Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0015] The display device provided by the embodiment of the present invention includes LCD, OLED (Organic Light Emitting Diode, Organic Light Emitting Diode Display) and other display devices. Taking a liquid crystal display device as an example, the liquid crystal display device includes a liquid crystal display panel and is bound to the liquid crystal display panel. A flexible circuit board, wherein the liquid crystal display panel includes an opposing TFT (Thin Film Transistor, thin film transistor) array substr...

Abstract

The invention discloses a display device which comprises a first display test signal input portion used for inputting first display test signals, a first display test signal control portion used for controlling input of the first display test signals, a second first display test signal input portion used for inputting second display test signals, a first test bus connected with the first display test signal input portion and a second test bus connected with the second display test signal input portion. The first test bus is connected with the second test bus. According to the display device, influences of direct current residual caused by the photovoltaic effect of a drive integrated circuit or an amorphous silicon thin film transistor on the display effect can be reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] In recent years, liquid crystal display (LCD for short) products have developed very rapidly, and more and more high-quality liquid crystal displays are gradually launched into the market, and their application fields are constantly expanding. [0003] The basic principle of the liquid crystal display screen is: by applying different voltages between the two polar plates of the liquid crystal, the liquid crystal is deflected at a certain angle to allow light to pass through. The size of the liquid crystal deflection angle determines the light transmittance of the liquid crystal, thereby producing different grays. degree display. [0004] However, in the liquid crystal display process, the voltage of the common electrode is fixed, and the liquid crystal layer is equivalent to a capacitor on the circuit. When the driver int...
