Each tiled display element 20 has a display area 20a and a non-display area 20b located at the periphery of the display area 20 a. The display area 20a of the tiled display unit 20 is provided with a plurality of pixels, each pixel includes a first red sub-pixel emitting red light, a first green sub-pixel emitting green light, and a first blue sub-pixel emitting blue light, so that the display area 20a of the tiled display unit 20 can display. The non-display area 20b of the tiled display unit 20 is not displayed such that it is not displayed at the tiled location between any adjacent two of the tiled display units 20.
In the present embodiment, the tiled display unit 20 is a liquid crystal display panel. It is understood that the tiled display unit 20 can also be any one of a micro-led display panel, a sub-millimeter led display panel, and an inorganic led display panel.
In the present embodiment, the plurality of tiled display units 20 are identical. Each tiled display element 20 can be any one of square and rectangular in shape.
In this embodiment, the display substrate 30 is disposed at the splicing position corresponding to the two adjacent splicing display units 20, and the display substrate 30 is located at the light emitting side of the splicing display units 20, so that the display substrate 30 shields the non-display area 20b at the splicing position of the two adjacent splicing display units 20, thereby improving the problem of splicing black edges when the splicing display panel 10 displays.
Specifically, the display substrate 30 covers the non-display area 20b on one side of the adjacent two tiled display units 20 close to the tiled position, so that the display substrate 30 completely covers the non-display area 20b on one side of the adjacent two tiled display units 20 close to the tiled position, and the problem of tiled black edges occurring when the tiled display panel 10 displays is avoided.
In the present embodiment, the display substrate 30 is used for emitting a first light beam to perform display.

In other embodiments, if the tiled display unit 20 is composed of inorganic light emitting diodes and the display substrate 30 is a liquid crystal display panel or other display panel with a narrow viewing angle, the viewing angle of the display substrate 30 is smaller than that of the tiled display unit 20.
It should be noted that, when the display substrate 30 includes the inorganic light emitting diode chip 302 and the tiled display unit 20 is a liquid crystal display panel, because the light emitting principle of the inorganic light emitting diode chip 302 is different from that of the liquid crystal display panel, the luminance of the liquid crystal display panel decreases faster from the front viewing angle (the viewing angle in the direction perpendicular to the display surface) to the off-axis viewing angle (the viewing angle in the direction deviating from the front viewing angle) when displaying, and the luminance of the display substrate 30 formed by the inorganic light emitting diode chip 302 decreases slower from the front viewing angle (the viewing angle in the direction perpendicular to the display surface) to the off-axis viewing angle (the viewing angle in the direction deviating from the front viewing angle) when displaying, so that the viewing angle of the display substrate 30 formed by the inorganic light emitting diode chip 302 is larger than the viewing angle of the tiled display unit 20 formed by the liquid crystal display panel.

When the viewing angle of the display substrate 30 is larger than that of the tiled display unit 20, the divergence angle of the first light beam L1 is larger than that of the second light beam L2, so that the light emitted from the display substrate 30 passes through the light modulation structure 401 and then the divergence angle is narrowed, and the viewing angle of the display substrate 30 is reduced and matched with that of the tiled display unit 20.
As shown in fig. 2, the first light beam L1 emitted from the display substrate 30 enters obliquely with respect to the bottom surface of the light modulation structure 401, the first light beam L1 is refracted by the light modulation structure 401 and then exits the second light beam L2, the second light beam L2 exits perpendicularly to the bottom surface of the light modulation structure 401, and at this time, the divergence angle of the first light beam L1 is greater than that of the second light beam L2.
In the present embodiment, the light adjusting structure 401 includes a light converging lens to narrow the divergence angle of the first light beam L1. As shown in fig. 3, the light-collecting lens includes a triangular prism lens, the longitudinal section of the triangular prism lens is a triangle, and the triangle may be an isosceles right triangle or an equilateral triangle. In other embodiments, the light collecting lens may also include a semi-cylindrical lens.
