Display device

Abstract

The invention provides a displayer. In the case where one horizontal period becomes shorter as a high frame rate drive of 120 Hz or higher is introduced or the resolution is increased, the time for the writing in of a voltage to the holding capacitor of pixels cannot be sufficiently secured. Two data lines are provided to an electrode for supplying a data voltage to a group of pixels in the vertical direction in such a manner that one data line of the two data lines is connected to one of the two pixels in the vertical direction and the other data line of the two data lines is connected to the other pixel, while one gate line shared by two horizontal lines formed of two pixels, to which different data lines adjacent in the vertical direction are connected, is provided and connected to the electrode for controlling the turning ON / OFF, the data line driving portion has outputs of which the number is two times greater than the number of horizontal pixels in order to make it possible to apply a voltage simultaneously to the pixels for two horizontal lines, and the gate line driving portion has outputs of which the number if 1 / 2 the number of vertical pixels by connecting one gate line to two horizontal lines.

Description

technical field [0001] The present invention relates to an active matrix display device and a driving method thereof, in particular to a liquid crystal display and the like. Background technique [0002] The active matrix liquid crystal display device is used as a display device such as a thin TV because of its thin profile, high definition, and low power consumption. [0003] Figure 16 (a) shows a configuration example of a conventional liquid crystal display device. A conventional liquid crystal display device is composed of a liquid crystal panel unit 1600 , a data line driving unit 1601 , a gate line driving unit 1602 , and a timing control unit 1603 . The liquid crystal panel unit 1600 includes active elements such as thin film transistors (Thin Film Transistor, hereinafter referred to as TFT) in pixels 1604 arranged in a matrix of n×m in plan. Figure 17 A detailed view showing the pixel 1604 arrangement. The electrodes for controlling on / off of each active element...

Problems solved by technology

[0011] In the above-mentioned background technology, due to the high frame rate drive of high-speed screen rewriting at 120 Hz or higher, which can effectively improve the blurring of moving images, and the high resolution of the panel, the horizontal period for scanning one line is shortened, or it is not possible to ensure sufficient image quality. During the writing period in which the voltage corresponding to the display data is applied to the pixel electrode, the required voltage cannot be written into the pixel electrode, which may lead to a decrease in image quality
