Description

Technical Field

[0001] The utility model relates to a color printing structure for a display screen, more specifically, to a color printing structure for MONO TFT. Background Art

[0002] Due to cost constraints, colored indicators are typically displayed on TN panels. With this solution, the size and position of the indicators cannot be modified; they can only be turned on or off. Therefore, the more symbols a display requires, the larger the display area required, and the more complex the color scheme and symbol layout design becomes.

[0003] Chinese patent document CN214822610U discloses an automotive instrument with dynamic indicator symbols, comprising an instrument panel, a TFT display screen, and a dynamic display area. The dynamic display area is used only to dynamically display first-category vehicle indicators. The first-category vehicle indicators include n1 indicators. The number of indicators displayed in real time on the dynamic display area is n2, where n2 < n1; or, the area of ​​the display screen required to simultaneously display all first-category indicators is m1, and the area of ​​the display screen occupied by the dynamic display area when displaying the first-category indicators in real time is m2, where m2 < m1. The TFT display screen also includes a fixed display area for displaying second-category vehicle indicators. The first-category indicators include alarm indicators. The second-category indicators include work indicators. The dynamic display area includes a single-line display area. The alarm indicators include a red alarm symbol and a yellow alarm symbol, with the red alarm symbol positioned before the yellow alarm symbol. The dynamic display area includes multiple rows of display areas, the alarm indicator symbols include a red alarm symbol and a yellow alarm symbol, the red alarm symbol and the yellow alarm symbol are arranged in separate rows, and the area required for displaying each of the first-type indicators is the same.

[0004] This patent fixes a dynamic display area on the TFT display screen to queue up and dynamically display the first-category indicators. When no error or fault occurs, the first-category indicators will not be displayed in the dynamic display area. In this way, the untriggered first-category indicators will not occupy additional display area, greatly reducing the space occupied by the first-category indicators on the TFT screen and facilitating the layout of the instrument panel. The first-category indicators on the instrument panel are mostly alarm indicators, so the dynamic display area can arrange and display these symbols for easy viewing and to avoid missing information. Obviously, this structure cannot solve the problem of existing indicator symbols being colored.

[0005] Chinese patent document CN218350649U discloses a color polarized liquid crystal display module, including an outer plastic frame, a middle plastic frame, a panel, a TFT liquid crystal module and a backlight module. The TFT liquid crystal module and the backlight module are both located inside the middle plastic frame. The middle plastic frame is located inside the outer plastic frame. The panel is arranged on the upper end surface of the TFT liquid crystal module. A first mounting groove is provided at the upper end of the inner wall of the middle plastic frame, and the bottom of the first mounting groove is bonded and fixed to the end surface of the panel. A light-shielding groove is provided on the inner wall of the middle plastic frame at a position below the first mounting groove, and the groove wall of the light-shielding groove and the end surface of the panel are bonded with light-shielding glue. A frame-shaped metal sheet is fixed to the upper end of the inner wall of the middle plastic frame. A plug-in slot is provided on the upper inner wall of the outer plastic frame. A frame-shaped card slot plate corresponding to the position of the frame-shaped metal sheet is fixed to the lower end of the groove wall of the plug-in slot. The TFT liquid crystal module includes an upper polarizer, an upper glass substrate, a color filter, a TFT plate, a lower glass substrate, and a lower polarizer. The upper polarizer is fixedly mounted on the upper end surface of the upper glass substrate, the color filter is positioned between the TFT plate and the upper glass substrate, the lower glass substrate is positioned at the lower end of the TFT plate, and the lower polarizer is fixedly mounted at the lower end of the lower glass substrate. A second mounting groove is defined on the inner wall of the middle plastic frame below the light-shielding groove. The outer edges of the upper and lower glass substrates extend into the interior of the second mounting groove and are fixed thereto. A light-shielding frame is fixedly mounted between the upper and lower glass substrates in the second mounting groove, and the color filter and TFT are both fixedly mounted within the light-shielding frame. A third mounting groove is defined on the lower end of the inner wall of the middle plastic frame, and the lower polarizer is fixedly mounted within the third mounting groove. Foam adhesive is fixedly mounted between the bottom of the third mounting groove and the lower polarizer. A frame-shaped elastic pad is fixedly installed between the inner wall of the frame-shaped metal sheet and the side wall of the middle rubber frame. The cross-section of the frame-shaped elastic pad is triangular. The upper end of the middle rubber frame and the side wall of the frame-shaped metal sheet are coated with an adhesive layer and fixedly bonded to the slot wall of the plug-in slot through the adhesive layer.

[0006] This patent utilizes the outer and middle plastic frames, the TFT liquid crystal module, and the backlight module to coordinate with each other, allowing the TFT liquid crystal module to function as a color polarized liquid crystal display module. The coordination of the first mounting slot, the light shielding slot, and the light shielding adhesive provides stable support for the panel, preventing light leakage from gaps caused by external forces. This reduces the impact of external forces squeezing the TFT liquid crystal module and backlight module, thereby reducing the possibility of damage to the liquid crystal display module. Obviously, this structure cannot solve the problem of existing indicator symbols being colored. Utility Model Content

A polarizer 2 is disposed on the lower surface of the MONO TFT body 1. The polarizer 2 is provided with a blue silk-screened area 21, a green silk-screened area 22, and a red silk-screened area 23. The sizes of the blue silk-screened area 21, the green silk-screened area 22, and the red silk-screened area 23 are adapted to the size of a display symbol 3. The blue silk-screened area 21, the green silk-screened area 22, and the red silk-screened area 23 are rectangular.

[0033] With this structural design, the polarizer 2 can be configured with different blue, green, and red silk-screened areas 21, 22, and 23, depending on the position and size of the display symbol 3. Unprinted areas remain displayed in black and white. When the display symbol 3 is illuminated, it displays different colors, resulting in excellent results and low cost.
