Title:
LIGHT UP CONTROL SYSTEM BOARD, DETECTION METHOD, AND LIGHT UP DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/029490
Kind Code:
A1
Abstract:
A light up control system board, which is suitable for a detection method for a system board as well as a light up detection device comprising a system board; the system board comprises: a main control module (10), a control transfer module (20) and a voltage generation module (30); the main control module (10) outputs a plurality of voltage generation signals so as to control the voltage generation module (30) to determine a voltage value of a corresponding light up voltage; by means of the control transfer module (20), generating enabling signals corresponding to each voltage generating signal and outputting the same to the voltage generating module (30); the enabling signals starting power up in the system board, and having invalid potential during a time duration used until power up is complete; the voltage generation module (3) being output-free under the control of the invalid potential of the enabling signals, and outputting a light up voltage to a display panel (40) under the control of a valid potential of the enabling signals. The system board prevents the output of a light up voltage which a time sequence cannot control during power up.
