Problems solved by technology

However, after reading the register operation, some screens cannot return the register value within one line, which may cause abnormal display problems such as screen deviation
It can be seen that the screen reading register method has high requirements on the compatibility of the display screen; moreover, when the screen is in the normal display state, it is necessary to wake up the corresponding thread regularly to do ESD detection, which increases the power consumption of the system

Embodiment Construction

[0027] In order to make the above purpose, features and beneficial effects of the present application more obvious and understandable, specific embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0028] Aiming at the problems of compatibility and system power consumption in the existing method of ESD detection by reading screen registers, the embodiment of this application provides an electrostatic discharge detection processing method and device, in which the DSI is triggered by the DPU to perform ESD detection. The main ESD detection The function is to detect whether the screen is disturbed by static electricity, and restore it to normal through ESD recovery (such as resetting the display, etc.) when it is disturbed. Correspondingly, the DPU receives the ESD detection result returned by the DSI, and when the ESD detection result indicates an abnormality, the DPU triggers an interrupt and performs ESD recove...

Abstract

The invention provides an electrostatic discharge detection processing method and device and terminal equipment. The method comprises the steps that a display processor triggers a display serial interface DSI to carry out ESD detection; receiving an ESD detection result returned by the DSI; and if the ESD detection result indicates that the screen state is abnormal, the display processor triggers interruption, and ESD recovery is carried out. By utilizing the scheme provided by the invention, ESD detection can be effectively carried out on various different display screens, and the power consumption of the system is not increased.

Description

technical field [0001] The present application relates to the field of electrostatic discharge detection, in particular to an electrostatic discharge detection and processing method, device, and terminal equipment. Background technique [0002] With the development of modern technology, the functions of mobile phones and other smart devices with screens gradually tend to be diversified and diversified on their original basis, and have become an indispensable part of people's lives. During the use of electronic products, static electricity may cause abnormal screen display, touch screen failure, and serious crashes. Therefore, eliminating static electricity on equipment is a very important task. [0003] There are usually two methods for detecting static electricity, hardware and software, and the processing on the software is ESD (Electro-Static discharge, electrostatic discharge) detection. Existing relatively mature ESD detection schemes include an external TE (Tearing Ef...
