Description

TFT display screen and integrative display system

Technical Field

The utility model relates to a liquid crystal display technical field especially relates to a TFT display screen and integrative display system.

Background

At present, the electronic Display technology, especially the LCD (Liquid Crystal Display) Display and the OLED (Organic Light-Emitting Diode) Display are mainly used as screens on electronic devices, and the LED Display (backlight LCD using LEDs as Light-Emitting elements) still belongs to the LCD Display. The development of LCD displays is mature, including TFT, VA and other types of LCD displays, especially TFT displays, which are low in cost and stable in light emission, and the backlight lamps at Black-light position are modulated by the liquid crystal layer at the front panel portion to display images, and each liquid crystal pixel on the display is driven by a thin film transistor integrated behind the pixel, so the TFT display is an active matrix liquid crystal display device.

TFT display screen when using, can set up a panel at the front end of display screen usually, for example glass or organic glass form display panel, protect the display screen module on the one hand, form sealedly, on the other hand can also set up touch, display lamp or other functional design on the panel, realizes the function integration. In some occasions, people hope that the panel is black or full black, the display is attractive and high-grade customized display, so that the display screen is hoped to have full black effect when being extinguished, the integral full black effect can be realized under the condition of being lightened, the embedding of the frame of the display screen and the panel is not hoped to be seen, but the realization is difficult at present, for example, in the realization process of the TFT display screen, due to the backlight display mode of the TFT, a liquid crystal layer cannot be completely closed, when the TFT displays black, partial light can penetrate through a color layer, so that the black displayed by the TFT display screen is actually dark gray mixed with white and black, when the ambient light is darker, the pure black display effect is difficult to be presented, particularly, in the state that the display screen is bright, the display screen profile which cannot be input with the panel can be displayed, the display effect is influenced, and meanwhile, in the condition that the profile display screen is more obvious. Therefore, if the panel is pure black, the display effect is poor, whether the screen is bright or dark.

In the prior art, an OLED display screen is used as a display module, the display principle of the OLED display screen is different from that of LCD display, when the display screen is turned off, black displayed by the OLED is a pixel point of a black area, so that a pure black display effect is achieved, but the cost of the OLED display screen is very high and is 2-3 times that of a TFT display screen with the same size, the preparation process is complex, meanwhile, due to the fact that light attenuation exists in a lamp, the service life of the OLED display screen is shorter than that of the TFT display screen, and the response speed of the STN display screen adopted in the prior art is lower and is 200 milliseconds.
