Abstract

Provided is a display panel, including a first display area and a second display area. A transparent collimator is provided in a gap between two adjacent sub-pixels in the first display area, and meanwhile, a substrate under the collimator is a thinner substrate or a transparent substrate. Thus, a certain display area of the display panel possesses good light transmittance and resolution.

Claims (31)

1. A display panel, including a first display area and a second display area; wherein the display panel further includes:

a first sub-pixel located in the first display area; wherein a first pixel gap is formed between adjacent first sub-pixels;

a second sub-pixel located in the second display area; wherein a second pixel gap is formed between adjacent second sub-pixels; and

two or more collimators located in the first display area, wherein each of the collimators is disposed in one first pixel gap;

wherein in the first display area and the second display area, the display panel further includes:

a substrate;

a thin film transistor layer, disposed on one surface of the substrate, wherein the thin film transistor layer includes a plurality of thin film transistors, and each of the thin film transistors corresponds to one first sub-pixel or one second sub-pixel;

a pixel definition layer, disposed on the thin film transistor layer;

a light emitting layer, disposed in the pixel definition laver;

a via hole, disposed between two thin film transistors of the first displa area and extended from the light emitting layer to an interior of the thin film transistor layer:

a first inorganic layer, formed on the light emitting layer, on an inner sidewall of the via hole and on a bottom surface of the via hole; and

an organic layer, formed on the first inorganic layer, wherein in the first display area, the organic layer completely fills the via hole to form a corresponding collimator.

2. The display panel according to claim 1 , wherein a pixel area density of the first sub-pixels in the first display area is same as a pixel area density of the second sub-pixels in the second display area.

3. The display panel according to claim 1 , wherein the first pixel gap in the first display area is larger than the second pixel gap in the second display area.

4. The display panel according to claim 1 , wherein as the first sub-pixel and the second sub-pixel have a same color, and an area of the first sub-pixel is less than or equal to an area of the second sub-pixel.

5. The display panel according to claim 1 , wherein the two or more collimators are arranged in at least one straight line; or the two or more collimators are arranged in a matrix; or the two or more collimators are evenly distributed in the first display area.

6. The display panel according to claim 1 , wherein a plan view shape of the collimators is a diamond, a circle, a rectangle, a regular polygon or a curved polygon.

7. The display panel according to claim 1 , wherein in the first display area and the second display area:

each of the collimators is correspondingly disposed in one via hole.

8. The display panel according to claim 7 , wherein the display panel further includes a photosensitive sensor, disposed on one side of the substrate away from the collimator, wherein the photosensitive sensor possesses a photosensitive side, and the photosensitive side correspondingly faces the collimator;

wherein one side of the substrate possesses a groove toward the photosensitive sensor, and the groove corresponds to one photosensitive sensor.

9. The display panel according to claim 7 , wherein the display panel further includes:

a second inorganic layer, formed on the organic layer;

a touch layer, disposed on the second inorganic layer;

a polarizer, disposed on the touch layer; and

a cover, disposed on the polarizer.

10. The display panel according to claim 1 , wherein in the first display area and the second display area, the thin film transistor layer further includes:

a dielectric layer, disposed on the plurality of thin film transistors; and

a planarization layer, disposed on the dielectric layer;

wherein a refractive index of the organic layer is greater than a refractive index of the pixel definition layer;

a refractive index of the organic layer is greater than a refractive index of the planarization layer.
