All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. Furthermore, it should be understood that the detailed description and specific examples, while indicating exemplary embodiments of the invention, are given by way of illustration and explanation only, and are not intended to limit the scope of the invention. In the present application, unless indicated to the contrary, the use of the directional terms "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, and more particularly to the orientation of the figures of the drawings; while "inner" and "outer" are with respect to the outline of the device.
The embodiment of the application provides an LED display panel and a splicing display device. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.

As shown in fig. 2, the color gamut of the LED display panel 1 is significantly higher than the color gamut of the liquid crystal display panel 2, and therefore, a display difference exists at a joint between the liquid crystal display panel 2 and the LED display panel 1, specifically, a color difference and a brightness difference exist at the joint between the liquid crystal display panel 2 and the LED display panel 1, so that the LED display panel 1 has a color edge at the joint. As shown in fig. 3, the color edge of the LED display panel 1 is not easily visible to the general population. For the myopia people, when the light emitted by the LED display panel 1 enters the eyes of the user through the optical axis of the myopia lens 3, the user can not see the color edge; when light emitted from the LED display panel 1 enters the eyes of the user through the upper or lower portion of the myopic lens 3, the user sees a colored edge. In the embodiment of the present application, the colors of the LED chips at the edge of the LED display panel 1 in the column direction are red and blue, and therefore, the color edges are specifically red and blue edges. Of course, when the color of the LED chip at the edge of the LED display panel 1 in the column direction is green, the color edge seen by the myopic person may also be green.
In order to avoid the above problem, as shown in fig. 4 and fig. 6, the present embodiment provides an LED display panel 100 for being tiled with a liquid crystal display panel 200, wherein a tiled boundary 300 is provided between the LED display panel 100 and the liquid crystal display panel 200. The LED display panel 100 includes a substrate 110, a plurality of first pixel units 120 are disposed on the substrate 110, the first pixel units 120 include a plurality of light emitting devices 130, the plurality of light emitting devices 130 include a red light emitting device 131, a green light emitting device 132, a blue light emitting device 133, and a compensation light emitting device 134, the compensation light emitting device 134 is used to adjust a color gamut, and light emitting colors of any two light emitting devices 130 of the red light emitting device 131, the green light emitting device 132, the blue light emitting device 133, and the compensation light emitting device 134 are different; wherein, along the extending direction of the edge of the substrate 110 close to the splicing boundary 300, the light emitting colors of two adjacent light emitting devices 130 are different.

Specifically, the plurality of light emitting devices 130 are distributed in an array, and specifically, the plurality of light emitting devices 130 are arranged in an array of a plurality of rows and columns. Here, the light emitting colors of two adjacent light emitting devices 130 in the row direction X are different, and the light emitting colors of two adjacent light emitting devices 130 in the column direction Y are different. Under the structure, the LED display panel 100 can uniformly emit light, and in the extending direction of any one edge of the LED display panel 100, the light emitting colors of two adjacent light emitting devices 130 are different, so that the occurrence of a color edge can be effectively avoided.

Under this structure, the arrangement of the light emitting devices 130 in the first pixel unit 120 is sequentially arranged according to the distribution of the wavelength range, which is beneficial to lowering the color gamut of the LED display panel 100, and is also convenient to adjust the light emitting colors of the red light emitting device 131, the green light emitting device 132, and the blue light emitting device 133.
