Abstract

The invention discloses a testing tool for a display screen of an electronic device. The testing tool is characterized by comprising a base station, a mainboard, a control circuit and a control switch, wherein a containing part is arranged on the base station; the display screen is applied to being arranged in the containing part; one end of the control circuit is connected with the mainboard; theother end of the control circuit is applied to being connected with the display screen; and the control switch is positioned in the containing part and controls on-off of the control circuit. When the display screen is arranged in the containing part, the display screen triggers the control switch to be turned on, and the control circuit is connected; and when the display screen deviates from thecontaining part, the control switch is turned off, and the control circuit is disconnected. According to the testing tool for the display screen of the electronic device disclosed by the invention, the control switch is arranged in the containing part, so that the display screen can be located in a power-off state in the plugging / unplugging process, and the defect that the display screen is damaged due to generated electrical surge is avoided. Moreover, connection and disconnection of the control circuit can be controlled by placing the display screen in the containing part or not, so that the testing tool can achieve an excellent fool-proofing effect.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular, to a test tool for a display screen of an electronic device. Background technique [0002] When the display screen performs detection, the display screen is connected to the main board and powered by the main board. When replacing the display screen to be tested, it is necessary to power off the mainboard, and then turn on the power supply after replacing the display screen. The time is too long and the efficiency is low. If the main board is turned on, the display screen is directly replaced, and the operation of plugging and unplugging the display cable is called "hot swapping". "Hot plugging" will generate electrical surges that will damage the display and circuit IC, that is, burn the screen, so "hot plugging" needs to be prevented from happening. [0003] In the related technology, a heat-resistant plug cable is connected in series between the screen and the ...
