Abstract

The invention provides an optical simulation device of a backlight source. The optical simulation device comprises a first bearing unit, a second bearing unit, a distance measurement unit and a control unit. The first bearing unit is used for placing a light source, and the second bearing unit is used for placing a light guide plate. The distance measurement unit is used for obtaining a distance between the light source and the light guide plate. The control unit is connected with the first bearing unit and the second bearing unit and used for controlling relative position between the first bearing unit and the second bearing unit. The optical simulation device of the backlight source adjusts the distance between the light source of the backlight source to be simulated and the light guide plate by controlling the first bearing unit and the second bearing unit, obtains the distance between the light source at the corresponding position and the light guide plate through the distance measurement unit, can actually simulate the optical effect of backlight source products, accordingly can perform actual optical simulation before the products are manufactured, and performs actual verification to the actually simulated backlight source to be developed.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to an optical simulation device of a backlight source. Background technique [0002] The LCD display itself does not emit light. In order to clearly see the content displayed on the LCD display, it needs the support of the backlight to obtain color rendering. The backlight is generally composed of necessary optical components such as a light source, a diaphragm, a reflector, a light guide plate, and a back plate. [0003] The development and design of the existing backlight source is first simulated by optical simulation software, and key parameters such as the number of LEDs and the distance from the light guide plate are set, calculated from the design software, and then produced through the development of molds, but the results of simulation design calculations are often simulated. Deviations from the results in actual samples will affect the optical effect of the backlight, an...
