Description

Technical Field

[0001] The utility model relates to display technology, in particular to a laminating and alignment structure of a color segment code screen. Background Art

[0002] Instruments and other display devices usually use segment code screens to provide display functions because the display pattern is fixed. In order to achieve color display of the segment code screen at a low cost, Figure 1 and 2 As shown, a color segment code screen is usually realized by laminating a color film 2' on a black and white segment code screen 1', and a segment code block in the color film 2' corresponds to a display segment code in the black and white segment code screen 1'.

[0003] In order to achieve alignment and bonding between the color film 2' and the segment code screen, two lugs 21' are designed on the edge of the color film 2'. During bonding, the bonding jig limits the color film 2' through the positioning grooves corresponding to the lugs 21', thereby limiting the relative position between the color film 2' and the segment code screen.

[0004] However, after the color film 2' and the segment code screen are relatively fitted, the two lugs 21' on the color film 2' are beyond the edge of the segment code screen, which will interfere with other components of the whole machine, such as the casing, in the subsequent whole machine assembly process, affecting the assembly efficiency of the whole machine. Utility Model Content

[0005] In order to solve the above-mentioned deficiencies of the prior art, the utility model provides a fitting alignment structure, which will not leave any alignment mark on the color segment code screen.

[0036] The color segment code screen 3 of the present invention adopts a large-piece bonding process. First, a large panel 100 with multiple segment code display patterns and a large color film 200 with multiple segment code color patterns are aligned and bonded through corresponding first alignment marks 130 and second alignment marks 230, and then the bonded large panel 100 and large color film 200 are cut, so that each group of corresponding screen areas 110 and color film areas 210 respectively forms a single color segment code screen 3. Since the first alignment marks 130 and the second alignment marks 230 are respectively located outside each of the screen areas 110 and each of the color film areas 210, the first alignment marks 130 and the second alignment marks 230 will not be left in the color segment code screen 3 formed after cutting, which can ensure the subsequent assembly efficiency of the whole machine.
