Abstract

A display apparatus includes a display panel having a plurality of sub-pixels, a front member disposed over an upper surface of the display panel, and a first plate disposed under a rear surface of the display panel, the display panel and the first plate including a same plane in a vertical direction of the display panel.

Claims (48)

1 . A display apparatus, comprising:

a display panel having a substrate, the substrate including a plurality of sub-pixels, the display panel including a thin film transistor and a light emitting device disposed in each sub-pixel of the substrate;

a cover window disposed on an upper surface of the display panel; and

a first plate disposed on a rear surface of the display panel,

wherein the display panel has an end face corresponding to an outermost boundary of the display panel and the first plate has an end face corresponding to an outermost boundary of the first plate, and the end face of the display panel and the end face of the first plate are arranged along a same plane in a vertical direction of the display panel,

wherein the first plate includes a step in an outermost edge of the first plate recessed toward a center of the first plate from the end face of the first plate, and

wherein the first plate is metal.

2 . The display apparatus of claim 1 , wherein the first plate has a first thickness and a second thickness that is different from the first thickness.

3 . The display apparatus of claim 2 , wherein the first thickness is less than the second thickness, and the first thickness is at the edge of the first plate.

4 . The display apparatus of claim 1 , wherein the step of the first plate has a right angle shape.

5 . The display apparatus of claim 1 , wherein the step of the first plate has a curved shape.

6 . The display apparatus of claim 1 , wherein the step of the first plate has a step down shape with a right angle between steps of the step down shape.

7 . The display apparatus of claim 1 , wherein the metal of the first plate includes at least one of: copper, copper foam, stainless steel, an alloy material thereof, and junction structures thereof.

8 . The display apparatus of claim 1 , further comprising:

an adhesive layer disposed between the display panel and the cover window;

a polarizing plate disposed between the adhesive layer and the display panel; and

a second plate disposed between the display panel and the first plate, wherein the second plate is a thin film comprising at least one of: polyimide (PI), polyethylene terephthalate (PET), and polyethylene naphthalate (PEN), and

wherein the adhesive layer, the polarizing plate, and the second plate are arranged along the same plane as the display panel and the first plate.

9 . The display panel of claim 1 , wherein the end face of the display panel and the end face of the first plate are recessed with respect to an end face of the cover window.

10 . The display apparatus of claim 1 , wherein the step corresponds to a portion of the first plate with a reduced thickness at the same plane.

11 . The display apparatus of claim 1 , wherein the step of the first plate is one of at least two steps at the outermost edge of the first plate.

12 . The display apparatus of claim 1 , wherein the outermost edge of the first plate overlaps an outermost edge of the display panel.

13 . A display apparatus comprising:

a multi-layer stack, including:

a display panel including a substrate, the substrate including a display area having a plurality of sub-pixels, wherein the display area includes a camera area having a first hole, the display panel including a thin film transistor and a light emitting device disposed in each sub-pixel;

a first plate disposed under a rear surface of the display panel, the first plate including a second hole and a step around the second hole, the second hole overlapping the first hole;

a cover window disposed on a front surface of the display panel;

an adhesive layer between the display panel and the cover window;

a polarizing plate between the adhesive layer and the display panel;

a second plate under the display panel; and

a light blocking member on inner side surfaces of the first hole and the second hole,

wherein the light blocking member has a further step corresponding to the step at an edge of the first plate,

wherein the multi-layer stack includes the cover window, the adhesive layer, the polarizing plate, the display panel, the second plate, and the first plate in successive order from a top to a bottom of the multi-layer stack.

14 . The display apparatus of claim 13 , wherein the second hole includes a first portion and a second portion, a diameter of the first portion of the second hole being equal to a diameter of the first hole, and a diameter of the second portion of the second hole being greater than the diameter of the first hole,

wherein the first plate is a metal plate and the second plate is a thin film comprising at least one of: polyimide (PI), polyethylene terephthalate (PET), and polyethylene naphthalate (PEN).

15 . The display apparatus of claim 13 , wherein the step of the first plate has a right angle shape.

16 . The display apparatus of claim 13 , wherein the step of the first plate has a curved shape.

17 . The display apparatus of claim 13 , wherein the step of the first plate has a stair shape with a right angle.

18 . The display apparatus of claim 13 , wherein the first plate includes at least two different thicknesses.

19 . The display apparatus of claim 13 , wherein the display panel and the first plate include a same plane in a vertical direction of the display panel.

20 . The display apparatus of claim 19 , wherein the display panel and the first plate include side surfaces arranged along the same plane.

21 . The display apparatus of claim 20 , wherein the step in the first plate is along the same plane.

22 . The display apparatus of claim 21 , wherein a thickness of the edge of the first plate is less than a thickness of a remaining area of the first plate.

23 . The display apparatus of claim 22 , wherein the display panel further includes a non-display area surrounding the display area, and

wherein the edge of the first plate overlaps the non-display area, and the remaining area of the first plate overlaps the display area and a part of the non-display area.

24 . The display apparatus of claim 13 , wherein the step of the first plate is a round shape.

25 . The display apparatus of claim 13 , wherein the edge of the first plate overlaps an edge of the display panel.

26 . The display apparatus of claim 1 , wherein the step is directed towards an inside of the display panel so that a thickness of the first plate and the display panel at the step is less than a thickness of the first plate and the display panel in a remaining region of the first plate and the display panel.
