Lighting control system board, detection method and lighting detection device

Abstract

The invention discloses a lighting control system board, a detection method and a lighting detection device. The lighting control system board comprises a main control module, a conversion control module and a voltage generation module. The main control module outputs a plurality of voltage generation signals to the voltage generation module, and controls the voltage generation module to determine voltage values of corresponding lighting voltages. The main control module generates enable signals respectively corresponding to the voltage generation signals via the conversion control module and outputs the enable signals to the voltage generation module, so that the voltage generation module outputs the corresponding lighting voltages having the determined voltage values under the control of effective potentials of the enable signals. The generated enable signals have invalid potentials during the period from start to end of power-on of the lighting control system board, so that the voltage generation module has no output under the control of the invalid potentials of the enable signals, the lighting voltages with uncontrollable timing sequences can be prevented from being output when the lighting control system board is powered on, and therefore the lighting voltages output to a display panel can be effectively controlled, and stability of display panel test can be improved.

Description

technical field [0001] The invention relates to the field of display panel testing, in particular to a lighting control system board, a detection method and a lighting detection device. Background technique [0002] In the production and preparation process of the display panel, the lighting test is generally carried out on the display panel through the lighting detection device to detect whether there are bad spots (for example: bright spots or dark spots) on the display panel, and the lighting detection device is generally controlled by the lighting control system board. working. Contents of the invention [0003] Embodiments of the present invention provide a lighting control system board, a detection method, and a lighting detection device, which are used to solve the problem of outputting to the display panel due to the EN terminal of the programmable circuit being at a high potential when the lighting detection device is powered on in the prior art.

Problems solved by technology

[0003] Embodiments of the present invention provide a lighting control system board, a detection method, and a lighting detection device, which are used to solve the problem of outputting to the display panel due to the EN terminal of the programmable circuit being at a high potential when the lighting detection device is powered on in the prior art. The lighting voltage is uncontrollable, which causes the current input to the display panel to be too large, causing the display panel to be damaged and not to light up.
