Abstract

A display panel and a manufacturing method thereof are provided. The display panel includes a substrate, first sub-pixels and second sub-pixels. The first sub-pixels are disposed on the substrate. The first sub-pixels have a first orienting characteristic. A first adherent material is disposed between the first sub-pixels and the substrate. The second sub-pixels are disposed on the substrate. The second sub-pixels have a second orienting characteristic. A second adherent material is disposed between the second sub-pixels and the substrate. The first orienting characteristic and the second orienting characteristic are different. The first adherent material and the second adherent material are different.

Claims (40)

1 . A display panel comprising:

a substrate;

a plurality of first sub-pixels disposed on the substrate, wherein the plurality of first sub-pixels have a first orienting characteristic, and a first adherent material is disposed between the plurality of first sub-pixels and the substrate; and

a plurality of second sub-pixels disposed on the substrate, wherein the plurality of second sub-pixels have a second orienting characteristic, and a second adherent material is disposed between the plurality of second sub-pixels and the substrate,

wherein the first orienting characteristic is different from the second orienting characteristic, and the first adherent material is different from the second adherent material,

wherein the plurality of first sub-pixels and the plurality of second sub-pixels are disposed in a plurality of corresponding display pixel regions, respectively,

the first orienting characteristic comprises a first position offset and a first angle offset between each of the plurality of first sub-pixels and each of the plurality of corresponding display pixel regions, and the second orienting characteristic comprises a second position offset and a second angle offset between each of the plurality of second sub-pixels and each of the plurality of corresponding display pixel regions,

the first position offset and the second position offset are different, and the first angle offset and the first angle offset are different,

wherein the first adherent material is solder and the second adherent material includes a sticky material.

2 . The display panel of claim 1 , wherein the first adherent material or the second adherent material comprises metals, photoresists, resin, colloids, black light shielding layers, color filters, or quantum dots.

3 . The display panel of claim 1 , comprising the plurality of display pixel regions, each of the plurality of display pixel regions comprises a main pixel region and a spare pixel region, wherein one of plurality of sub-pixels is disposed in one of the main pixel region and the spare pixel region.

4 . The display panel of claim 1 , wherein there is a first height between the plurality of first sub-pixels and the substrate, there is a second height between the plurality of second sub-pixels and the substrate, and the first height and the second height are different.

5 . The display panel of claim 4 , wherein the second height is greater than the first height.

6 . A manufacturing method of a display panel, comprising:

providing a substrate;

disposing a plurality of first sub-pixels on the substrate, wherein the plurality of first sub-pixels have a first orienting characteristic, and a first adherent material is disposed between the plurality of first sub-pixels and the substrate; and

disposing a plurality of second sub-pixels on the substrate, wherein the plurality of second sub-pixels have a second orienting characteristic, and a second adherent material is disposed between the plurality of second sub-pixels and the substrate,

wherein the first orienting characteristic is different from the second orienting characteristic, and the first adherent material is different from the second adherent material,

wherein the plurality of first sub-pixels and the plurality of second sub-pixels are disposed in a plurality of corresponding display pixel regions, respectively,

the first orienting characteristic comprises a first position offset and a first angle offset between each of the plurality of first sub-pixels and each of the plurality of corresponding display pixel regions, and the second orienting characteristic comprises a second position offset and a second angle offset between each of the plurality of two sub-pixels and each of the plurality of corresponding display pixel regions,

the first position offset and the second position offset are different, and/or the first angle offset and the first angle offset are different,

wherein the first adherent material is solder and the second adherent material includes a sticky material.

7 . The manufacturing method of claim 6 , wherein the first adherent material or the second adherent material comprises metals, photoresists, resin, colloids, black light shielding layers, color filters, or quantum dots.

8 . The manufacturing method of claim 6 , further comprising providing the plurality of display pixel regions, wherein each of the plurality of display pixel regions comprises a main pixel region and a spare pixel region, and one of the plurality of sub-pixels is disposed on one of the main pixel region and the spare pixel region.

9 . The manufacturing method of claim 6 , comprising:

determining that there is a defective third sub-pixel from the plurality of first sub-pixels by inspecting the plurality of first sub-pixels after disposing the plurality of first sub-pixels;

removing the third sub-pixel; and

disposing the plurality of second sub-pixels in a plurality of marked display pixel regions from which the third sub-pixel is removed.

10 . The manufacturing method of claim 9 , wherein the step of disposing the plurality of second sub-pixels in the plurality of marked display pixel regions from which the third sub-pixel is disposed comprises:

disposing the plurality of second sub-pixels in the plurality of display marked pixel regions after coating the second adherent material in the plurality of marked display pixel regions.

11 . The manufacturing method of claim 6 , wherein there is a first height between the plurality of first sub-pixels and the substrate, there is a second height between the plurality of second sub-pixels and the substrate, the first height and the second height are different.

12 . The manufacturing method of claim 11 , wherein the second height is greater than the first height.

13 . A display panel comprising:

a substrate;

a plurality of first sub-pixels disposed on the substrate, wherein the plurality of first sub-pixels have a first orienting characteristic, and a first adherent material is disposed between the plurality of first sub-pixels and the substrate; and

a plurality of second sub-pixels disposed on the substrate, wherein the plurality of second sub-pixels have a second orienting characteristic, and a second adherent material is disposed between the plurality of second sub-pixels and the substrate,

wherein the first orienting characteristic is different from the second orienting characteristic, and the first adherent material is different from the second adherent material,

wherein the plurality of first sub-pixels and the plurality of second sub-pixels are disposed in a plurality of corresponding display pixel regions, respectively,

the first orienting characteristic comprises a first position offset and a first angle offset between each of the plurality of first sub-pixels and each of the plurality of corresponding display pixel regions, and the second orienting characteristic comprises a second position offset and a second angle offset between each of the plurality of second sub-pixels and each of the plurality of corresponding display pixel regions,

the first position offset and the second position offset are different, and the first angle offset and the first angle offset are different.
