Description

Technical Field

[0001] This utility model relates to the field of LCM display module technology, and in particular to an LCM display module with a central window. Background Technology

[0002] Liquid crystal displays (LCMs) have replaced traditional CRT displays due to their numerous advantages, including clear and detailed images, flicker-free operation, eye-friendly design, no radiation, low power consumption, and thinner and lighter design. In practical applications, LCMs typically require the following technologies:

[0003] 1. High-quality liquid crystal display panels, such as TFT (thin-film transistor) liquid crystal panels, can provide clear and vivid image display;

[0004] 2. Precise driving circuits, such as IC (integrated circuit) driver chips, ensure precise control of liquid crystal molecules to achieve accurate image display;

[0005] 3. A reliable backlight system, such as an LED (light-emitting diode) backlight, provides uniform and sufficient light to the LCD panel.

[0006] Existing LCM display modules typically display content uniformly across the entire screen.

[0007] However, during the implementation of the above technical solutions, at least the following technical problems were found: This single overall display mode limits its application in certain special scenarios, cannot meet diverse display needs, and is difficult to achieve precise partition control in some situations where the display effect of specific areas needs to be highlighted, such as the Onimusha random scrolling game console, thus affecting the flexibility and functionality of the display, and making it difficult to achieve multiple games on one machine to meet the needs of more users. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides an LCM central window display module, which solves the problem that the single overall display mode limits its application in certain special scenarios, cannot meet diverse display needs, and is difficult to achieve precise zoning control in some situations where the display effect of specific areas needs to be highlighted, such as the Onimusha random scrolling game console, thus affecting the flexibility and functionality of the display and making it difficult to achieve the technical problem of one machine with multiple games to meet the needs of more users.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A centrally located windowed LCM display module includes a protective frame and an outer display assembly mounted on the protective frame. The outer display assembly includes a first lower backlight panel, a first lower polarizer, a first display screen, and a first upper polarizer. The first lower backlight panel is fixedly mounted on the protective frame. A first lower polarizer for adjusting the angle of light entry is fixedly mounted above the first lower backlight panel. A first display screen for displaying content is fixedly mounted above the first lower polarizer. A first upper polarizer for adjusting the angle of light exit is fixedly mounted above the first display screen. A display window for dividing the display area is opened in the middle of the protective frame, the first lower backlight panel, the first lower polarizer, the first display screen, and the first upper polarizer.

[0011] Preferably, the interior of the display window is equipped with an inner display assembly, which includes a second lower backlight panel, a second lower polarizer, a second display screen, and a second upper polarizer.

[0012] Preferably, the second lower backlight panel is fixedly installed above the protective frame.

[0013] Preferably, a second lower polarizer for adjusting the angle of light entry is fixedly installed above the second lower backlight panel.

[0014] Preferably, a second display screen for displaying content is fixedly installed above the second lower polarizer.

[0015] Preferably, a second upper polarizer for adjusting the angle of light emission is fixedly installed on the second display screen.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Because display windows are opened on the protective frame, the first lower backlight panel, the first lower polarizer, the first display screen, and the first upper polarizer, no further display will be performed in the area where the display windows are opened. Therefore, the outer display component and the inner display component are independent of each other and can be controlled separately. This allows the inner and outer parts of the display module to be divided into two independent display areas, the middle and the outer perimeter, achieving a screen-within-a-screen display effect. This improves the flexibility and functionality of the display, thus meeting the needs of more users.

[0018] Second, this display module has a simple structure, low production cost, and is easy to manufacture, which helps to promote its rapid use. Attached Figure Description

[0025] This application provides a display module with a central window in the LCM (Limited-Mount Display), effectively solving the problem that the single overall display mode limits its application in certain special scenarios, fails to meet diverse display needs, and is difficult to precisely control in some situations where specific areas need to be highlighted, such as the Onimusha random scrolling game console. This affects the flexibility and functionality of the display, making it difficult to achieve the technical problem of one machine with multiple games to meet the needs of more users. Because display windows are opened on the protective frame, the first lower backlight panel, the first lower polarizer, the first display screen, and the first upper polarizer, no display will be displayed in the area where the display window is opened. Therefore, the outer and inner display components are independent of each other and can be controlled separately. This allows the display module to be divided into two independent display areas, the middle and the outer perimeter, achieving a screen-within-a-screen display effect. This improves the flexibility and functionality of the display to meet the needs of more users. This display module has a simple structure, low production cost, and is easy to manufacture, which helps to promote its use quickly.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the problem that this single overall display mode limits its application in certain special scenarios, cannot meet diverse display needs, and is difficult to achieve precise zoning control in some situations that require highlighting the display effect of specific areas, such as the Onimusha random scrolling game console. This affects the flexibility and functionality of the display, making it difficult to achieve the technical problem of one machine with multiple games to meet the needs of more users. The overall idea is as follows:

[0028] To address the problems existing in the prior art, this utility model provides a display module with a centrally located window in the LCM, including a protective frame 1. An outer display component is installed on the protective frame 1. The outer display component includes a first lower backlight 2, a first lower polarizer 3, a first display screen 4, and a first upper polarizer 5. The first lower backlight 2 is fixedly installed on the protective frame 1. A first lower polarizer 3 for adjusting the angle of light entry is fixedly installed above the first lower backlight 2. A first display screen 4 for displaying content is fixedly installed above the first lower polarizer 3. A first upper polarizer 5 for adjusting the angle of light exit is fixedly installed above the first display screen 4. A display window 6 for dividing the display area is opened in the middle of the protective frame 1, the first lower backlight 2, the first lower polarizer 3, the first display screen 4, and the first upper polarizer 5.

[0029] In summary, since display windows 6 are opened on the protective frame 1, the first lower backlight panel 2, the first lower polarizer 3, the first display screen 4, and the first upper polarizer 5, no further display will be performed in the area where display windows 6 are opened.

[0030] The inner display assembly is installed inside the display window 6. The inner display assembly includes a second lower backlight panel 7, a second lower polarizer 8, a second display screen 9, and a second upper polarizer 11. The second lower backlight panel 7 is fixedly installed above the protective frame 1. A second lower polarizer 8 for adjusting the angle of light entry is fixedly installed above the second lower backlight panel 7. A second display screen 9 for displaying content is fixedly installed above the second lower polarizer 8. A second upper polarizer 11 for adjusting the angle of light exit is fixedly installed on the second display screen 9.

[0031] In summary, the inner and outer display components installed independently inside the display window 6 are independent of each other and can therefore be controlled separately. This allows the display module to be divided into two independent display areas, the middle and the outer perimeter, thus achieving a screen-within-a-screen display effect.

[0032] Working principle:

[0033] In the first step, when in use, the first lower backlight panel 2 will emit light after being powered on. The light will then pass through the first lower polarizer 3. When the light passes through the first lower polarizer 3, it can block stray light from non-specific directions, reduce the interference of background light, and control the polarization direction of the light entering the first display screen 4. When the light passes through the first display screen 4, it will pass through or be blocked in a predetermined manner to form an image. The first upper polarizer 5 can filter out some interfering light when the ambient light is strong, making the content of the display screen easier to view. At the same time, since the protective frame 1, the first lower backlight panel 2, the first lower polarizer 3, the first display screen 4 and the first upper polarizer 5 have display windows 6, the area where the display windows 6 are opened will no longer be displayed.

[0034] In the second step, after the second lower backlight panel 7 inside the display window 6 is powered on, it will emit light. Then the light will pass through the second lower polarizer 8. When the light passes through the second lower polarizer 8, it can block stray light from non-specific directions, reduce the interference of background light, and control the polarization direction of the light entering the second display screen 9. When the light passes through the second display screen 9, it will pass through or be blocked in a predetermined manner, thereby forming an image. The second upper polarizer 11 can filter out some interfering light when the ambient light is strong, making the content of the display screen easier to view. Since the outer display component and the inner display component are independent of each other, they can be controlled separately, so that the inner and outer parts of this display module can be divided into two independent display areas, the middle and the outer perimeter, thereby achieving the display effect of a screen within a screen.

[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
