Abstract

An electronic apparatus including a window including a bezel region including a semi-transmission region and a non-transmission region surrounding the semi-transmission region, and a transmission region adjacent to the bezel region, and a display panel disposed under the window. The window includes a base substrate, a light blocking pattern overlapping the non-transmission region, and an ink layer overlapping the semi-transmission region. The ink layer includes a first ink layer disposed under the base substrate, and a second ink layer disposed under the first ink layer, having a density lower than that of the first ink layer, and having a light transmittance of about 90% or more in a wavelength range of about 540 nm.

Claims (72)

1 . An electronic apparatus comprising:

a window including:

a bezel region comprising a semi-transmission region and a non-transmission region surrounding the semi-transmission region; and

a transmission region adjacent to the bezel region; and

a display panel disposed under the window, wherein

the window comprises:

a base substrate;

a light blocking pattern overlapping the non-transmission region; and

an ink layer overlapping the semi-transmission region, and

the ink layer comprises:

a first ink layer disposed under the base substrate; and

a second ink layer disposed under the first ink layer, having a density lower than that of the first ink layer, and having a light transmittance of about 90% or more in a wavelength range of about 540 nm.

2 . The electronic apparatus of claim 1 , wherein, with respect to a direction extending from a center of the semi-transmission region to the non-transmission region, a first width of the first ink layer in the direction and a second width of the second ink layer in the direction are same.

3 . The electronic apparatus of claim 2 , wherein:

the light blocking pattern includes an opening overlapping the semi-transmission region; and

a third width of the opening in the direction is smaller than the first width and the second width.

4 . The electronic apparatus of claim 1 , wherein:

the first ink layer comprises a first surface parallel to a plane defined by a first direction and a second direction intersecting the first direction and a first side surface extending from the first surface and parallel to a third direction intersecting the first direction and the second direction,

the second ink layer comprises a second surface parallel to the plane and facing the first surface and a second side surface extending from the second surface and parallel to the third direction, and

the first side surface and the second side surface are aligned with each other.

5 . The electronic apparatus of claim 1 , wherein:

the light blocking pattern includes an opening overlapping the semi-transmission region; and

the ink layer fills the opening.

6 . The electronic apparatus of claim 1 , wherein:

the first ink layer is in physical contact with a lower surface of the light blocking pattern; and

the second ink layer is disposed to be spaced apart from the light blocking pattern with the first ink layer interposed therebetween.

7 . The electronic apparatus of claim 1 , wherein the first ink layer and the second ink layer have an integral shape.

8 . The electronic apparatus of claim 1 , wherein the second ink layer comprises a thermosetting resin.

9 . The electronic apparatus of claim 1 , wherein the light transmittance of the first ink layer in a wavelength range of about 540 nm is about 10% or less.

10 . The electronic apparatus of claim 1 , wherein the first ink layer comprises:

a base resin; and

a dye dispersed in the base resin.

11 . The electronic apparatus of claim 1 , wherein the light blocking pattern comprises:

a first light blocking pattern disposed under the base substrate; and

a second light blocking pattern disposed under the first light blocking pattern.

12 . The electronic apparatus of claim 11 , wherein:

the first light blocking pattern includes a first opening overlapping at least the semi-transmission region,

a second opening different from the first opening is defined in the second light blocking pattern, and

the ink layer fills the first opening and the second opening.

13 . The electronic apparatus of claim 1 , further comprising:

an infrared detection sensor overlapping the semi-transmission region.

14 . The electronic apparatus of claim 1 , wherein the display panel comprises:

a base layer;

pixels disposed on the base layer and overlapping the transmission region; and

an encapsulation layer disposed on the pixels.

15 . An electronic apparatus comprising:

an electronic part to output or receive a signal;

a window including:

a first region overlapping the electronic part;

a second region surrounding at least a portion of the first region; and

a third region adjacent to the second region; and

a display part disposed under the window, wherein

the window comprises:

a base substrate;

a light blocking pattern including an opening overlapping at least a portion of the first region; and

an ink layer overlapping the first region and filling the opening, and the ink layer comprises:

a first ink layer disposed under the base substrate and having a first width with respect to a direction extending from a center of the opening to the second region; and

a second ink layer disposed under the first ink layer and having a second width equal to the first width with respect to the direction.

16 . A method for manufacturing an electronic apparatus, the method comprising:

preparing a base substrate including a bezel region comprising a semi-transmission region and a non-transmission region surrounding the semi-transmission region, and a transmission region adjacent to the bezel region;

forming a light blocking pattern comprising an opening overlapping at least a portion of the semi-transmission region;

providing an ink composition comprising resin particles and a first ink so as to fill the opening in order to form a printing pattern;

performing a first curing of the printing pattern at a first temperature to form a preliminary ink layer; and

performing a second curing of the preliminary ink layer at a second temperature higher than the first temperature.

17 . The method of claim 16 , wherein a density of the resin particles is lower than a density of the first ink.

18 . The method of claim 16 , wherein:

the first temperature is less than a melting point of the resin particles; and

the second temperature is greater than or equal to the melting point of the resin particles.

19 . The method of claim 16 , wherein, in the forming of the preliminary ink layer, the resin particles are phase-separated to an upper portion of the preliminary ink layer.

20 . The method of claim 16 , wherein:

the resin particles comprise a thermosetting resin; and

in the performing of the second curing, the resin particles are melted and thermally cured.
