Problems solved by technology

[0004] Although using the above-mentioned patents and setting the appropriate start-up time and shutdown time can produce an effect similar to the instantaneous interruption of the input AC power, it is not as good as directly inputting the input AC power of the instantaneous interruption to the electronic device under test. , can more accurately detect whether the electronic device can still work normally after the input AC power supply is interrupted and switched on, which is not disclosed in the above patent

Abstract

The invention discloses a detecting device of a liquid crystal display and a method thereof, belonging to the field of detection technology. The detecting device executes a plurality of detection stages for the liquid crystal display in sequence according to detection parameters set by users. Each detection stage sequentially comprises the following steps of: turning on and turning off a power supply many times, and detecting whether the display picture of the liquid crystal display and the control function are normal or not. Each round of turning on and turning off the power supply includes a step of turning on the power supply once to provide power for the liquid crystal display and a step of turning off the power supply once to stop providing power to the liquid crystal display. The frequency and time for turning on and turning off the power supply in each detection stage are the same, while the duty ratios of turning on and turning off the power supply are different. When the display picture of the liquid crystal display or the control function is abnormal, the liquid crystal display does not pass the detection. When all the detection stages are executed and the display picture of the liquid crystal display or the control function is normal, the liquid crystal display passes the detection.

Description

technical field [0001] The invention relates to the technical field of detection, and in particular to a liquid crystal display detection device and method. Background technique [0002] After the electronic device is manufactured, it must perform and pass various tests before it can be sold out of the factory. Taking liquid crystal display as an example, before leaving the factory and selling, it must be checked whether it can still work normally after the input AC power is cut off and on, such as whether the display screen is normal, whether the screen menu will pop up after pressing the button on the control panel or the remote control ( On-Screen Display, referred to as OSD) to provide the control function of the liquid crystal display to the user. [0003] Taiwan Patent No. 564354 discloses a control device and method for automatic testing, which includes first inputting the parameters of the start-up time, shutdown time, and switch times into the detection device, and...
