Abstract

A display apparatus includes a display panel including a first display portion including, the first display portion including a first area and a second area alternately arranged in one direction, a first emission device being disposed in the first area and the second area being located adjacent to the first area and configured to transmit external light, an electronic component facing one surface of the display panel and arranged corresponding to at least the second area, and a transmittance control component between the display panel and the electronic component and configured to control transmittance of the second area.

First claim

What is claimed is:

1. A display apparatus including: a display panel including a first display portion and a second display portion, the first display portion including a first emission device and a transmission area adjacent to the first emission device, and the second display portion including a second emission device and a non-emission area adjacent to the second emission device; an electronic component facing one surface of the display panel and arranged to correspond to at least the transmission area of the first display portion; and a transmittance control component between the display panel and the electronic component and configured to control transmittance of the transmission area of the first display portion, wherein the transmission area of the first display portion is configured to transmit external light and the non-emission area of the second display portion is configured not to transmit the external light, wherein each of the first emission device and the second emission device includes: a first electrode; a second electrode facing the first electrode; and an emission layer between the first electrode and the second electrode, wherein an insulating layer is disposed on the first electrodes of the first and second emission devices and covers edges of the first electrodes of the first and second emission devices, the insulating layer including a first opening corresponding to a part of the first electrode of the first emission device, a second opening corresponding to the transmission area of the first display portion and a third opening corresponding to a part of the first electrode of the second emission device, and the insulating layer disposed in the non-emission area in the second display portion.

2. The display apparatus of claim 1 , further including a driver configured to drive each of the first display portion and the second display portion independently from each other.

3. The display apparatus of claim 1 , wherein the external light includes ambient light and light emitted from the electronic component.

4. The display apparatus of claim 1 , further including a lens between the transmittance control component and the electronic component, wherein the electronic component includes an image sensor.

5. The display apparatus of claim 4 , further including a controller configured to convert an optical signal passing through the lens and incident on the image sensor into image data and perform color restoration on the image data.

6. The display apparatus of claim 1 , the display panel includes: a first substrate having a first surface on which the first display portion and the second display portion are provided; and
a second substrate sealing the first substrate, and wherein the electronic component faces a second surface opposite to the first surface of the first substrate.

7. The display apparatus of claim 6 , wherein the transmittance control component includes:
the first substrate;
a third substrate facing the second surface of the first substrate; and
a transmittance control layer between the first substrate and the third substrate.

8. The display apparatus of claim 6 , wherein the first substrate includes a first part, a second part, and a bending part between the first part and the second part,
a second surface of the first part and a second surface of the second part face each other,
the first display portion and the second display portion are provided on a first surface of the first part, and
the electronic component is provided on a second surface of the second part.

9. A method of manufacturing a display apparatus, the method including:
providing a display panel, the display panel including a first display portion and a second display portion, the first display portion including a first emission device and a transmission area emission device, and the second display portion including a second emission device and a non-emission area adjacent to the second emission device;
arranging an electronic component to face one surface of the display panel and to correspond to at least the transmission area of the first display portion; and
arranging a transmittance control component between the display panel and the electronic component, the transmittance control component being configured to control transmittance of the transmission area of the first display portion,
wherein the transmission area of the first display portion is configured to transmit external light and the non-emission area of the second display portion is configured not to transmit the external light,
wherein the providing of the display panel includes:
arranging first electrodes of the first emission device and the second emission device on a first substrate;
arranging an insulating film on the first electrodes of the first emission device and the second emission device, the insulating film including a first openings that each exposes a part of the first electrode of the first emission device, a second openings corresponding to the transmission area of the first display portion and a third opening corresponding to a part of the first electrode of the second emission device;
arranging emission layers in the first openings and the third opening;
arranging a second electrode on the emission layers in the first openings and the third opening and in the second openings;
removing the second electrode in the second openings; and
arranging a second substrate to correspond to the first substrate, and
wherein the insulating film is disposed in the non-emission area in the second display portion.

10. The method of claim 9 , further including, before the arranging of the second electrode in the second openings, arranging an adhesive layer in the second openings,
wherein the removing of the second electrode from the second openings includes removing the adhesive layer and the second electrode from the second openings.

11. The method of claim 9 , further including arranging a lens between the transmittance control component and the electronic component.

12. The method of claim 9 , wherein the first substrate includes a first part, a second part, and a bending part between the first part and the second part,
a second surface of the first part and a second surface of the second part face each other, and
the arranging of the electronic component includes arranging the electronic component on the second surface of the second part of the first substrate.

13. A display apparatus including:
a display panel including a first display portion and a second display portion, the first display portion including a first emission device and a transmission area adjacent to the first emission device, and the second display portion including a second emission device and a non-emission area adjacent to the second emission device; and
an electronic component facing one surface of the display panel and arranged to correspond to at least the transmission area of the first display portion, and
wherein the transmission area of the first display portion is configured to transmit external light and the non-emission area of the second display portion is configured not to transmit the external light,
wherein an electrode is not disposed in an area corresponding to the electronic component of the transmission area of the first display portion,
