Abstract:
An exemplary backlight module (300) has at least two light guide plates (322, 323) spacing a predetermined distance and at least one light source (324), the at least two light guide plates each having a light incident surface (31, 32). The at least one light source is disposed between the at least two light incident surfaces.
Abstract:
An exemplary backlight module (20) includes a light guide plate (22) having a light incident surface (224), a plurality of light sources (23) adjacent to the light incident surface, a frame (24) for receiving the light sources and the light guide plate, and a colored reflective structure (220) disposed in the frame. Some of the light beams emitting from the light sources are transmitted to the colored reflective structure and converted to reflected light beams having a corresponding color. The reflected light beams further mix with light beams emitting from the light sources and generate light beams in desired color system. A liquid crystal display (200) using the backlight module is also provided.
Abstract:
A light guide plate (20) includes a main body, a light incident surface (201), a light emitting surface (202), and a plurality of light diffusing structures (204), arranged within the main body according to a predetermined pattern. The light diffusing structures are formed using an engraving method. The light diffusing structures are formed within the light guide plate, which protects the light diffusing structures from being damaged. In addition, the laser engraving method and the ultrasonic engraving method can be conveniently controlled, so that the arrangement and distribution of the light diffusing structures can be easily controlled. This enables the light guide plate to be configured with optimal optical characteristics, thereby yielding an improved light utilization ratio.
Abstract:
A flexible printed circuit includes a flexible substrate, a plurality of first conductive wires, and a plurality of second conductive wires. The flexible substrate includes a first surface and a second surface facing the first surface. The first conductive wires are provided on the first surface. The first conductive wires extend from an edge of the flexible substrate to another edge of the flexible substrate. The second conductive wires are provided on the second surface. The second conductive wires extend from an end of the flexible substrate to a predetermined portion of the flexible substrate. A part of each second conductive wire at the predetermined portion of the flexible substrate is electrically connected with the first conductive wire via a conductive structure.
Abstract:
An exemplary flexible printed circuit (20) includes a primary body (210) and a secondary body (220). The primary body includes a primary connection portion (211), and a primary engaging portion. The secondary body includes a secondary connection portion (221) and a secondary engaging portion (223). The primary body and the secondary body are electrically connected by connecting the primary engaging portion and the secondary engaging portion together.

Abstract:
A light guide plate (10) includes a light incident surface (12), a light emitting surface (14) adjoining the light incident surface, a bottom surface (16) opposite to the light emitting surface, and a plurality of holes (18). Each hole has at least one open end terminating at the light emitting surface or the bottom surface. The holes may be through holes or blind holes. When incident light beams reach the holes, the light beams are reflected or refracted in directions toward the light emitting surface. Therefore a distance traveled by a portion of the light beams in the light guide plate is shortened, and the loss of light energy is reduced. This enables the light guide plate to provide a high ratio of light utilization. Additionally, the through holes reduce the weight of the light guide plate. The light guide plate can be generally rectangular or wedge-shaped.
