Apparatus having negative dot pattern used in machining thin light guide plate

Abstract

An apparatus having a negative dot pattern used in machining a light guide plate. The apparatus includes a machining table unit disposed under the light guide plate, a drive unit disposed over the machining table unit, a plurality of adjustment units disposed over the light guide plate, a plurality of machining support units disposed over the light guide plate, and a plurality of machining units disposed over the light guide plate. When each machining unit has reached a machining position by being transported in transverse and vertical directions above the light guide plate by the drive device, each machining unit engraves dots while the light guide plate is being carried in the machining direction. After the light guide plate is machined, the drive device is transported to an upper position and to a position where next dots are intended to be engraved, and the next dots are sequentially engraved.

Description

technical field [0001] The present invention relates to a thin plate type light guide plate processing device for imprinting engraved small dot images. Background technique [0002] Generally, a display is a device that outputs an image based on an image signal. Displays such as liquid crystal displays (LCD, Liquid Crystal Display) have a color panel that outputs RGB colors. Since the color panel itself does not emit light, a backlight module that illuminates the color panel is provided to output images. [0003] A conventional backlight module includes a light source body for irradiating light to a display to generate a light source, and a light refraction device for uniformly supplying the generated light to a flat panel through refraction. The light refraction device further includes a light guide plate having a refractable image that refracts light from the light source body, and a light adjustment device that diffuses the light refracted by the light guide plate and ad...

Problems solved by technology

However, if the light guide plate is a thin plate, if a scraper with multiple serrations is used for processing, it will bend at the position of the multiple serrations that are pressed and cause defects.

[0011] Moreover, the surface of the thin-plate light guide plate itself has been bent before processing, so if it is formed by ordinary scraping, it cannot overcome the height difference due to the bend, and the depth of the bent part will be increased. Different, or if the bending of the thin plate protrudes, it will be cut off when engraving and cause defects

[0012] In addition, since a plurality of serrations are processed at a time, the impact of processing is transmitted to the thin plate-type light guide plate at one time, so that bending occurs during processing deformation, and the processing depth of the curved part is different or cut off.
