Problems solved by technology

[0002] At present, after the production of mobile phone products, the quality of the mobile phone display screen is observed by human eyes, but there are many places that are difficult to detect by human eyes. For example, when the display screen displays information, the display at the corners is not easy to find. Moreover, it is also a waste of cost to test the display screen by manpower

Embodiment Construction

[0013] refer to figure 1 Shown is the operating environment diagram of the preferred embodiment of the screen testing system of the present invention.

[0014] The screen testing system 11 is applied to testing equipment. In this embodiment, the testing device is a computer 1 , which is used to test the screen 20 of the device under test 2 . The computer 1 includes a processor 10 , a camera unit 12 and a memory 13 . The processor 10 controls the computer 1 to work and run the screen testing system 11 . The photographing unit 12 photographs images, such as a camera. In another embodiment of the present invention, the computer 1 includes multiple camera units 12, so that the screens 20 under test of multiple devices under test 2 can be tested simultaneously. The memory 13 stores the RGB three-primary color values ​​of each pixel of a standard image, wherein the standard image is an image displayed on a good product screen 20 to be tested.

Abstract

The invention provides a screen test system and method. The screen test system shoots a section of video stream, which is displayed by a to-be-tested screen, through a shooting unit and obtains RGB three-primary-color values of all pixel points of a first frame of image in the video stream so as to be compared with a standard image. When the RGB three-primary-color values of all pixel points in the first frame of image meet demands, a second frame of image in the video stream continues to be obtained so as to judge whether displacement difference values of all pixel points of a specific object in the first frame of image meet demands and the displacement difference values of all pixel points of a specific object in two adjacent frames of images are compared so as to judge whether demands are met and when the displacement difference values of all pixel points of the specific object in the two adjacent frames of images meet demands, a tested to-be-tested screen is a non-defective product, or else the to-be-tested screen is a defective product. Therefore, the screen test method is capable of accurately testing whether the to-be-tested screen is defective or not so that the trouble of the prior manual testing of screens is substituted.

Description

technical field [0001] The invention relates to the testing field, in particular to a screen testing system and method. Background technique [0002] At present, after the production of mobile phone products, the quality of the mobile phone display screen is observed by human eyes, but there are many places that are difficult to detect by human eyes. For example, when the display screen displays information, the display at the corners is not easy to find. Moreover, testing the display screen by manpower is also a waste of cost. Contents of the invention [0003] In view of the above, it is necessary to provide a screen test system, a screen test system, the screen test system is applied to test equipment, the test equipment includes a shooting unit, the test equipment stores the RGB three primary colors of each pixel point of the standard image Value, wherein the standard image is an image displayed on a good product screen to be tested, the system includes: a photographi...
