Method and device for optimizing mesh point of light guide plate

Abstract

The invention is suitable for the field of design of mesh points of a light guide plate, and provides a method and a device for optimizing the mesh points of the light guide plate. The method comprises: determining the position of each mesh point according to the size of the light guide plate and the horizontal spacing and vertical spacing of centers of adjacent mesh points, and determining firstmesh point density distribution according to the position relationship of an LED (light-emitting diode) lamp and the light guide plate; obtaining the center coordinates, shape and area of a supplementary point area to determine the supplementary point area, changing the mesh point density of the supplementary point area according to the obtained supplementary point strength, and thus obtaining second mesh point density distribution, wherein the supplementary point strength is used for determining the ratio of changes in the sizes of mesh points in the supplementary point area; and setting different mesh point marks for the mesh points with different sizes according to the second mesh point density distribution, and displaying the mesh point marks. The distribution of the mesh points of the light guide plate can be simulated. Moreover, different mesh point marks can be set for the mesh points according to the sizes of the simulated mesh points, the sizes of the mesh points can be directly distinguished, the development cost can be reduced, and the development cycle can be shortened.

Description

technical field [0001] The invention belongs to the field of network point design of a light guide plate, and in particular relates to a method and a device for optimizing the network point of a light guide plate. Background technique [0002] The light guide plate is an important component in the light-emitting diode (Light Emitting Diode, LED) side-entry backlight module. The distribution of the dots of the light guide plate is based on the position of the LED lamp, and the distribution of the dots directly determines the optical quality of the backlight module. Performance affects the user's sensory experience. Taking a light guide plate with one side of the bottom side receiving light as an example, the dot density value on the light incident side is relatively small, and as the distance increases, the dot density gradually increases to balance the light guiding intensity of the entire light guide plate. However, it is not feasible to set the distribution of dots simply...
