Processing method based on light guide plate mesh point shadow reinforcement and processing apparatus

Abstract

The invention discloses a processing method based on light guide plate mesh point shadow reinforcement and a processing apparatus. The method comprises: A, an operation instruction of a user is received to define a data type of light guide plate mesh point shadow reinforcement as well as an initial value is assigned to corresponding data; B, information of a mesh point area on a light guide plate is obtained and it is determined whether the obtained mesh point area is a reinforcement area or not; if so, a step C is entered; C, when it is determined that the obtained mesh point area is a reinforcement area, according to the defined data type of the light guide plate mesh point shadow reinforcement and the corresponding assignment data, an astroid is employed to carry out reinforcement; and after the reinforcement is completed, a step D is entered; and D, a corresponding mesh point graph surface is generated and is output. According to the invention, when the processing method and the processing apparatus are employed, it can be avoided that a non-shadow area is compensated additionally; and the method and the apparatus are mainly applied to a guide light plate mesh point design in an LED back light module group, so that a visual effect of an LED liquid crystal module group can be improved; and moreover, advantages of high efficiency and good security are realized.

Description

technical field [0001] The invention relates to the field of shadow reinforcement of dots of a light guide plate, in particular to a processing method and device based on shadow reinforcement of dots of a light guide plate. Background technique [0002] With the sharp increase in the demand for LED LCD TVs, the field of LED backlight modules is developing rapidly. From the perspective of energy saving, environmental protection, and cost, the way of LED light input is gradually changing from four-side light input to single-side light input, and the center of the LED light The spacing gradually becomes larger, and there are situations where the center spacing of LED lights varies. Therefore, there are dark areas and shadows after the TV backlight module is turned on. [0003] The generation of dark shadows is due to the fact that the luminous flux radiated from the dark area is smaller than that of the surrounding areas, thus creating a contrast with the surrounding bright ar...

Problems solved by technology

The method for reinforcing the elliptical area in the prior art will have the following problems when correcting the dots: figure 1 As shown, it can be seen that the dark part outside the triangle 100 (that is, the reinforcement area within the triangle area 100 to the oval area 110) is additionally reinforced, which in turn will cause other optical inhomogeneities
