摘要:
An exemplary optical plate includes a base and an array of micro-structures. The base includes a first surface and a second surface opposite to the first surface. The micro-structures are provided at the first surface. Each micro-structure includes a base surface substantially coplanar with the first surface of the base and two side surfaces. The base surface has an approximately olive-shaped profile enclosed by two arc-outlines. The two side surfaces extend obliquely from the two arc-outlines and intersect at a ridge of the micro-structure.

A touch module includes a touch element, a shell body and a decoration film. The shell body defines a curved touch area. The curved touch area is figured to touch the touch element. The touch element covers the curved touch area. The decoration film is an outer layer of the touch module. The shell body, the touch element and the decoration film are incorporated into an integrated structure.

A touch panel including an optical element and a chromaticity improving layer is provided. A light transmittance of the optical element to the short wavelengths visible light is lower than a light transmittance to the long wavelengths visible light. A light transmittance of the chromaticity improving layer to the short wavelengths visible light is higher than a light transmittance to the long wavelengths visible light. A display device using the touch panel is also provided.

An exemplary light guide plate (12) includes a substrate (120) having an emitting surface (124), and a plurality of parallel V-shaped grooves (126) provided at the emitting surface. Each of the V-shaped grooves maintains an oblique angle relative to a long side of the substrate, and the angle is in the range from 5° to 44.9°. An associated device employing the light guide plate can provide good viewing performance.

An exemplary light guide plate (31) includes a light incident surface (310), a light output surface (312) adjacent to the light incident surface, and a bottom surface (313) opposite to the light output surface. The bottom surface includes a plurality of W-shaped structures (314) thereat. With such configuration, the output light beams can be concentrated to make the intensity distribution of the output light beams to be even. A backlight module employing the light guide plate is also provided.

An exemplary backlight module (2) includes a light guide plate (20) and a reflective plate (26). The light guide plate includes an incident surface (21) and a bottom surface (23) adjacent the incident surface. The reflective plate is disposed adjacent to the bottom surface, and includes a reflective projection (268) which faces the bottom surface. By adjusting a width, a height, a location and other parameters of the reflective projection, an emission brightness of the light guide plate is controllable.
摘要:
A method for making a touch module is provided. The method includes the following steps. A touch element, a decoration film and a mold is provided. The touch element is flexible, the mold includes a female mold, and a male mold corresponding to the female mold. The touch element is fixed on the female mold, and the decoration film is fastened to the male mold. The mold is closed. A plastic material is injected into the mold until the plastic material is formed into a shell body, and the touch module including the touch element and the decoration film is formed. Wherein, both the touch element and the decoration film are fixed on the shell body. The mold is opened. And the touch module is removed.
