Embodiment Construction

[0023] Embodiments of the invention are discussed in detail below. It should be appreciated, however, that the embodiments provide many applicable concepts that can be implemented in a wide variety of specific contexts. The discussed and disclosed embodiments are for illustration only and are not intended to limit the scope of the present invention.

[0024] Please refer to figure 1 , which shows a schematic diagram of the display device 100 according to an embodiment of the present invention. The display device 100 includes a display panel 110 , a source driver 120 and gate drivers 130A, 130B. The display panel 110 has a plurality of pixels arranged in an array, which are commonly used to display images. The display panel 110 may be, for example, a twisted nematic (TN) type, an in-plane switching (IPS) type, a fringe-field switching (FFS) type, or a vertical alignment (VA) type. Various types of liquid crystal display panels, or organic light-emitting diode (OLED) panels,...

Abstract

The invention discloses a shift register and a display device. The shift register comprises a pre-charging unit, a pull-up unit, a first pull-down unit, and a second pull-down unit. The pre-charging unit receives a first input signal and a second input signal, and outputs a pre-charging signal via a first node. The pull-up unit receives the pre-charging signal, a first clock signal and a second clock signal, and outputs a scanning signal via a second node. The first pull-down unit receives the pre-charging signal, a first pull-down control signal and a second pull-down control signal, and controls whether to pull down the scanning signal to a reference level. The second pull-down unit receives the pre-charging signal, the first pull-down control signal and the second pull-down control signal, and controls whether to pull down the scanning signal to the reference level. The shift register of the invention is of high reliability and high stability. Moreover, the display quality of the display device comprising the shift register is improved.

Description

technical field [0001] The invention relates to a shift register, and in particular to a shift register capable of improving reliability and a display device with the shift register. Background technique [0002] With the continuous advancement of thin film transistor (TFT) liquid crystal display technology, the technology of integrating the driving circuit on the display panel, such as system on glass (SOG), has gradually been widely used in today's display on the device product. On the other hand, for high-resolution display devices, the driving time of each pixel is limited. If the driving circuit cannot complete the driving of the corresponding pixel within the driving time, it may cause image display error data or other factors due to poor driving stability. problems caused by good. Therefore, how to design a driving circuit suitable for a high-resolution display device has become one of the goals of the industry. Contents of the invention [0003] The purpose of t...
