Abstract: The present disclosure relates to a light guide plate and a display apparatus having the same. The light guide plate includes a transparent light guide plate body and a plurality of microstructures. The transparent light guide plate body has a first surface and a second surface opposite to the first surface, wherein the first surface has a surface roughness of less than or equal to 100 nm. The microstructures are disposed on the first surface. A light beam from the transparent light guide plate body is reflected by the microstructures, and another light beam from the transparent light guide plate body passes through the first surface between the microstructures.

Abstract: The present invention relates to a light guide plate and back light module having the same. The light guide plate includes a light guide plate body and a plurality of microreliefs. The light guide plate body has a light-emitting surface and a reflecting surface. The microreliefs are disposed on the reflecting surface. Each of the microreliefs has an outer surface and a base area. The outer surface is a curved surface, and the base area contacts the reflecting surface. A ratio of the totally height of each of the microreliefs to the diameter of the base area of each of the microreliefs is between 1/7 and ¼. As a result, the light guide plate has higher light extraction efficiency.

Abstract: The present invention relates to a backlight module, light guide plate thereof and ink thereof. The ink includes a base resin and an additive. The additive is dispersed in the base resin for increasing the printability of the ink. The additive comprises a polymer having hydroxy functional group, ester functional group, ether functional group or combination thereof. Use of the ink of the present invention will reduce the color difference and the variation of color temperature of the light guide plate. In addition, the ink has higher flowability, which increases the printability of the ink.

Abstract: The present invention relates to an optical unit and light guide plate and ink thereof. The ink includes a base resin and a plurality of fine particles. The base resin has a first refractive index. The fine particles have a second refractive index and are dispersed in the base resin. The fine particles are made of organic polymer. The difference between the first refractive index and second refractive index is less than 0.15. The use of the ink will lower the color difference and the variation of color temperature of the light guide plate or the optical unit.

Abstract: The present invention relates to a light guide plate and ink thereof. The ink includes a base resin and a plurality of hollow structures. The hollow structures are dispersed in the base resin and comprise air therein. In the present invention, the hollow structures in the ink give the light guide plate higher light extraction efficiency.

The pointing module is capable of transmitting cursor-related data. The input module is capable of transmitting data related to numbers and symbols of algorithm. The calculation module is capable of performing calculation based on data received from the input module. The display module is capable of showing data provided through the input module and data provided from the calculation module.

Abstract: An apparatus for taking and transmitting picture includes a picture-taking device for taking pictures and for transforming the pictures into data and a data-transmitting device for transmitting the data transformed by means of the picture-taking device. The picture taking and transmitting devices may be used in a security system. The security system includes a controller and a sensing device. On sensing an external force, the sensor notifies the controller that in turn actuates the picture-taking device and the data-transmitting device. The picture taking and transmitting apparatus may be used in traffic security system. The traffic security system includes a controller and a sensing device. On sensing a vehicle running faster than a speed limit or across a stop line, the sensor notifies the controller that in turn actuates the picture-taking device and the data-transmitting device.
