Tiled display system and tiled display device

Abstract

A tiled display system is disclosed, which includes: a plurality of circuit boards; a plurality of display devices electrically connected to each other via the plurality of circuit boards; and a controller driving the plurality of display devices to enable each display device to display a sub-frame, wherein the plurality of display devices include: a first display device and a second display device disposed adjacent to the first display device; wherein one of the plurality of circuit boards is at least partially overlapped with the first display device and the second display device and is electrically connected with the first display device and the second display device; and wherein the one of the plurality of circuit boards crosses a boundary between the first display device and the second display device.

What is claimed is: 
     
         1 . A tiled display system, comprising:
 a plurality of circuit boards;   a plurality of display devices electrically connected to each other via the plurality of circuit boards; and   a controller driving the plurality of display devices to enable each display device to display a sub-frame,   wherein the plurality of display devices comprise a first display device and a second display device disposed adjacent to the first display device,   wherein one of the plurality of circuit boards is at least partially overlapped with the first display device and the second display device and is electrically connected with the first display device and the second display device; and   wherein the one of the plurality of circuit boards crosses a boundary between the first display device and the second display device.   
     
     
         2 . The tiled display system of  claim 1 , wherein the first display device and the second display device are arranged in juxtaposition. 
     
     
         3 . The tiled display system of  claim 1 , wherein each of the plurality of display devices comprises a driving substrate and a display panel disposed on the driving substrate. 
     
     
         4 . The tiled display system of  claim 3 , wherein the display panel comprises a pixel array, and the driving substrate drives the display panel and has a refresh rate. 
     
     
         5 . The tiled display system of  claim 4 , wherein the refresh rate is in a range from 60 Hz to 3840 Hz. 
     
     
         6 . The tiled display system of  claim 1 , wherein the plurality of display devices are electrically connected to each other in a cascading manner. 
     
     
         7 . The tiled display system of  claim 1 , wherein the first display device and the second display device start displaying different sub-frames in sequence. 
     
     
         8 . A tiled display device, comprising:
 a driving substrate;   a plurality of display panels disposed on the driving substrate; and   a controller electrically connected to the driving substrate via a circuit board, and the controller driving the plurality of display panels via the driving substrate to enable each display panel to display a sub-frame,   wherein, in a normal direction of the driving substrate, a part of the circuit board is overlapped with the driving substrate and another part of the circuit board is not overlapped with the driving substrate.   
     
     
         9 . The tiled display device of  claim 8 , wherein the plurality of display panels are arranged in juxtaposition. 
     
     
         10 . The tiled display device of  claim 8 , wherein each of the plurality of display panels comprises a pixel array. 
     
     
         11 . The tiled display device of  claim 8 , wherein the plurality of display panels comprise a first display panel and a second display panel disposed adjacent to the first display panel. 
     
     
         12 . The tiled display device of  claim 11 , wherein the first display panel and the second display panel start displaying different sub-frames in sequence.
