specific Embodiment approach 1

[0027] Specific implementation mode one: combine figure 1 To describe this embodiment,

[0028] The segment code screen color display device of the automobile instrument panel includes: segment code screen 1, UV printed color film 2, color liquid crystal screen 3, light guide bracket 4, instrument PCB board 5; color liquid crystal screen 3 can be an LCD liquid crystal screen (STN liquid crystal screen, TFT LCD screen), OLED LCD screen or LTPS LCD screen, etc.

[0029] The segment code screen 1 is set on the uppermost layer (the outermost layer), starting from the segment code screen, and from the upper layer to the lower layer, there are UV printed color film 2, color LCD screen 3, light guide bracket 4, and instrument PCB board 5, namely The bottom of the segment code screen 1 (the surface facing the color LCD screen) is closely attached to the UV printed color film 2, and the color LCD screen 3 is arranged under the color film 2. The area of ​​the liquid crystal display are...

specific Embodiment approach 2

[0034] The color film 2 in this embodiment includes a substrate and a color light-transmitting area and a black light-blocking area printed on the surface of the substrate, and the substrate is a white film made of pc (polycarbonate) material; that is, made of pc material The white film is used as the substrate, and the surface of the substrate is printed with a colored light-transmitting area and a black light-blocking area; the colored light-transmitting area is an area formed by printing a corresponding shape and color at a corresponding position according to the UI design. The black light-blocking area is the area that is printed into the corresponding shape and formed in black. After testing, it has been proved that UV printing on pc material has good stability, can adapt to the working conditions of automobile instruments, and can serve for a long time without fading or color cast, thus ensuring the display effect and service life of automobile instrument panels. .

specific Embodiment approach 3

[0036] The thickness of the color film 2 in this embodiment is 0.125mm-0.175mm. If the color film is too thick, it will affect the light transmittance of the light source below, which will cause the display of the segment code screen to be dark; if the color film is too thin, it will cause excessive light transmittance, which will cause the color display under the segment code screen or the color film of the color film to appear in the visual effect. The color of the light-transmitting area becomes lighter, which reduces the contrast and affects the display effect; and the color film is too thin, the color film is too soft, and it is difficult to fit closely under the segment code screen, and even creases are generated, which cannot be completely fitted with the segment code screen. It may cause light leakage and reduce the yield.

[0037] Other structures and parameters are the same as in the first or second embodiment.

Abstract

The invention provides an automobile instrument panel segment code screen color display device, production method and display method, and relates to the field of automobile instrument panel liquid crystal screens. In order to solve the problem that an existing segment screen display cannot realize a color gradation effect and the display is darker. A segment code screen of the device is arranged on the uppermost layer, a color film printed by UV is stuck below the segment code screen, and a color liquid crystal screen is arranged below the color film; the center of the color film printed by the UV is provided with a liquid crystal screen display port, the liquid crystal screen display port and a liquid crystal display area of a color liquid crystal screen have same sizes and correspondinglocations; the color film around the liquid crystal screen display port is provided with a color light transmission area, and areas except the color light transmission area are black light blocking areas; a liquid crystal screen assembly is arranged on a light guiding bracket, an instrument PCB board is arranged under the light guiding bracket; an LED light source is arranged on the instrument PCBboard, a light guiding hole is formed in the light guiding bracket, and the positions of the LED light source, light guiding hole corresponds to color light transmission area of the color film. The automobile instrument panel segment code screen color display device, production method and display method are suitable for the production of automobile instrument panels.

Description

technical field [0001] The invention relates to the field of liquid crystal screens of automobile dashboards, in particular to a segment code screen color display device and a color display method. Background technique [0002] At present, automotive instruments using segment code screens have appeared. This type of automotive instrument is composed of a light shield, a light shield, a segment code screen, a color liquid crystal display, a light guide bracket, a PCB circuit board, and a bottom case. In order to enable the upper segment code screen (the segment code screen area outside the color LCD display) to be displayed in color, the technology of setting a screen printing plate (screen printing plate) between the segment code screen and the color LCD display has appeared. The color pattern of the screen printing plate is displayed in color through the segment code screen through the bottom light source, the patent of "a color display device for automobile instrument pane...
