The support plate 6 has a mounting plate surface, and the mounting plate surface has a curved area, the size, position and curvature of which are set as needed. The Mini-LED flexible lamp strip 5 is fully attached to the mounting plate surface of the support plate 6. Since the Mini-LED flexible lamp strip 5 is flexible and can be bent, the Mini-LED flexible lamp strip 5 can adapt to the shape of the mounting plate surface of the support plate 6, that is, the mounting plate surface of the support plate 6 has a curved area, and the Mini-LED flexible lamp strip 5 is curved at the curved area. If the support plate 6 has a straight area, the Mini-LED flexible lamp strip 5 is flat at the straight area.

[0041] Example 2

[0042] This embodiment provides a curved straight-screen display, such as Figures 1 to 6 As shown, the display includes a touch cover, a light board (as in Embodiment 1), a PCB driver board 7, and a rear cover 8 arranged sequentially. The touch cover and the light board are fully bonded together, with the Mini-LED flexible light strip 5 of the light board facing the touch cover and the support plate 6 of the light board facing the PCB driver board 7. The PCB driver board 7 is electrically connected to both the Mini-LED flexible light strip 5 and the touch cover. The touch cover and the light board together form the display module. This curved direct-view screen can be used in various scenarios, such as in-vehicle displays, offering a more dazzling effect, embellishing the intelligent cockpit of automobiles, and creating a greater sense of ceremony and atmosphere. Adopting a Mini direct-view method, it offers better cost-effectiveness compared to OLED, improving the visual effect while maintaining cost advantages, providing more solutions for the diversification of intelligent cockpit displays. Note: PCB stands for Printed Circuit Board.

[0043] In one implementation, such as Figures 1 to 6 As shown, the touch cover includes a front cover 1, a color film 2, and a touch film 3 that are sequentially bonded together. The touch film 3 faces the Mini-LED flexible light strip 5 and is electrically connected to the PCB driver board 7. The front cover 1 is a transparent plate.

[0044] In one implementation, such as Figures 1 to 6 As shown, the transparent panel (front cover 1) is a glass panel. The glass panel is formed using a hot bending process.

[0045] In one implementation, such as Figures 1 to 6 As shown, the front cover 1, the color filter 2, and the touch film 3 are bonded together with optical adhesive. OCA (Optically Clear Adhesive) can be used as the optical adhesive. Note: OCA stands for Optically Clear Adhesive.

[0051] In one implementation, such as Figures 1 to 6 As shown, the Mini-LED flexible light strip 5 includes a flexible circuit board and Mini-LED lights. The Mini-LED lights are mounted on the flexible circuit board. The Mini-LED lights adopt a one-light-one-driver approach, that is, each LED light is controlled individually. Of course, this driving method is a reference method and can be adjusted according to the actual situation. For example, in order to reduce costs and sacrifice the display effect by rotating, two lights can be driven by one driver or four lights can be driven by one driver.

[0052] In one implementation, such as Figures 1 to 6 As shown, the Mini-LED light spacing (pitch) is 0.7mm, which allows for clearer display. This 0.7mm spacing is the optimal minimum spacing given the combined constraints of the Mini-LED's size and wiring space; therefore, further reducing the spacing is not recommended. Of course, this value is for reference only and can be adjusted according to actual conditions.

[0053] In one implementation, such as Figures 1 to 6 As shown, the Mini-LED flexible light strip 5 uses different proportions of PWM to display different colors, thus forming a display interface.
