic interference (Electromagnetic Interference, EMI). The performance of electronic products subject to electromagnetic interference is reduced, and even cannot work normally.
