Double-camera module group

The invention relates to a double-camera module group, and the module group comprises a circuit board, a lens seat, two image sensors, two lens module groups, a liquid crystal lens, and a welding pin. The two lens module groups are disposed on the same lens seat, and the bottom surface of the lens seat is connected with the circuit board. Moreover, the top surface of the lens seat is provided with the liquid crystal lens, thereby enabling the liquid crystal lens to cover the two lens module groups. The welding pin in the lens seat can enable the liquid crystal lens to be electrically connected with the circuit board. During assembly, the focuses of the lens module groups are adjusted, and the liquid crystal lens is used for focusing during photographing. In other words, the circuit board supplies power to the liquid crystal lens through the welding pin. The path of light passing through the liquid crystal lens is correspondingly changed during different voltages, and the focusing function is achieved under the condition of no voice coil motor. Therefore, the module group can effectively prevent the magnetic interference between two voice coil motors, and improves the image quality. Moreover, the two lens module groups achieve the focusing function through the liquid crystal lens, so the module group can effectively solve a problem that the movement of the two lens module groups is not consistent, and improves the image quality.

Backlight module and display device

The invention discloses a backlight module and a display device, so that the side bright line of the backlight module is reduced, and the image quality of the backlight module is improved. The backlight module comprises a rubber frame and a light guide plate arranged in the rubber frame, wherein avoiding structures are respectively arranged on the sides, close to the incident light side, of two non-incident light sides parallel to the rubber frame; the side, away from the end face of the light guide plate, of each avoiding structure is closed through a surface sealing structure. The avoiding structures provide larger gaps between the end face of the light guide plate and the surface sealing structures, so that the optical path of the light radiated out from the end face of the light guide plate can be increased, a part of light radiated out from the end face of the light guide plate is absorbed by the surface sealing structures, the other part of light enters into the light guide plate again after being reflected by the surface sealing structures, and the distance of the light entering into the light guide plate again from the position where the light is radiated out from the upper surface of the light guide plate to the side of the rubber frame is longer, so that the scheme can effectively reduce the side bright line of the backlight module and improve the image quality of the backlight module.

Pixel structure and display device

The invention provides a pixel structure and a display device. The pixel structure comprises a plurality of pixel units. Each pixel unit comprises a first sub pixel with a first color, a second sub pixel with a second color and a third sub pixel with a third color, wherein the first sub pixel is provided with a first adjacent side with a first length and a second adjacent side with a second length, the second sub pixel is provided with a first adjacent side with the first length and a second adjacent side with a third length, and the third sub pixel is provided with a first adjacent side with the second length and a second adjacent side with the third length. According to each pixel unit, the first adjacent side of the first sub pixel is adjacent to the first adjacent side of the second sub pixel, the second adjacent side of the first sub pixel is adjacent to the first adjacent side of the third sub pixel, and the second adjacent side of the second sub pixel is adjacent to the second adjacent side of the third sub pixel. According to the pixel structure and the display device, due to the fact that the adjacent sides are arranged between every two adjacent sub pixels, the light blending effect between the sub pixels inside each pixel unit is improved, and the image quality of a display frame is improved.

Apparatus and method for image conversion and automatic error correction for digital television receiver

Disclosed is an apparatus and method for image conversion and automatic error correction for a digital television receiver (TV) which can improve the picture quality by converting an image signal for a TV or PC that displays an image having an RGB format into an image signal of YPbPr for the digital TV and automatically correcting an error produced in the received image signal. The apparatus includes an image receiving and converting section for converting an image receiving and converting section for converting received RGB image data into image data of a digital TV format and rearranging parity bits and error information bits produced from the converted image data to form one image signal, a storage and image providing section for receiving the image signal from the image receiving and converting section, storing the image signal in a memory bank and providing the image signal so as to detect and correct an error produced in the image signal, and an error correcting and outputting section for receiving the image signal from the storage and image providing section, correcting the error by computing the parity bits and the error information bits from the original image data of the image signal, and interpolating the image to match a 16:9 aspect ratio for the digital TV.
