Abstract: The present invention provides an OLED display and a manufacturing method thereof. The OLED display of the present invention is such that in a thin film encapsulation layer, an inorganic passivation that is located under and adjacent to each organic buffer layer forms a stepped zone at a portion between an outer edge of the organic buffer layer and an outer edge of the inorganic passivation layer and each stepped zone is provided with a DLC layer that covers the stepped zone. In other words, the present invention uses DLC for later side encapsulation and in the thin film encapsulation layer, each organic buffer layer is provided, on an outer side thereof, with a DLC layer to thereby effectively block external moisture and oxygen from attacking the OLED device from a lateral side and also to eliminate an issue of loss for light of a top emission device to travel through DLC.

Abstract: The present disclosure relates to a driving method and a driving device of display panels. The driving method includes: dividing a saturation interval of an original image frame to be displayed by a display panel into a plurality of sub-saturation intervals; obtaining saturation values corresponding to each of the pixels in the original image frame; calculating numbers of pixels in the original image frame falling within each of the sub-saturation internals in accordance with the saturation values corresponding to each of the pixels. In this way, the backlight brightness outputted by the backlight module may be adjusted in accordance with the saturation values of the original image frame so as to enhance the low brightness issue when a pure-color image is displayed by the display panel configured with RGBW sub-pixels.

Abstract: A gate driving circuit disposed on an array substrate and an LCD using the same are described. The gate driving circuit on the array substrate comprises a plurality of sequentially connected gate driving units. The gate driving circuit unit comprises an input module, a reset module, a latch module and a signal processing module. The signal processing module receives the current inverse stage-transmitting signal XQ(N), the low voltage signal, a second clock signal and a third clock signal to control on/off statuses of two transistors by the current stage-transmitting signal Q(N) so that the two transistors forms Nth gate signal G(N) and gate signal (N+1)th based on the second clock signal and the third clock signal. The present invention utilizes less clock signals and transistors, which is favorable to the narrower LCD's frame design and solves the problem of manufacturing process restriction of the LCD panel.

Abstract: A driving device and a liquid crystal display device are disclosed. In the driving device, a charging efficiency difference between a positive polarity voltage and a negative polarity voltage on a pixel can be compensated through increasing a duration of a gate driving signal, shortening a time period during which the positive polarity voltage is provided to a source line, and prolonging a time period during which the negative polarity voltage is provided to the source line. In this manner, the technical problem of non-uniform brightness of an image displayed in a traditional liquid crystal display panel and unsatisfactory display effect thereof can be solved.
