specific Embodiment approach 1

[0018] Specific Embodiment 1: Combining Figure 1 ~ Figure 3 Describe this embodiment, the segment code liquid crystal display meter with transparent window of this embodiment such as figure 1 As shown, it includes: a first display area 1, a window area 2 and a second display area 3, the window area 2 is located between the first display area 1 and the second display area 3, and the first display area is provided with The engine speed indicator grid, the second display area is provided with a vehicle speed indicator grid, of which there are 16 speed indicator grids, the value is from 0 to 8, each half speed unit is a grid, and the vehicle speed indicator grid is 24, the value is from 0 to 8. to 240, every 10 speed units is one grid.

[0019] In the segment code liquid crystal display meter with a transparent window in this embodiment, the first display area also includes a position indication indicator light, a safety belt indicator light and a left turn indicator light, and ...

specific Embodiment approach 2

[0022] Specific embodiment 2: In the segment code liquid crystal display instrument with a transparent window in this embodiment, the size of the first display area is L1, the size of the second display area is L2, and the size of the window area 2 is L3 , and satisfy L3≥L1+L2, the advantage of this design is to avoid the problem that the size of the window area 2 is too small, causing the driver to be unable to clearly see the content displayed on the TFT screen behind the window area 2.

specific Embodiment approach 3

[0023] Specific embodiment 3: The segment code liquid crystal display meter with a transparent window in this embodiment is further limited on the basis of specific embodiment 4, the size of the first display area 1 is L1, and the size of the second display area 2 The size is L2 to satisfy the condition L1=L2, and the first display area 1 and the second display area 2 are mirror-symmetrical. The advantage of this design is that the structure of the segment code liquid crystal display instrument with a transparent window in this embodiment has a symmetrical appearance. , to achieve a better aesthetic effect.

Abstract

The invention belongs to the technical field of vehicle instruments and particularly relates to a segment code liquid crystal display instrument with a transparent window. The segment code liquid crystal display instrument is to solve the problem of unclear display caused by partial overlap of double-layer screen display when an existing segment code screen is combined with a thin film transistor(TFT) liquid crystal screen. The segment code liquid crystal display instrument with the transparent window includes a first display area, a window area, and a second display area. The window area islocated between the first display area and the second display area. The first display area is provided with engine revolving speed indicator grids, a position indicator lamp, and a safety belt indicator lamp and a left-turn indicator lamp; the second display area is provided with vehicle speed indicator grids, an engine fault indicator lamp, a fog lamp and a right-turn indicator lamp; and the window area includes N*M display sub-units, the internal circuit structure is provided with two drive circuit interfaces of display and light transmission, and the light transmission mode and the displaymode can be switched. In the light transmission mode, the window area is transparent; and in the display mode, a specific pattern is displayed. The segment code liquid crystal display instrument withthe transparent window can be combined with the thin film transistor (TFT) liquid crystal display and can be applied in a vehicle instrument.

Description

technical field [0001] The invention belongs to the technical field of vehicle instruments, and in particular relates to a segment code liquid crystal display instrument with a transparent window. Background technique [0002] With the increasing intelligence and entertainment of vehicles, the segment code screen and color LCD screen combination instrument of the vehicle are developing in the direction of large screen and human-computer interaction. The segment code screen cannot display dynamic effects. If you want to realize dynamic display , TFT liquid crystal screen must be used, but the cost of TFT (Thin Film Transistor, thin film transistor) liquid crystal screen instrument is high, and the development cycle is long, which seriously affects the research and development cycle and production cost of the whole vehicle, restricting the human-computer interaction interface in the middle and low end For the application on vehicle models, the existing technology combines segm...
