Abstract

An electronic apparatus includes: an electronic module; a display panel disposed on the electronic module and including a first display region and a second display region adjacent to the first display region, the second display region overlapping the electronic module; and a polarization plate disposed on the display panel and including a first polarization region overlapping the first display region and a second polarization region including a polarization part and a non-polarization part having higher light transmittance than the polarization part, the non-polarization part overlapping the second display region.

First claim

What is claimed is:

1. An electronic apparatus comprising:
an electronic module;
a display panel disposed on the electronic module and comprising a first display region and a single second display region adjacent to the first display region, the single second display region overlapping the electronic module; and
a polarization plate disposed on the display panel and comprising a first polarization region overlapping the first display region and a second polarization region comprising polarization parts and non-polarization parts,
each of the non-polarization parts having higher light transmittance than each of the polarization parts, and
the polarization parts and the non-polarization parts being interleaved with one another and overlapping the single second display region.

2. The electronic apparatus of claim 1 , wherein:
the polarization plate comprises a polarizer layer as an uppermost layer, and
the polarizer layer comprises a polymer film and a light absorber dispersed in the polymer film.

3. The electronic apparatus of claim 2 , wherein a number of the light absorber per unit area in each of the non-polarization parts is smaller than a number of the light absorber per unit area in the first polarization region and each of the polarization parts.

4. The electronic apparatus of claim 2 , wherein the non-polarization parts are formed by removing the light absorber from the polymer film.

5. The electronic apparatus of claim 1 , wherein the display panel comprises:
a base layer;
a circuit layer disposed on the base layer and comprising at least one metal pattern; and
a light-emitting element layer disposed on the circuit layer and comprising a first electrode and a second electrode facing each other, and an emission layer disposed between the first electrode and the second electrode,
wherein the single second display region comprises a non-pixel region that does not comprise the at least one metal pattern and the first electrode, and a pixel region that comprises the at least one metal pattern and the first electrode.

6. The electronic apparatus of claim 5 , wherein:
the non-pixel region overlaps the non polarization parts, and
the pixel region overlaps the polarization parts.

7. The electronic apparatus of claim 5 , wherein:
each of the polarization parts overlaps at least one among the at least one metal pattern and the first electrode; and
each of the non-polarization parts does not overlap both the at least one metal pattern and the first electrode.

8. The electronic apparatus of claim 5 , wherein the at least one metal pattern comprises at least one among a lower shield pattern, a transistor, and a connection electrode.

9. The electronic apparatus of claim 8 , wherein each of the non-polarization parts does not overlap the at least one metal pattern.

10. The electronic apparatus of claim 1 , wherein:
each of the first display region and the single second display region comprises a plurality of pixel units; and
a number of the pixel units per unit area in the single second display region is smaller than a number of the pixel units per unit area in the first display region.

11. The electronic apparatus of claim 10 , wherein each of the plurality of pixel units comprises a first color light-emitting region, a second color light-emitting region, and a third color light emitting region.

12. The electronic apparatus of claim 1 , wherein:
the first display region comprises a first pixel unit comprising a plurality of light-emitting regions arranged spaced apart from each other when viewed in a plane; and
the single second display region comprises a second pixel unit comprising a plurality of light-emitting regions arranged different from an arrangement of the plurality of light-emitting regions in the first pixel unit.

13. The electronic apparatus of claim 1 , wherein the single second display region has a lower pixel density or a lower wiring density than the first display region.

14. An electronic apparatus comprising:
an electronic module;
a display panel disposed on the electronic module and comprising a first display region and a second display region adjacent to the first display region, the second display region overlapping the electronic module;
a polarization plate disposed on the display panel and comprising a first polarization region overlapping the first display region and a second polarization region comprising a polarization part and a non-polarization part having higher light transmittance than the polarization part, the non-polarization part overlapping the second display region; and
a support member disposed under the display panel,
wherein the support member defines a through-hole extending from a lowermost surface of the support member and terminating at a lowermost surface of the display panel and a portion of the electronic module is inserted into the through-hole.

15. The electronic apparatus of claim 14 , wherein:
the portion of the electronic module that is inserted into the through-hole is sized to fit in the through-hole, and
the electronic module comprises an additional portion which is not sized to fit in the through-hole.

16. A system for manufacturing an electronic apparatus, the electronic apparatus comprising:
an electronic module;
a display panel disposed on the electronic module and comprising a first display region and a second display region adjacent to the first display region, the second display region overlapping the electronic module; and
a polarization plate disposed on the display panel and comprising a first polarization region overlapping the first display region and a second polarization region comprising a polarization part and a non-polarization part having higher light transmittance than the polarization part, the non-polarization part overlapping the second display region,
wherein the system comprises:
a laser light source disposed under the display panel and configured to irradiate the second display region with laser light; and
cleaning liquid provided onto the second polarization region from above the polarization plate.

17. The system of claim 16 , wherein the second polarization region comprises polarization parts and non-polarization parts,
each of the non-polarization parts having higher light transmittance than each of the polarization parts, and
the polarization parts and the non-polarization parts being interleaved with one another and overlapping the second display region.

18. The system of claim 16 , wherein the electronic apparatus further comprises a support member disposed under the display panel,
wherein the support member defines a through-hole extending from a lowermost surface of the support member and terminating at a lowermost surface of the display panel and a portion of the electronic module is inserted into the through-hole.
