Description
Technical Field
The invention relates to the technical field of TFT display, in particular to a bright-screen integrated black display panel based on local TFT display and a preparation method thereof.
Background
Currently, 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 type liquid crystal Display 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 light emitted by the Back-light position is modulated by the liquid crystal layer of 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 cases, people want the panel to be black or full black, and the customized display is beautiful and high-grade, so it is hoped that the display screen can realize full black effect when it is off, and can realize integral full black effect when it is on, but it is not hoped to see the jogged frame of the display screen and the panel, but it is difficult to realize at present, for example, in the realization process of using the TFT display screen, because of the backlight display mode of the TFT, the liquid crystal layer can not be completely closed, when the TFT displays black, there is part of light to transmit the color layer, so that the black displayed by the TFT display screen is actually the dark gray mixed with white and black, when the ambient light is darker, it is difficult to present the real effect of pure black, especially in the bright screen state of the display screen, the outline of the display screen which can not be inputted with the panel lattice can be displayed, and the display effect is affected.
Meanwhile, under the condition of bright screen, the outline of the square display screen is displayed more obviously. Therefore, if the panel is black, the display effect is poor, namely, the screen is bright or dark.
Still adopt the OLED display screen as the display module assembly among the prior art, because the display principle of OLED display screen is different from the LCD demonstration, when the screen is worried about, the black that OLED shows is the pixel point of directly closing the black region, reaches pure black display effect, but the cost of OLED display screen is very high, is 2~3 times of the TFT display screen of the same size, and preparation technology is complicated, simultaneously because there is the light decay in the lamp, life is than in the TFT display screen than comparatively poor.

In addition, some aspects of the present disclosure may be used alone, or in any suitable combination with other aspects of the present disclosure.
With reference to fig. 1 and 2, based on the prior art that a TFT display screen is used as a display module, the display effect that the display panel is black is not ideal, and particularly, a screen frame is easily formed integrally with the display panel under the condition that the TFT display screen is bright.
In connection with the bright-screen integrated black display panel 100 based on the local TFT display in the example shown in fig. 3, as a panel component in a display component of an electric appliance, a bluetooth sound box, an electronic alarm clock, and other electronic devices, a display module is formed with the TFT display screen and a driving circuit behind the panel component, and is fixed in a housing of the electronic device or the electric appliance or a dedicated housing, and a front-end display is provided when the TFT display screen emits light, wherein the TFT display screen and the driving circuit form the display component, and are fixedly combined in a manner favorable for installation and assembly.
The bright screen integrated black display panel 100 shown in the figure mainly includes a panel substrate 110 formed of a glass material, i.e., a glass panel, especially a high-transmittance class a glass panel substrate.
In alternative embodiments, the panel substrate 110 is designed in a regular shape to facilitate installation and aesthetics, such as a round panel, a square panel, or other regular polygonal panel.
In the following examples of the present invention, a circular panel is exemplified.
Referring to fig. 3, the panel substrate 110 is a circular glass with a small thickness, which may be selected from 0.5mm to 1 mm. Of course, in other embodiments, other suitable thicknesses of the glass panel substrate may be selected.
The shape structure of the panel base 110 defines a first face and a second face of its circular shape. In the following embodiments, the first surface is used as a working surface and combined with a TFT display panel. The second surface serves as a display surface facing outward. Particularly preferably, the edge of the second face is subjected to a round chamfering treatment.
The working surface of the panel base 110 defines a first region 112, a second region 114, and a third region 116, which correspond to different functions and independent light transmittances, respectively.
In the embodiment of the present invention, the first region 112 is a local display region corresponding to the TFT display, for example, in the illustration, the TFT display is a square display, which is located at the center of the panel substrate 110. In other embodiments, the TFT display screen may be designed with other suitable shapes and/or shapes.

In connection with fig. 3, the second area 114 on the display panel is arranged to have predetermined graphic patterns 114a, 114b, such as shown in fig. 3, which are used to indicate a predetermined touch function or display function, such as the timing graphic pattern on the left side in the embodiment of fig. 3, which is used to indicate a timing function. These graphic styles include, for example, icons 114a indicating function settings, and lines 114b for effect display. The touch position can be set through software by designing the touch function corresponding to different graphic styles.
In further embodiments, the graphical styles to implement the above-described functions may also be configured in other shapes and to indicate corresponding different functions.

In an alternative embodiment, a touch-sensitive TP layer may be printed on the panel substrate 110, and a touch position is provided in the second region 114, so that the printed circuit of the TP layer may be configured to be used for touch control at a position where the pattern 114a is located, so as to implement a corresponding preset function.
In an alternative embodiment, as shown in fig. 5, a double-sided adhesive layer 119a, such as a double-sided adhesive tape, is further attached to the edge of the panel base 110. One side of the adhesive tape is adhered to the panel base body 110, the other side of the adhesive tape is covered with a cover layer for covering the adhesive, and a tearing strip 119b is reserved, so that the cover layer is convenient to remove, and the panel base body is convenient to mount and assemble with a PCB control panel or other components and a shell.
