Abstract

The present technology relates to a display module and a manufacturing method, and a display apparatus that enable visual quality to be improved. A display module includes a display section and a film disposed on the display section to reduce light incident from outside and that is reflected from the display section. The display section includes an electronic board and a plurality of LED elements juxtaposed at predetermined intervals on a surface of the electronic board, the surface being on the film side. A distance from the LED element positioned closest to an end of the display section to the end of the display section is equal to or shorter than half the predetermined interval. The present technology is applicable to a LED tiling display.

Claims (58)

1 . A display module, comprising:

a display section;

a film on the display section, wherein

the film reduces reflection of light from the display section, and

the light is incident on the display module from an outside of the display module;

an electronic board in the display section; and

a plurality of Light Emitting Diode (LED) elements on a surface of the electronic board, wherein

a first LED element of the plurality of LED elements and a second LED element of the plurality of LED elements are juxtaposed at a specific interval on the surface of the electronic board,

the first LED element is adjacent to the second LED element,

the surface of the electronic board is on a side of the film,

a distance from a third LED element of the plurality of LED elements to an end of the display section is equal to or shorter than half of the specific interval, and

a position of the third LED element is closest to the end of the display section among positions of the plurality of LED elements.

2 . The display module according to claim 1 , further comprising a low-reflection layer on a surface of the film, wherein

the surface of the film is opposite to the display section, and

the low-reflection layer reduces the reflection of the light from the surface of the film.

3 . The display module according to claim 1 , wherein, in a case where the display module is viewed from a direction perpendicular to a front surface of the display section, a contour of the display section is substantially equal to a contour of the film.

4 . The display module according to claim 1 , wherein the film includes a circular polarizing film.

5 . The display module according to claim 4 , wherein the circular polarizing film includes at least one of a quarter wavelength film, a polarizing film, or a protective layer.

6 . The display module according to claim 5 , wherein the polarizing film has a thickness of 10 μm or less.

7 . The display module according to claim 5 , wherein the protective layer includes one of Cyclo Olefin Polymer (COP) or Poly Ethylene Terephthalate (PET).

8 . The display module according to claim 5 , further comprising a resin material on a side surface of the display module, wherein the resin material covers at least an end portion of the polarizing film on the side surface of the display module.

9 . The display module according to claim 8 , wherein the resin material includes a moisture-proof function.

10 . The display module according to claim 8 , wherein the resin material further covers at least a part of an end portion of the circular polarizing film and an end portion of the display section on the side surface of the display module.

11 . The display module according to claim 8 , wherein the resin material has a water vapor transmission rate of 100 g/m 2 ·24 h under an environment at a temperature of 40° C. and a humidity of 90% RH.

12 . The display module according to claim 8 , wherein the resin material is blackened.

13 . The display module according to claim 8 , wherein the resin material includes an edge emitting prevention function.

14 . The display module according to claim 1 , wherein the film includes a dimmer film.

15 . The display module according to claim 4 , wherein the circular polarizing film includes iodine.

16 . The display module according to claim 14 , wherein the dimmer film has a first transmission rate for a first wavelength component in a visible light region substantially same as a second transmission rate for a second wavelength component in the visible light region.

17 . The display module according to claim 1 , further comprising a planarization layer in the display section, wherein

the planarization layer is between the electronic board and the film,

the planarization layer includes a resin material, and

each of the plurality of LED elements is covered with the resin material of the planarization layer.

18 . A display apparatus, comprising:

a plurality of display modules juxtaposed in the display apparatus,

wherein each of the plurality of display modules includes:
