An optical member that lends itself to be more cost-effectively manufactured than a conventional optical member is presented. A display device made with the optical member can be thinner than the conventional optical member. The optical member includes a light-incident face that receives light emitted from a lamp positioned at a side of the optical member, a light-exiting face that is in a plane perpendicular to the light-incident face, and a light reflecting face opposite to the light-exiting face. A light-concentrating pattern having a plurality of concentric circles is formed on the light-exiting face. The light-concentrating pattern may be the Fresnel lens pattern. A diffusing pattern for diffusing the light is formed on the light reflecting face. Since patterns are formed on the optical member, additional optical sheet such as a prism sheet, a reflective polarizing sheet, a diffusion sheet, etc., is unnecessary.

The invention discloses a method and a system for synchronously adjusting display parameters of an MIPI (mobile industry processor interface) module when the MIPI module displays images. According to the method and the system, adjustment instructions and response parameters are received and transmitted through a frame blanking area of RGB (red, green, blue) signals. The method specifically comprises steps as follows: (1) the frame blanking area of the RGB signals is detected, and an identifier of the frame blanking area is generated; (2), when the identifier of the frame blanking area is detected, conversion from the RGB signals to MIPI signals is stopped, module parameter display and adjustment instructions cached in advance are converted into LPDT (lower power data transmission) data one by one and sent to the MIPI module; (3), after all the display and adjustment instructions in the frame blanking area are all transmitted and the response parameters returned by the MIPI module are received, a state indication signal is generated; (4), when the state indication signal is detected, an MIPI conversion control signal is generated, conversion from the RGB signals to the MIPI signals is started, and RGB image data are converted into the MIPI signals. With the adoption of the method and the system, the images are displayed in the MIPI module, meanwhile, the display parameters of the MIPI module are synchronously adjusted, and the image display quality of the MIPI module is not influenced.
