The present application is further described below with reference to the accompanying drawings and examples.
As shown in fig. 1, the present embodiment provides a Display device including a plurality of LCD (Liquid Crystal Display) Display panels 1 and a plurality of LED Display panels 2. The LCD display panel 1 may include a backlight module 11 and a display module 12, the display module 12 is located on the backlight module 11, and the backlight module 11 is used for providing a backlight source for the display module 12. The display module 12 may include an array substrate (not shown), a liquid crystal layer (not shown), a color filter substrate (not shown), a polarizer (not shown), and the like. Specifically, the array substrate is located on the backlight module 11, the liquid crystal layer is located on the array substrate, the color film substrate is located on the liquid crystal layer, and the polarizer is located on the color film substrate. LCD display panel 1 has that display area is big, stability is high and advantages such as low cost, but LCD display panel 1 can't realize full screen display, and LCD display panel 1 has frame (non-display area) promptly, if directly splices a plurality of LCD display panel 1 for jumbo size display screen, has great concatenation gap between LCD display panel 1, can't realize seamless concatenation.
The LED display panel 2 includes a substrate (not shown in the figure), a light emitting device 21, and a Color Filter (Color Filter) 22. The light emitting device 21 is located on a substrate, which may be a PCB circuit board or a glass substrate, etc. The color film layer 22 is located on the light emitting device 21, the light emitting device 21 may be a Micro LED or a Mini LED, and the color film layer 22 is used for color filtering of light emitted by the light emitting device. The color film layer 22 may include a plurality of color films, which may include a plurality of color films, such as a red color film R, a green color film G, and a blue color film B, where the red color film R is used to filter red light, the green color film G is used to filter green light, and the blue color film B is used to filter a blue color film.

Preferably, the light emitting device 21 may be a white light emitting device, i.e., the light emitting device 21 is for emitting white light. Because the spectrum of the white light is similar to the spectrum of the backlight source of the backlight module 11 in the LCD display panel 1, the optical characteristic of the white light in the LED display panel 2 after being filtered by the color film layer 22 is close to the optical characteristic of the backlight source in the LCD display panel 1, which is beneficial to the splicing between the LCD display panel 1 and the LED display panel 2. Moreover, the LED display panel 2 adopts a single color light emitting device, so that the electrical property curve, the lifetime attenuation and other characteristics are more stable, and the characteristics of the light emitting devices with different colors are different, so that the difficulty of optical debugging can be reduced by adopting a white light emitting device for the LED display panel 2.
Specifically, as shown in fig. 2 to fig. 5, the plurality of LCD display panels 1 are distributed in an array, that is, the plurality of LCD display panels 1 may be distributed in a plurality of rows and a column, or in a plurality of rows and a plurality of columns.
