[0034] Example 1

[0035] See also Figures 1 to 6, is a navigation symbol segment code screen provided by the utility model, which includes a lower polarizer 1, a lower glass 2, an upper glass 3 and an upper polarizer 4 which are sequentially stacked from bottom to top, and a segment code pattern is arranged on the lower glass 2, and the segment code pattern includes a circular ring pattern set 31, an arrow pattern set 32 ​​and an auxiliary pattern set 33, the arrow pattern set 32 ​​is arranged outside the circular ring pattern set 31, and the auxiliary pattern set 33 includes a first auxiliary pattern set 331 and a second auxiliary pattern set 332, the first auxiliary pattern set 331 is arranged inside the circular ring pattern set 31, and the second auxiliary pattern set 332 is arranged below the circular ring pattern set 31. The circular ring pattern set 31, the arrow pattern set 32 ​​and the auxiliary pattern set 33 are all provided with a plurality of basic patterns 300 that can be lit up separately, and one or more basic patterns 300 of the circular ring pattern set 31, the arrow pattern set 32 ​​and the auxiliary pattern set 33 can form a navigation arrow symbol when they are all lit up. By lighting up one or more basic patterns 300 of the circular pattern set 31, the arrow pattern set 32 ​​and the auxiliary pattern set 33 at the same time, these lit basic patterns 300 form a navigation arrow symbol, thereby realizing the display of the navigation pattern. Compared with the traditional full-display LCD screen, the cost can be greatly reduced, which is suitable for navigation displays that are more sensitive to cost, thereby improving the competitiveness of the product.

[0036] Further, the arrow pattern set 32 ​​includes nine basic patterns 300, including an up arrow, a left down arrow, a right down arrow, a left arrow, a right arrow, an upper left arrow, a lower left arrow, an upper right arrow and a lower right arrow. Only one arrow needs to be lit each time, and no other arrows need to be lit.

[0037] Furthermore, the second auxiliary pattern set 332 is provided with two basic patterns 300, which are respectively provided above the left downward arrow and the right downward arrow, and the two basic patterns 300 are used for displaying the U-turn pattern.

[0038] Furthermore, the circular ring pattern set 31 includes twenty basic patterns 300, and the twenty basic patterns 300 are arranged in sequence to form a circular ring, and most of the circular ring patterns are used for displaying island patterns.
