Description

Color film substrate and liquid crystal panel with good imaging effect of camera under screen

Technical Field

The utility model belongs to the technical field of display panel's the manufacturing, specifically indicate an effectual various membrane base plate and liquid crystal display panel of camera formation of image under messenger's screen.

Background

With the continuous development of electronic technology, cameras are applied more and more widely in various electronic devices. However, the camera is not consistent with the appearance of the surrounding environment, and is easy to observe, which greatly affects the beauty of the electronic equipment. To solve this problem, off-screen cameras have come to work. The under-screen camera is to place the camera 200 under the liquid crystal display 100, as shown in fig. 1, which can greatly improve the aesthetic property of the electronic device and increase the degree of freedom of the placement position of the camera.

The basic structure of the lcd device includes an lcd panel, an ic (source driver, drain driver), a flexible printed circuit board, and a backlight module. The backlight module further comprises a light source, a light guide plate, a diffusion sheet, a brightness enhancement sheet, a back plate and other components. With the development of liquid crystal display technology, especially the development of full-screen technology, most manufacturers currently install an inward opening in the backlight module of the display device to allow the camera under the screen to be placed correspondingly, and thus receive incident light from the external environment.

However, the transmittance of the conventional liquid crystal display is low, and the imaging quality of the under-screen camera is greatly influenced by diffraction caused by periodic arrangement.

SUMMERY OF THE UTILITY MODEL

The utility model discloses one of the technical problem that will solve lies in providing a make under the screen camera effectual various membrane base plate of formation of image.

The second technical problem to be solved of the utility model is to provide a make effectual liquid crystal display panel of camera formation of image under the screen.

The utility model discloses a realize like this:

a color film substrate enabling an under-screen camera to have a good imaging effect comprises: the color filter comprises a glass substrate, and a black matrix line, a color resistance layer and a flat layer which are arranged on the glass substrate; the method is characterized in that: the color resistance layer of the area corresponding to the camera under the screen is made of electrochromic materials, a first transparent electrode layer is arranged below the color resistance layer of the electrochromic materials, and a second transparent electrode layer is arranged above the color resistance layer of the electrochromic materials and the black matrix line of the area corresponding to the camera under the screen.

Furthermore, the first transparent electrode layer and the second transparent electrode layer are both ITO transparent electrode layers.

A liquid crystal panel comprises the color film substrate which enables an under-screen camera to have a good imaging effect.

The utility model has the advantages of: the design of two color resistance materials is provided, the color resistance material in the area of the camera under the screen is designed into an electrochromic RGB color resistance material, and the other areas keep the traditional color resistance material. The two layers of transparent electrodes and the middle electrochromic material are designed in the area of the camera under the screen, when the electrodes are powered on, the electrochromic layer can be changed into an RGB display picture, and when the electrodes are not powered on, the electrochromic layer is in a transparent state, so that the high transmittance of the camera under the screen is realized, the better imaging quality of the camera under the screen is achieved, and better equipment use experience is brought to a user.

Drawings

The invention will be further described with reference to the following examples with reference to the accompanying drawings.

Fig. 1 is a schematic view of the overall structure of a screen provided with an off-screen camera.

Fig. 2 is the utility model discloses the regional various membrane base plate structure schematic diagram of camera under the non-screen.

Detailed Description

A CF (color filter) color filter in a TFT-LCD panel is composed of a plurality of pixels arranged in a matrix, each pixel is composed of three sub-pixels of red (R), green (G), and blue (B), and a black matrix (BlackMatrix) is generally used for separation in order to prevent color mixing of the sub-pixels.

As shown in fig. 2 and fig. 3, the present embodiment provides a color film substrate for making an imaging effect of an off-screen camera good, including: a glass substrate 101, and a black matrix line 102, a color resist layer 103 and a flat layer 104 which are arranged on the glass substrate 101; the color resistance layer 103 of the area corresponding to the camera under the screen is made of electrochromic materials, a first ITO (indium tin oxide) transparent electrode layer 105 is arranged below each RGB electrochromic material color resistance layer, and a second ITO transparent electrode layer 105 is arranged above the electrochromic material color resistance layer 103 and the black matrix line of the area corresponding to the camera under the screen.

The utility model also provides a liquid crystal display panel, include as above various membrane base plate.

The utility model provides a design of two kinds of look resistance materials, the regional look resistance material design of camera is electrochromic RGB look resistance material under the screen, and other regions keep traditional look resistance material. Two layers of transparent electrodes and a middle electrochromic material are designed in the area of the camera under the screen, when the electrodes are electrified, the electrochromic layer can be changed into an RGB display picture, and when the electrodes are not electrified, the electrochromic layer is in a transparent state, so that the high transmittance of the camera under the screen is realized, the better imaging quality of the camera under the screen is achieved, and better equipment use experience is brought to a user.
