A new type of light guide plate and its processing technology

Abstract

This application belongs to the technical field of the light guide board, involving a new type of light guide board processing process, which includes the following steps: LED lights tightly paste the light surface of the light board: put the LED light strip to the light surface of the light guide board, so that the LEDLights close to the light surface of the light board; LED light inter -lamp point glue: point glue between the empty position between the adjacent LED lights, the gap between the input of the light and the light guide plate and the adjacent LED lampBetween gaps; the glue is optical glue, and the refractive index of optical glue is greater than equal to the refractive index of the light guide board; UV baking solidification: solidify the optical glue for optical glue through UV, thereby fixing the LED light to the input of the light guide plate.At the same time, the gap between the optical glue supplementation of the optical glue supplement LED light and the light guide board and the gap between the adjacent LED lights.This application can greatly eliminate the assembly gap when the existing technology is used in the existing technology, thereby reducing the loss of the light energy of the LED lamp and increasing the light energy utilization rate of the LED light.

Description

technical field [0001] The present application relates to the field of light guide plate processing, in particular to a novel light guide plate and a processing technology thereof. Background technique [0002] Backlight sources in electronic devices or displays usually use backlight modules, such as figure 1 As shown, the backlight module includes an LED light bar 2 and a light guide plate 1 . The LED light bar 2 is a bar-shaped component product formed by attaching a plurality of LED lights 21 to a flexible circuit board. The light guide plate 1 is generally in the shape of a flat plate, the side end surface is the light incident surface 11 , and the upper and lower surfaces are the light exit surface and the dot surface respectively. The LED light bar 2 is assembled on the side end face of the light guide plate 1 , and the point light sources emitted by a plurality of LED lamps 21 are injected into the interior of the light guide plate 1 through the light incident surfa...

Problems solved by technology

However, the inventor found in actual production that when the LED lamp 21 and the light guide plate 1 are assembled using the assembly process of the lamp strip glue 3, a gap is likely to appear between the LED lamp 21 and the light incident surface 11 of the light guide plate 1, resulting in LED The light energy of the lamp 21 is greatly lost at this gap, and the test data shows that the light energy utilization rate of the LED lamp 21 in this case is only about 70%.
