When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0019] Example 1 Combination Figure 1 and Figure 2 As shown, the display unit 1 of this utility model is schematically displayed, including the display component 10; like Figure 1 The display component 10 includes a plurality of light-emitting units 11 arranged in a ring. The plurality of light-emitting units 11 in the display component 10 are arranged in a ring. Each light-emitting unit 11 includes a plurality of LED beads 111 with different light-emitting colors. The light-emitting colors of the plurality of LED beads 111 in two adjacent light-emitting units 11 in the display component 10 are arranged symmetrically along an axis. The plurality of light-emitting units 11 arranged in a ring can reduce the color shift phenomenon of the display component 10 in a specific direction.

[0020] In this embodiment, the number of display components 10 is N. Along the direction away from the center of the ring, the Nth display component 10 is located outside the (N-1)th display component 10. The N display components 10 are arranged concentrically, which makes the multiple ring-shaped display components 10 nested to form a multi-ring display structure. The multi-ring display structure can improve the display brightness of the display unit 1. The light emission colors of the multiple LED beads 111 are arranged sequentially along the tangent of the ring. The multiple LED beads 111 in the light emission unit 11 are arranged in a straight line, and the color arrangement order of the multiple LED beads 111 in all light emission units 11 is consistent.

[0021] The light-emitting unit 11 includes multiple LED beads 111 with different light-emitting colors, and the light-emitting colors of the multiple LED beads 111 are arranged sequentially along the tangent of the ring. Any tangent line is made about the ring, and the direction of the tangent line is the tangent direction. The tangent line has a unique intersection point with the ring. When moving clockwise or counterclockwise along the ring, the instantaneous velocity when passing through the intersection point has a corresponding first direction, and the tangent direction is the same as the first direction. Specifically, the light-emitting unit 11 contains three LED beads 111, which emit blue, green, and red light respectively, and are named blue LED bead 111a, green LED bead 111b, and red LED bead 111c. The three LED beads 111 with different light-emitting colors can be combined to match their brightness ratios, so that the light-emitting unit 11 can display more different colors. The multiple LED beads 111 in the light-emitting unit 11 are arranged in a straight line, and the color arrangement order of the multiple LED beads 111 in all light-emitting units 11 is consistent. For example, the color arrangement order of the multiple LED beads 111 in all light-emitting units 11 is red, green, and blue. The straight line arrangement of the multiple LED beads 111 in each light-emitting unit 11 is tangential to the circular display component 10. Of course, the number of LED beads 111 in the light-emitting unit 11 can also be 4, 5, or other numbers. In addition to blue, green, and red, other colors such as white and yellow can also be used. When the display component 10 has 3 light-emitting units 11, the LED beads 111 in each light-emitting unit 11 are arranged in a straight line to form a triangle; when the display component 10 has 4 light-emitting units 11, the LED beads 111 in each light-emitting unit 11 are arranged in a straight line to form a square; when the display component 10 has 6 light-emitting units 11, the LED beads 111 in each light-emitting unit 11 are arranged in a straight line to form a hexagon.

[0022] Furthermore, the number of light-emitting units 11 in the Nth display component 10 is M times the number of light-emitting units 11 in the (N-1)th display component 10, where M is greater than or equal to 2 and M is an integer. For example, assuming M equals 2, the second display component 10 is located outside the first display component 10, that is, the outer diameter of the second display component 10 is larger than the outer diameter of the first display component 10. In this case, the second display component 10 has 8 light-emitting units 11, and the first display component 10 has 4 light-emitting units 11. Similarly, the third display component 10 is located outside the second display component 10, that is, the outer diameter of the third display component 10 is larger than the outer diameter of the second display component 10. In this case, the third display component 10 has 16 light-emitting units 11, and the second display component 10 has 8 light-emitting units 11.

[0023] like Figure 2To further improve the display brightness of the display unit 1, the light-emitting side of the LED beads 111 is provided with a first lens 30 for concentrating the emitted light, and each LED bead 111 corresponds to one first lens 30. The display unit 1 also includes a substrate 20 and a second lens 40. The light-emitting unit 11 is disposed on the substrate 20, which can support multiple light-emitting units 11 and form the aforementioned display assembly 10. The second lens 40 is disposed above the display assembly 10 and the substrate 20. The second lens 40, the LED beads 111 and the substrate 20 are stacked sequentially. All display assemblies 10 are located inside the projection outline of the second lens 40 on the substrate 20. The second lens 40 is used to concentrate the light emitted by multiple LED beads 111 in the light-emitting unit 11. The light emitted by the LED beads 111 passes through the first lens 30 and the second lens 40 in sequence and illuminates the outside. The light concentrated by the first lens 30 and the second lens 40 can concentrate the light emitted by the display unit 1 to the normal direction of the substrate 20, which can greatly improve the display brightness. The light-emitting unit 11 also includes a sub-board 112, on which multiple LED beads 111 are disposed. The sub-board 112 is disposed on the substrate 20. The circuit on the sub-board 112 is electrically connected to the circuit on the substrate 20, thereby realizing the electrical connection between the LED beads 111 and the substrate 20 for transmitting electrical energy and displaying control signals.

[0024] Example 2 like Figure 3 This embodiment discloses a display device 100, including a circuit board and a display unit 1 as described above. A plurality of display units 1 are disposed on the circuit board. The plurality of display units 1 may be arranged in a matrix on the circuit board or arranged along a straight line on the circuit board.

[0025] The multiple light-emitting units 11 in the display component 10 are arranged in a circular ring, so that the multiple circular display components 10 are nested with each other to form a multi-ring display structure. The multiple light-emitting units 11 arranged in a ring can reduce the color shift phenomenon of the display component 10 in a specific direction, and the multi-ring display structure can improve the display brightness of the display unit 1.

[0026] In summary, the display unit 1 includes a display component 10, which includes a plurality of light-emitting units 11 arranged in a ring. Each light-emitting unit 11 includes a plurality of LED beads 111 with different emitting colors. The emitting colors of the plurality of LED beads 111 in two adjacent light-emitting units 11 in the display component 10 are arranged symmetrically along an axis. The plurality of light-emitting units 11 arranged in a ring can reduce the color shift phenomenon of the display component 10 in a specific direction.
