Abstract:
The present invention relates to a device and a method for measuring an axial polarizing angle of a polarizer. The apparatus can have a to-be-measured polarizer disposed therein, and comprises a light generating device, a light polarizing device and a measurement comparison device. The light generating device provides a light source. The light polarizing device is disposed corresponding to the light generating device to load the to-be-measured polarizer, and measures a light signal after the light source passes through the to-be-measured polarizer without rotating the to-be-measured polarizer, and transforms it into readable data. The measurement comparison device is electrically connected with the light polarizing device and has at least one preset comparison data to receive the data provided by the light polarizing device and compare it with the comparison data. Thus, after comparing the data provided by the light polarizing device with the comparison data, an axial polarizing angle of the to-be-measured polarizer is quickly and accurately measured and calculated.
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.
Abstract:
An exemplary double-sided liquid crystal display (LCD) (200) includes a first liquid crystal panel (212), a first optical film assembly (211), a light guide plate (230), a second optical film assembly (211), and a second liquid crystal panel (222) arranged in that order from bottom to top. An area of the second liquid crystal panel is less than an area of the first liquid crystal panel, and an area of the second optical film assembly is less than an area of the first optical film assembly. The second optical film assembly of the double-sided LCD has a size no larger than that needed to perform its function in respect of light beams propagating therethrough from the light guide plate to the second liquid crystal panel. Therefore, the double-sided LCD is cost-efficient.
Abstract:
A liquid crystal display (100) has a first panel (14); a second panel (12) opposite to the first panel; a liquid crystal layer sandwiched between the two panels; and at least one light source (20) for providing light beams. The first panel directly introduces the light beams from the light source into the LCD for displaying images.

Abstract:
A transflective LCD panel has a transmissive region and a reflective region and includes a first substrate, a second substrate opposite to the first substrate, a reflective plate formed on the second substrate and located within the reflective region, and a first liquid crystal layer and a second liquid crystal layer that are filled between the first substrate and the second substrate. The first and second liquid crystal layers correspond to the transmissive and reflective regions, respectively. The second liquid crystal layer is doped with a chiral material. When a voltage is applied, liquid crystal molecules in a middle section of the first liquid crystal layer are substantially arranged in a tilt angle θ, and the liquid crystal molecules of the second liquid crystal layer are tilted by the tilt angle and further twisted.

The planar light emitting mechanism comprises a rectangular light guiding plate and a lamp. The lamp is disposed on a side of the light guiding plate, having a brighter effective emitting area and two curved darker emitting areas. The darker emitting areas are adjacent to the corners of the rectangular light guiding plate, wherein the brighter effective emitting area is between the darker emitting areas.

Abstract:
An optical compensation structure and its fabricating process are disclosed. The optical compensation structure comprises an upper polarizer film, a transparent substrate, a first retarder film (C+ plate), and a second retarder film (A-plate). The upper polarizer film provides polarization function and possesses a top surface and a bottom surface. The transparent substrate is directly laminated onto the top surface of upper polarizer film. The first retarder film is coated with a bonding layer made of crosslinking agent on one side and the bonding layer is directly laminated onto the bottom surface of upper polarizer film. The second retarder film binds to the side of first retarder film away from the upper polarizer film. The optical compensation structure is coated with the bonding layer to address the drawback of prior art where the upper polarizer film and the first retarder film are not closely adhered to each other, thereby allowing the use of one less substrate and offering a thinner compensation structure. When applied to liquid crystal display (LCD), the optical compensation structure improves the contrast and color shift problems of LCD at oblique viewing angles.
