[0002] At present, the test method of display quality of digital image source is visual inspection, which is not easy to observe because of the small display area of digital image source, and the brightness of digital image source is too high to be observed by eyes
In actual use, the digital image source displays its own display on the panel through projection. At this time, the display brightness of the panel will also be weakened to within the range of the normal display module, and the problems of the display quality of the digital image source will be displayed on the panel. It is clear at a glance, but the cost of the entire projection system is not low, and it is difficult to equip a projection system for inspection, which is too expensive

The invention discloses an image source test device and a test method thereof. The image source test device comprises a support plate, two side plates, a magnifying glass and a gray glass placement device; the two side plates are arranged on the support plate And the two side plates are arranged in parallel; the magnifying glass is detachably connected to the two side plates, the gray glass placement device can be used to place the gray glass, and the plane where the gray glass is located is the same as that of the gray glass The plane where the support plate is located has an included angle; the support plate is also provided with a fixing mechanism for fixing the image source to be measured, and the magnifying glass and the fixing mechanism are respectively arranged on both sides of the gray glass placement device. The cost of the image source testing device is low and it is convenient for testers to observe the display quality of the image source to be tested.
Description
technical field [0001] The invention relates to a digital image source test, in particular to an image source test device and a test method thereof. Background technique [0002] At present, the test method of display quality of digital image sources is visual inspection, which is not easy to observe because of the small display area of digital image sources. In addition, the brightness of digital image sources is too high to be observed by eyes. In actual use, the digital image source displays its own display on the panel through projection. At this time, the display brightness of the panel will also be weakened to within the range of the normal display module, and the problems of the display quality of the digital image source will be displayed on the panel. It is clear at a glance, but the cost of the entire projection system is not low, and it is difficult to equip a projection system specially for inspection, which is too expensive. [0003] Therefore, it is an urgen...
