Abstract
The invention discloses a light guide plate (100) which is applied to a backlight source. The light guide plate (100) disclosed by the invention comprises a light guide plate main body (110), whereinthe plate surface, which deviates from the light emitting side of the backlight source, of the light guide plate main body (110) comprises a first region (111) and a second region (112), the first region (111) surrounds the second region (112), the first region (111) and the second region (112) are both provided with a plurality of first optical bulges (120) distributed at intervals, the second region (112) is provided with a plurality of second optical bulges (130) distributed at intervals, and the projection area of the first optical bulges (120) is larger than that of the second optical bulges (130) in the direction perpendicular to the plate surface. According to the scheme, the problem that the hole number of the existing light guide plate is difficult to identify can be solved. The invention discloses a backlight source, electronic equipment, a light guide plate hole number identification method and a light guide plate hole number identification device.
Description
technical field [0001] The invention relates to the technical field of light guide plate production for backlight sources, in particular to a light guide plate, a backlight source, electronic equipment, and a method and device for identifying hole numbers of the light guide plate. Background technique [0002] With the rapid development of electronic devices (such as mobile phones, tablet computers, etc.), users have higher and higher requirements for electronics. Requirements such as ultra-thin, high-brightness, and a larger screen ratio have led to shorter and shorter development cycles for backlight sources. A large number of materials are rapidly added, which makes the backlight source bear a greater risk of abnormality in the initial mass production of the product, especially the light guide plate of the backlight source. [0003] We know that the backlight source cooperates with the LCD screen, and the backlight source provides the backlight to realize the display of ...
