Description

Technical Field

[0001] The utility model relates to the technical field of backlight modules, and particularly relates to a backlight structure with adjustable viewing area size. Background Technique

[0002] A backlight module is an electronic device component integrating a backlight source. It is usually applied in various display devices. By adding a backlight source behind the display area, the backlight module can provide sufficient light brightness, so that the display content can be clearly visible in most environments.

[0003] For the products shipped by the module, customers often require measuring the surface scan uniformity data of the products. To ensure the accuracy of the data, it is also necessary to measure the surface scan uniformity data of a single backlight synchronously.

[0004] According to the design requirements, the size of the viewing area of this single backlight is often larger than the display area of the module. In order to make the backlight viewing area close to the module display area, it is often simulated by pasting black light-shielding paper on the backlight viewing area. In this way, the test results are more accurate, but this method requires manual attachment of the black light-shielding paper, which has certain operational inconvenience and is more complex in operation.
