The embodiment of the present application provides a tiled LCD display screen 100, and referring to fig. 1 to 4, the tiled LCD display screen 100 at least includes a first LCD display screen 10, a second LCD display screen 20, and a third LCD display screen 30, and the third LCD display screen 30 is located between the first LCD display screen 10 and the second LCD display screen 20.
The third LCD panel 30 is an LCD panel processed by the GIP technology (a technology for laying out the scan circuit in the pixel region, which is a pixel scan integrated circuit), because the display panel can realize an ultra-narrow frame by the GIP technology. In addition, the third LCD panel 30 is also a slim LCD panel processed by thinning process, and the slim LCD panel may adopt a process of attaching a TFT (thin film transistor) and a CF (color filter substrate) to the frame side frame glue, so that it is close to realizing a zero frame.
The third LCD panel 30 is a slim LCD panel because the large-sized LCD panel is not suitable for the GIP technology and the side frame glue TFT and CF process, and the Gate routing is too long and has high impedance, so the required pixel scan integrated circuit design is complicated, and the side frame glue technology has high yield and reliability when applied to a small display panel. In addition, the third LCD screen utilizes a slender strip type design, can be applied to mixing during production in panel factories, and realizes the highest production benefit of single glass. It should be noted that, those skilled in the art may specifically set the size of the third LCD panel 30 according to actual situations, and the size is not specifically limited herein.
In order to reduce the cost, the first LCD display screen 10 and the second LCD display screen 20 are large-sized LCD display screens, and the large-sized LCD display screens are standard-sized LCD display screens. The resolution of the finally spliced LCD display screen 100 is nonstandard, and the resolution can be processed by back-end signal processing, so as to finally form a complete display image, and the display mode includes image expansion and segmentation display, or direct black insertion at the display edge.
A first concave portion 101 is disposed on a side of the first LCD panel 10 close to the third LCD panel 30, and the first concave portion 101 is located in the black matrix area 11 of the first LCD panel 10.
The black matrix area 11 of the first LCD panel 10 is a bm (black matrix) area of the first LCD panel 10.
A second concave portion 201 is disposed on a side of the second LCD panel 20 close to the third LCD panel 30, and the second concave portion 201 is located in the black matrix area 12 of the second LCD panel 20.
The black matrix area 12 of the second LCD panel 20 is a bm (black matrix) area of the second LCD panel 20.
One end of the third LCD panel 30 is disposed in the first recess 101, and the other end of the third LCD panel 30 is disposed in the second recess 201. The first concave part 101 and the second concave part 201 are respectively arranged in the black matrix area of the first LCD display screen 10 and the second LCD display screen 20, and then the third elongated LCD display screen 30 which is processed by the pixel scanning integrated circuit and is thinned is arranged in the first concave part 101 and the second concave part 201, so that the problem of splicing seams generated by splicing modules in a narrow frame splicing mode can be solved.
In some embodiments, a gap is formed between the first LCD display 10 and the second LCD display 20, and the side of the first LCD display 10 and the second LCD display 20 forming the gap is provided with a light shielding glue (in order to make the light shielding glue more clearly visible in the view, the light shielding glue disposed on the side of the first LCD display 10 is represented by a first light shielding glue 40, and the light shielding glue disposed on the side of the second LCD display 20 is represented by a second light shielding glue 50).
Because there is the clearance between first LCD display screen 10 and the second LCD display screen 20, consequently form the side in this clearance on first LCD display screen 10 and the second LCD display screen 20 and set up shading glue to carry out the shading, prevent the display screen light leak.
In some embodiments, the first LCD panel 10, the second LCD panel 20 and the third LCD panel 30 share a backlight module 60, the lower polarizer 102 of the first LCD panel 10 is disposed on the backlight module 60, and the lower polarizer 202 of the second LCD panel 20 is disposed on the backlight module 60.
Since a gap is left between the first LCD panel 10 and the second LCD panel 20, the light generated by the backlight module 60 can enter the third LCD panel 30 through the gap.
In some embodiments, the bottom of the first recess 101 is located on the color filter substrate of the first LCD display 10, and the bottom of the second recess 201 is located on the color filter substrate of the second LCD display 20 (to distinguish the color filter substrate of the first LCD display 10 from the color filter substrate of the second LCD display 20, the color filter substrate of the first LCD display 10 is represented by the first color filter substrate 103, and the color filter substrate of the second LCD display 20 is represented by the second color filter substrate 203).
That is, the depth of the first recess 101 is smaller than the thickness of the first color filter substrate 103, and the depth of the second recess 201 is smaller than the thickness of the second color filter substrate 203.
In some embodiments, the third LCD display 30 includes a diffuser 301 positioned over the first and second recesses 101 and 201.
The third LCD panel 30 further includes a diffusion sheet 301, and the diffusion sheet 301 is disposed on the first recess 101 and the second recess 201 to solve the problem that the backlight in the BM region cannot penetrate through.
In some embodiments, the first LCD display 10, the second LCD display 20, and the third LCD display 30 share one upper polarizer 70, and the upper polarizer 70 is disposed on the color filter substrate 302 of the third LCD display 30 (in order to distinguish the color filter substrate of the third LCD display 30 from the color filter substrate of the first LCD display 10 and the color filter substrate of the second LCD display 20, the color filter substrate of the third LCD display 30 is represented by the third color filter substrate 302).
Under the structure of the tiled LCD display 100, a distance between the third color film substrate 302 of the third LCD display 30 and the backlight module 60 is greater than a distance between the first color film substrate 103 of the first LCD display 10 and the backlight module 60, and a distance between the color film substrate 302 of the third LCD display 30 and the backlight module 60 is greater than a distance between the first color film substrate 103 of the second LCD display 20 and the backlight module 60, so that, when the first LCD display 10, the second LCD display 20 and the third LCD display 30 share one upper polarizer 70, the upper polarizer 70 has a certain distance from the first color film substrate 103, and the upper polarizer 70 has a certain distance from the second color film substrate 203, so that the upper polarizer 70 can only be disposed on the third color film substrate 302 of the third LCD display 30.
In some embodiments, a first planarization layer 80 is disposed between the upper polarizer 70 and the color filter substrate of the first LCD display 10, and a second planarization layer 90 is disposed between the upper polarizer 70 and the color filter substrate of the second LCD display 20. .
In the case that the first LCD display 10, the second LCD display 20, and the third LCD display 30 share one upper polarizer 70, the upper polarizer 70 has a certain distance from the first color film substrate 103, and the upper polarizer 70 has a certain distance from the second color film substrate 203, so that the first planarization layer 80 is disposed between the upper polarizer 70 and the first color film substrate 103, and the second planarization layer 90 is disposed between the upper polarizer 70 and the second color film substrate 203, so that the upper polarizer 70 does not incline to the first color film substrate 103 and the second color film substrate 203.
In some embodiments, the upper surface of the first planarization layer 80 is on the same plane as the lower surface of the color filter substrate of the third LCD display 30, and the upper surface of the second planarization layer 90 is on the same plane as the lower surface of the color filter substrate of the third LCD display 30.
The reason why the upper surface of the first planarization layer 80 and the lower surface of the color filter substrate of the third LCD display 30 are defined to be on the same plane, and the upper surface of the second planarization layer 90 and the lower surface of the color filter substrate of the third LCD display 30 are defined to be on the same plane is to make the upper polarizer 70 flat as a plane, not a curved surface.
That is, the thickness of the first flat layer 80 may be equal to or different from the thickness of the second flat layer 90, and when the distance between the upper polarizer 70 and the first color filter substrate 103 is equal to the distance between the upper polarizer 70 and the second color filter substrate 203, in order to make the upper polarizer 70 flat, the thickness of the first flat layer 80 is set to be equal to the thickness of the second flat layer 90. When the distance between the upper polarizer 70 and the first color filter substrate 103 is not equal to the distance between the upper polarizer 70 and the second color filter substrate 203, the thickness of the first planarization layer 80 is not equal to the thickness of the second planarization layer 90 in order to planarize the upper polarizer 70. As long as the upper surface of the first planarization layer 80 and the lower surface of the color filter substrate of the third LCD display 30 are on the same plane, and the upper surface of the second planarization layer 90 and the lower surface of the color filter substrate of the third LCD display 30 are on the same plane, so that the upper polarizer 70 is planarized to be a plane, rather than a curved surface, those skilled in the art can set the upper polarizer according to actual conditions, and no specific limitation is imposed herein.
In some embodiments, the first LCD display 10 includes a first upper polarizer 104, the second LCD display includes a second upper polarizer 204, the third LCD display includes a third upper polarizer 303, the first upper polarizer 104 is disposed on the color film substrate of the first LCD display 10, the second upper polarizer 204 is disposed on the color film substrate of the second LCD display 20, and the third upper polarizer 303 is disposed on the color film substrate of the third LCD display 30.
Namely, the first LCD panel 10, the second LCD panel 20 and the third LCD panel 30 each use a separate upper polarizer.
In some embodiments, the third LCD display 30 is fixedly connected to the first recess 101 and the second recess 201 by glue.
It should be noted that the third LCD panel 30 is not necessarily fixedly connected to the first recess 101 and the second recess 201 only by glue, and those skilled in the art can specifically set the third LCD panel according to actual situations, and the third LCD panel is not limited herein.
