Abstract: The present disclosure relates to a chip on film (COF) single-layer flexible printed circuit board, including: a flexible packaging substrate including a bonding area and a controlling chip being packaged on the flexible packaging substrate. The bonding area of the flexible packaging substrate is configured to bond with a bonding area of an array substrate. The controlling chip electrically connects to the bonding area of the flexible packaging substrate. The controlling chip and the bonding area of the flexible packaging substrate are configured on the same side of the flexible packaging substrate, and a portion of the flexible packaging substrate is bent at least one time. As such, the controlling chip faces away the array substrate, the cost and the complexity of the post-process may be reduced, and the COF single-layer flexible printed circuit board may be shipped in the folding manner.

Abstract: A LCD and the display method thereof are disclosed. The LCD includes a light guiding plate, a light source, a QD media layer, a first polarizer, and an advanced polarization conversion film (APCF). The QD media layer is arranged between the light source and the first polarizer, the first polarizer and the APCF are arranged between the QD media layer and the light guiding plate. The light beams emitted from the light source pass through the QD media layer and activate the QD media layer to emit lights In this way, the brightness of the reflective LCD may be enhanced.

Abstract: The present disclosure relates to a backlight module and a display panel. The backlight module includes a light source, a QD tube and a light guiding plate, the light source being arranged at a lateral side of the light guiding plate, the QD tube being arranged between the light source and the light guiding plate. A light incident surface of the light guiding plate depresses toward an internal of the light guiding plate such that one side of the QD tube is embedded into the light guiding plate and the other side of the QD tube abuts against the light source. The structure is simple and may be easily assembled. In addition, such configuration contributes to the light and thin design.

Abstract: The present disclosure discloses a liquid crystal display driving device, including a time sequence controller, a data and scan drivers, a liquid display panel and a programmable gamma circuit connected to the data driver. The time sequence controller is respectively connected to the data and scan drivers. The data driver coverts an image data to an analog voltage. The programmable gamma circuit outputs a reference voltage to the data driver and used to assign the reference voltage in real time. The reference voltage corrects the analog voltage so the data driver outputs a gray-level voltage to a liquid crystal unit opened by the scan driver to display an image frame or a black frame. It overcome a problem of overlapping a left-eye and right-eye image frames and at the same time greatly decreases a power consumption of a system. The present disclosure also discloses a liquid crystal display driving method.
