A touch control test device and a touch control test method are provided, and the touch control test device includes: a telescopic mechanism with an adjustable length; a touch control component connected to the telescopic mechanism so that the telescopic mechanism is configured to drive the touch control component to tap the touch screen; an acquisition unit configured to acquire an actual detection coordinate point where the touch control component taps the touch screen; a calculation unit configured to calculate a touch control coordinate error between a target coordinate point corresponding to the actual detection coordinate point where the touch control component taps the touch screen and the actual detection coordinate point. The touch test device can achieve a tap touch control test of the touch screen.

Touch-control test apparatus and touch-control test method

A method and a device for testing a rotation performance of a touch display screen are provided. The method includes: determining at least two test positions in a display region of the touch display screen, the at least two test positions including at least one test position located in a central region of the display region and at least one test position located in an edge region of the display region; and testing a rotation performance corresponding to each test position of the at least two test positions.

Method and device for testing rotation performance of touch display screen

A method and a device for testing a rotation performance of a touch display screen are provided. The method comprises: determining at least two test positions in a display region of the touch display screen, the at least two test positions including at least one test position located in a central region of the display region and at least one test position located in an edge region of the display region; and testing a rotation performance corresponding to each test position of the at least two test positions.

A measuring method and a measuring system are used for measuring contrast of a display device, including controlling the display device to display a first image, measuring brightness of a central area of the first image, controlling display device to display a second image, measuring brightness of a central area of the second image, and determining the contrast. Both the first image and the second image have a plurality of areas with different gray scales, the first image includes a maximum gray scale area, and the second image includes a minimum gray scale area.

Measuring method and measuring system thereof

Embodiments of the present invention provide a device and a method for testing transparency effect of a transparent display substrate. The device comprises a transparency identification module, an optical measurement unit and a reference object including two kinds of regions of different colors. The optical measurement unit is able to directly measure brightness of the two kinds of regions of different colors of the reference object to acquire a first brightness difference, and to measure brightness of the two kinds of regions of different colors of the reference object through the transparent display substrate to acquire a second brightness difference. Based on the first brightness difference and the second brightness difference, the transparency identification module calculates identification degree ID of the transparent display substrate according to the equation: where &#x394;Lis the first brightness difference and &#x394;Lis the second brightness difference. Embodiments of the present invention may eliminate the influence of ambient light on the test and increase the test accuracy of the transparent display substrate.
