Embodiment 1

[0031] Such as figure 1 As shown, the electrostatic protection structure 1 includes a central processing unit 11, a display screen 12, and an electrostatic attenuation resistor 13. The display screen 12 is connected to the central processing unit 11, and the electrostatic attenuation resistance 13 has an input terminal and an output terminal, and the central processing unit 11 is connected to The input terminal and the output terminal are connected to the display screen 12. Among them, the display screen 12 includes but is not limited to a liquid crystal touch screen and a capacitive touch screen.

[0032] In other words, an electrostatic attenuation resistor 13 is added between the display screen 12 and the central processing unit 11 of the terminal, so that when static electricity is introduced by the display screen 12, it will be attenuated by the electrostatic attenuation resistor 13 and then enter the central processing unit 11. As a result, the electrostatic interference re...

Embodiment 2

[0037] On the basis of the basic electrostatic protection structure 1 shown in the first embodiment, the electrostatic protection structure 1 shown in the first embodiment can be further refined.

[0038] Such as figure 2 As shown, the number of processor interfaces 121 is multiple, and each processor interface 121 is connected to a corresponding output interface on the central processing unit 11, that is, connected to a corresponding pin on the central processing unit 11, wherein at least one processing An electrostatic attenuation resistor 13 is provided between the interface 121 and the central processing unit 11.

[0039] In other words, the multiple processor interfaces 121 are respectively connected to multiple output interfaces on the central processing unit 11 through corresponding paths, and at least one path is provided with an electrostatic attenuation resistor 13, which can achieve the electrostatic discharge of the central processing unit 11. The purpose of total atte...

Embodiment 3

[0043] On the basis of the first and second embodiments above, due to the addition of the electrostatic attenuation resistor 13, the voltage output of the central processing unit 11 will decrease when it reaches the display screen 12. In order to compensate for the reduced voltage output, the central processing unit 11 can be Set multiple output drive gears, and each output drive gear has a corresponding output drive size. In this way, when it is necessary to compensate for the reduced voltage output, a higher gear can be selected to obtain a larger output drive.

Abstract

The invention provides an electrostatic protection structure and a terminal. The electrostatic protection structure comprises a central processing unit, a display screen and an electrostatic attenuation resistor, wherein the display screen is connected to the central processing unit; the electrostatic attenuation resistor has an input end and an output end; the central processing unit is connected to the input end; and the output end is connected to the display screen. According to the technical scheme of the invention, when static electricity is introduced by the display screen, the static electricity is attenuated by the electrostatic attenuation resistor and enters the central processing unit, so that the electrostatic interference born by the central processing unit is greatly reduced, the electrostatic protection ability of the terminal is enhanced, the influence of the electrostatic interference on normal operation of the terminal is reduced, and the user experience is improved.

Description

[0001] 【Technical Field】 [0002] The invention relates to the technical field of terminals, in particular to an electrostatic protection structure and a terminal. [0003] 【Background technique】 [0004] At present, terminals such as mobile phones use display screens as a medium for user operations to achieve touch control, which brings great convenience to user operations. [0005] However, the display screen will accumulate charge and cause ESD (Electro-Static Discharge) interference, and ESD interference is likely to cause the terminal to crash and affect the normal operation of the terminal. [0006] Therefore, how to reduce the influence of ESD interference on the terminal has become a technical problem to be solved urgently. [0007] [Content of the invention] [0008] The embodiments of the present invention provide an electrostatic protection structure and a terminal, aiming to solve the technical problem that ESD interference affects the normal operation of the terminal in the re...
