Abstract

Official abstract text for this publication.

An organic light-emitting diode (OLED) display is disclosed. In one aspect, the OLED display includes a substrate including a display area configured to display an image and a transmission area positioned on a periphery of the display area, a first insulating layer positioned in the display area and the transmission area and a thin film transistor positioned in the display area and formed on the first insulating layer. The OLED display also includes a second insulating layer positioned in the display area and the transmission area and covering the thin film transistor and an organic light-emitting element positioned in the display area and formed on the second insulating layer. The second insulating layer has a first transmission hole exposing a portion of the first insulating layer on the transmission area, and a spacer is positioned on the first insulating layer in the transmission hole.

First claim

Opening claim text (preview).

What is claimed is: 1 . An organic light emitting diode (OLED) display comprising: a substrate including a display area configured to display an image and a transmission area positioned on a periphery of the display area; a first insulating layer positioned in the display area and the transmission area and formed on the substrate; a thin film transistor positioned in the display area and formed on the first insulating layer; a second insulating layer positioned in the display area and the transmission area and formed on the first insulating layer to cover the thin film transistor; and an organic light-emitting element positioned in the display area and formed on the second insulating layer to be connected to the thin film transistor, wherein the second insulating layer has a first transmission hole exposing a portion of the first insulating layer on the transmission area, and wherein a spacer is positioned on the first insulating layer in the transmission hole. 2 . The OLED display of claim 1 , wherein the thin film transistor includes: a semiconductor layer covered by the first insulating layer; a gate electrode formed on the first insulating layer; and a source electrode and a drain electrode positioned on the gate electrode and connected to the semiconductor layer. 3 . The OLED display of claim 2 , wherein the first insulating layer includes: a buffer layer formed on the substrate; and a gate insulating layer formed on the buffer layer and covering the semiconductor layer. 4 . The OLED display of claim 3 , wherein at least one of the buffer layer and the gate insulating layer includes a siloxane-based resin. 5 . The OLED display of claim 3 , wherein the gate insulating layer comprises a plurality of layers. 6 . The OLED display of claim 2 , wherein the organic light-emitting element includes: a first electrode formed on the second insulating layer and connected to the drain electrode; an organic emission layer positioned on the first electrode; and a second electrode positioned on the organic emission layer, and wherein a pixel definition layer defining the pixel area exposing a portion of the first electrode is formed on the second insulating layer, and wherein the organic emission layer contacts the first electrode in the pixel area. 7 . The OLED display of claim 6 , wherein the second electrode is positioned only in the display area. 8 . The OLED display of claim 6 , wherein the pixel definition layer has a second transmission hole exposing a portion of the first insulating layer in the transmission area and is positioned to correspond to the first transmission hole. 9 . The OLED display of claim 6 , wherein the spacer protrudes onto the pixel definition layer. 10 . The OLED display of claim 6 , wherein: the height of the spacer protruding onto the pixel definition layer is about 1 μm-about 3 μm. 11 . The OLED display of claim 6 , wherein the spacer includes, a first protrusion formed on the first insulating layer; and a second protrusion formed on the first protrusion. 12 . The OLED display of claim 11 , wherein the first protrusion is integrally formed with the second insulating layer. 13 . The OLED display of claim 12 , wherein the second protrusion is integrally formed with the pixel definition layer. 14 . The OLED display of claim 6 , further comprising an interlayer insulating layer formed on the first insulating layer covering the gate electrode, wherein the interlayer insulating layer has a third transmission hole exposing a portion of the first insulating layer in the transmission area and positioned to correspond to the first transmission hole. 15 . The OLED display of claim 6 , further comprising an interlayer insulating layer formed on the first insulating layer and covering the gate electrode, wherein a portion of the interlayer insulating layer is exposed through the first transmission hole in the transmission area. 16 . The OLED display of claim 1 , wherein the spacer comprises a plurality of spacers in the transmission hole. 17 . An organic light-emitting diode (OLED) display comprising: a substrate including a display area configured to display an image and a transmission area positioned on a periphery of the display area; a first insulating layer positioned in the display area and the transmission area; a second insulating layer positioned in the display area and the transmission area and formed on the first insulating layer, wherein the second insulating layer has a first transmission hole exposing a portion of the first insulating layer on the transmission area; and a spacer positioned on the first insulating layer in the transmission hole. 18 . The OLED display of claim 17 , wherein the spacer includes: a first protrusion formed on the first insulating layer; and a second protrusion formed on the first protrusion. 19 . The OLED display of claim 18 , wherein the first protrusion is greater in size than the second protrusion. 20 . The OLED display of claim 18 , wherein the height of the first protrusion is greater than that of the second protrusion.
