Abstract: A display panel vacuum suction system includes a control device, a robot arm, and a vacuum device. The robot arm includes two or more retractable rods, and each of the retractable rods is connected with a vacuum plate. Each vacuum chamber is disposed in each of the vacuum plates, and each vacuum hole is disposed on a surface of each of the vacuum plates, wherein each vacuum chamber is connected with the vacuum device by a suction pipe. The control device controls expansion and retraction of the retractable rods of the robot arm, so that the vacuum plates connected with the retractable rods can be combined to pick up a single display panel or pick up two display panels respectively. By combining vacuum plates, and controlling the opening or closing of the vacuum holes of each of the vacuum plates, different sizes of display panels can be sucked.

Abstract: A liquid crystal display device and a backlight control method thereof are provided. In response to that average pixel brightness of image data is less than a threshold, a first backlight driving signal is generated based on gray level information of the image data and a second backlight driving signal is generated based on saturation information of the image data. A convolution operation is performed on the first and the second backlight driving signal to output a backlight driving signal. The backlight driving signal is modulated and provided to a backlight module for producing backlight to a liquid crystal panel. Power consumption of the backlight module is lowered and meanwhile a dark effect caused in displaying images of a pure color is improved.

Abstract: The present invention provides a liquid crystal display panel and a display device. The liquid crystal display panel includes: a first substrate; a second substrate disposed opposite to the first substrate; liquid crystals filled between the first substrate and the second substrate; and first support walls disposed on the first substrate to support the second substrate, wherein the first support walls are disposed around the first blind hole and formed with a liquid crystal channel having a size larger than a size of each of the liquid crystals. In the present invention, by disposing the first support walls on the first substrate and around the first blind hole, when the first substrate and the second substrate are bonded by vacuum cell-assembly, the edge of the blind hole is supported, such that recessing of the glass substrate can be mitigated.

Abstract: The invention provides a curved display panel and a manufacturing method thereof. The curved display panel includes a glass substrate, a metal wire grid polarizer, an array substrate, a color filter substrate, and a thin film substrate, wherein the metal wire grid polarizer is disposed on the glass substrate, and the array substrate is provided on the metal wire grid polarizer. The present invention uses a metal wire grid polarizer to replace the lower polarizer in the prior art. The metal wire grid polarizer can be placed under the array substrate by using ductility and high temperature resistance of a metal, and prevent the curved display panel from occurrence of light leakage due to the retardation effect of glass by using polarization characteristic of the metal wire grid polarizer, thus improving viewing angles of a liquid crystal display, and increasing brightness uniformity of curved display of the panel.
