The first boost voltage module includes a first detection unit that detects an output current of the first boost voltage module, and the second boost voltage module includes a second detection unit that detects an output current of the second boost voltage module. The monitor module includes a current comparing unit coupled to the first detection unit and the second detection unit, and an actuator coupled to the current comparing unit. The actuator controls running states of the first boost voltage module and the second boost voltage module. | 10-02-2014 |
20140267444 | AMOLED Display Device and Method for Precisely Compensating Aging Thereof - The present invention relates to an AMOLED display device, which includes a display panel; a data processor, which processes image data from a video source and compensation data from a compensation unit and outputs compensated image data, the image data having a first color depth, the compensation data and the compensated image data having a second color depth that is greater than the first color depth; a frame rate control module, which adjusts the compensated image data to the first color depth; a timing controller, which generates a timing control signal; a driver, which drives the display panel; a display measurement module, which measures homogeneity of displaying of the display panel; and a compensation unit, which generates compensation data of second color depth. The present invention also provides a method for precisely compensating an AMOLED display device. | 09-18-2014 |
20140184978 | SLIM BEZEL LIQUID CRYSTAL DISPLAY DEVICE - The present invention provides a slim bezel liquid crystal display device, which includes a rear enclosure, a front enclosure mating the rear enclosure, and a liquid crystal display module arranged in the rear enclosure. The liquid crystal display module has four sides each forming a plurality of projections. The rear enclosure forms retention slots corresponding to the projections. The projections are receivable in and retained by the retention slots to fix the liquid crystal display module in the rear enclosure. With the projections formed on the liquid crystal display module and the retention slots formed in a rear enclosure, the projections are respectively receivable in and retained by the retention slots to fix the liquid crystal display module in the rear enclosure. The structure is simple and the assembling operation is easy so as to effectively achieve bezel slimming and device thinning of a liquid crystal display device. | 07-03-2014 |
20140104535 | SLIM BEZEL LIQUID CRYSTAL DISPLAY DEVICE - The present invention provides a slim bezel liquid crystal display device, which includes a rear enclosure, a front enclosure mating the rear enclosure, and a liquid crystal display module arranged inside the rear enclosure. The rear enclosure forms a retention plate. The retention plate functions to retain a lower end of the liquid crystal display module so as to fix the liquid crystal display module in the rear enclosure. The slim bezel liquid crystal display device uses an inverted L-shaped retention plate mounted at a lower end portion of a rear enclosure to retain a liquid crystal display module in position so as to fix the liquid crystal display module in the rear enclosure. The structure is simple and assembling is easy so as to effectively achieve bezel slimming and device thinning of a liquid crystal display device. | 04-17-2014 |
20140069331 | MASK AND MANUFACTURING METHOD THEREOF - A mask disclosed in the present invention includes: a first sub-mask and one side edge thereof includes a first structure; a second sub-mask and one side edge thereof includes a second structure; the first sub-mask and the second sub-mask are disposed in parallel and arranged together, and the first sub-mask and the second sub-mask are on the same plane, and the first structure and the second structure are structures complementary to each other. The present invention also discloses a mask manufacturing method. The present invention can achieve a large size mask. | 03-13-2014 |
20130128177 | Frame Type Backplane, Backlight Module, and LCD Device - The present invention discloses a frame type backplane, a backlight module, and an LCD device. The frame type backplane comprises a frame, and the frame comprises multiple mutually joined brackets. Each bracket is provided with a solid stiffener in the joining position. By research, the inventor finds that: in the backplane formed by joining brackets, when the backplane produces buckling stress, the stress is collected in the joining position of each the bracket. Therefore, the buckling deformation of the backplane usually appears in the joining positions. Because the present invention is provided with solid stiffener(s) in the joining position of two brackets, the bend resistance capacity of the joining position is improved, and then the strength of the whole backplane is improved. | 05-23-2013 |
