Description

Segment display screen and its manufacturing method, automotive dashboard display device and its display method Technical Field

[0001] This invention relates to a segment code screen and its manufacturing method, and an automotive dashboard display device and its display method, belonging to the field of automotive dashboard displays. Background Technology

[0002] In recent years, segment display technology has been continuously developing. Since the advent of the segment display plus color screen structure, segment displays have gained more display options, enabling them to display grayscale and gradient colors. The gradient color display principle of segment displays involves adding a colored film between the segment display and the LED backlight. Gradient color effects are printed on this colored film. The ink used for printing has a certain degree of light transmittance. When the LED shines on the colored film, the final mixed gradient color can be seen through the window display area of ​​the segment display. In product design, many design effects involve a gradual transition from one color to the cover color, making the overall effect of the segment display look like an LCD screen and avoiding abrupt color differences at the segment boundaries.

[0003] As users' aesthetic standards rise, the screens of their electronic devices are becoming increasingly larger, and users expect their cars to have more advanced and technologically advanced electronic equipment. However, due to cost considerations, the overall cost of a fully digital instrument cluster is far greater than that of a segment display. Using two segment displays plus a dot-matrix LCD can achieve a similar consistency to a fully digital display, leading to a proliferation of segment display designs. However, uneven color transitions in a segment display are easily noticeable to users, negatively impacting the user experience. Furthermore, the actual display effect of segment displays cannot achieve perfect color transitions because the ink on the colored film has a certain degree of light transmittance. Under LED illumination, the ink displays a color cast, resulting in noticeable color differences at the edges and an overall poor visual effect.

[0004] In summary, the actual display effect of segment display screens in combination with color films has technical problems such as obvious boundary color difference and poor overall visual effect. Summary of the Invention

[0005] This invention addresses the technical problem of significant boundary color differences and poor overall visual effect in the actual display of segment code screens when combined with color films, and proposes a segment code screen display device and display method for automotive dashboards.

[0006] The technical solution of the present invention is that the segment code screen body is installed in an external car dashboard display device. A gradient ink layer printed by UV is processed at the window boundary on the back of the segment code screen body. The ink amount of the gradient ink layer gradually decreases along the inner ring to the outer ring of the car dashboard. The shape of the gradient ink layer is the same as the window boundary on the back of the segment code screen body.

[0007] As another improvement of the present invention, a method for manufacturing a segment code screen includes the following steps:

[0008] Step 1: Assemble the standard segment code screen, color film, printed circuit board bracket and printed circuit board, and light up the LED light source of the printed circuit board to obtain the actual color effect at the window boundary of the standard segment code screen;

[0009] Step 2: Design the UV printing drawing of the segment code screen body. Use a video camera to take pictures of the actual color effect at the window boundary of the conventional segment code screen in Step 1. Determine the gradient color range and complementary color value through image recognition. Write software code to make the computer draw the UV printing drawing of the entire gradient color range.

[0010] Step 3: Position and calibrate the standard segment code screen. According to the UV printing drawing of the segment code screen body designed in Step 2, use a UV printer to print a layer of gradient ink on the back of the standard segment code screen to initially complete the manufacturing of the segment code screen body.

[0011] Step 4: Assemble the segment display body, color film, printed circuit board bracket and printed circuit board, turn on the LED light source of the printed circuit board, observe whether the ink range of UV printing meets the design requirements, make optimization and adjustment, and achieve the target effect of color gradient and uniform color transition at the window boundary of the segment display body.

[0012] As another improvement of the present invention, step two includes the following steps:

[0013] Step 1: Use a video camera to capture the actual color effect at the window boundary of the regular segment code screen body in Step 1, convert the size of the gradient color area from area to the length of a single line, and determine the length of the single line through image recognition.

[0014] Step 2: By identifying the gradient color value at the window of the segment code screen body and the color value of the adjacent position at the unwindowed part of the segment code screen body through image recognition, the complementary color value for UV printing is calculated using the color addition formula, and the color error caused by image recognition is corrected to determine the final complementary color value for UV printing.

[0015] Step 3: Write software code to enable the computer to draw UV printing drawings covering the entire gradient color range.

[0016] As another improvement of the present invention, an automotive dashboard display device includes, from top to bottom, a screen ring, a segment code screen body, a color film, a printed circuit board bracket, a printed circuit board, and an instrument panel base. The segment code screen body and the color film are the same size. An LED light source is provided on the printed circuit board. A gradient ink layer printed by UV is processed at the window boundary on the back of the segment code screen body. The ink volume of the gradient ink layer gradually decreases along the inner ring to the outer ring of the automotive dashboard. The shape of the gradient ink layer is the same as the window boundary on the back of the segment code screen body.

[0017] As another improvement of the present invention, the width of the gradient ink layer along the inner to outer ring direction of the car dashboard is a, and the transparency of the gradient ink layer along the inner to outer ring direction of the car dashboard from the starting position to the a / 12 position is 100%.

[0018] As another improvement of the present invention, the width of the gradient ink layer along the inner to outer ring of the car dashboard is uniformly reduced from 100% to 0% from position a / 12 to position a / 3.

[0019] As another improvement of the present invention, the thickness of the colored film is 0.13mm-0.17mm.

[0020] As another improvement of the present invention, a method for displaying an automotive dashboard display device includes the following steps:

[0021] Step 1: Print a gradient pattern area on the colored film;

[0022] Step 2: A gradient ink layer printed with UV ink is processed at the window boundary on the back of the segment code screen;

[0023] Step 3: Light up the LED light source on the printed circuit board, control the area on the segment display that corresponds to the color film to transmit light according to the set pattern shape, and at the same time ensure that the size of the pattern area on the color film is larger than the size of the pattern area on the segment display, so as to display the set pattern shape on the segment display.
