Technical Field
[0001] The utility model relates to the technical field of display module detection devices, in particular to an integrated thermal-sensitive testing device for a display module. Background Art
[0002] Display screens have a huge market. Currently, many display screens are equipped with thermal devices and have thermal functions. They can automatically adjust the temperature of the display screen and adjust the temperature compensation parameters according to the ambient temperature to ensure that the display screen has a good display effect in low or high temperature environments. For this type of display screen, we need to test the thermal effect to ensure that the thermal effect is ok. However, the conventional test baseboard does not have an integrated thermal effect detection function. An external thermal test driver board is required to detect the thermal effect of the product. Therefore, an additional detection process and detection device are required during the detection, which will not only affect the detection efficiency, but also increase the detection cost.
