Display apparatus
View Patent ↗A display apparatus capable of preventing electromagnetic noise. The display apparatus includes a substrate, a sealing member facing the substrate, a display unit arranged between the substrate and the sealing member, a driving chip arranged on the substrate to transmit an electrical signal to the display unit, a conductive cover layer covering the driving chip and a flexible circuit substrate including a conductive cover layer and signal line, the signal line being electrically connected to the driving chip.
1. A display apparatus, comprising:
a substrate;
a sealing member facing the substrate;
a display unit arranged between the substrate and the sealing member;
a driving chip arranged on the substrate to transmit an electrical signal to the display unit; and
a flexible circuit substrate including a conductive cover layer and a signal line, the signal line being electrically connected to the driving chip, the conductive cover layer covering the driving chip.
2. The display apparatus of claim 1 , wherein the signal line and the conductive cover layer are electrically insulated from each other by an insulating layer.
3. The display apparatus of claim 1 , wherein the conductive cover layer comprises a metal.
4. The display apparatus of claim 1 , wherein the conductive cover layer is spaced-apart from the driving chip.
5. The display apparatus of claim 1 , wherein the substrate comprises an extended portion that is absent of the sealing member, the driving chip being arranged within the extended portion of the substrate.
6. The display apparatus of claim 1 , further comprising a protection layer comprising an insulating material arranged on the conductive cover layer.
7. The display apparatus of claim 1 , the conductive cover layer to prevent electromagnetic waves produced in a vicinity of the driving chip from reaching the display unit.
8. The display apparatus of claim 1 , the display unit comprising a plurality of pixels, each pixel comprising:
a thin film transistor; and
an organic light-emitting device electrically connected to the thin film transistor, the organic light-emitting device including an organic light-emitting layer.
9. A display apparatus, comprising:
a substrate having a display portion and an extended portion external to the display portion;
a sealing member arranged on the substrate in the display portion only;
a display unit arranged between the substrate and the sealing member;
a driving chip arranged on the extended portion of the substrate;
a flexible circuit substrate including a signal line electrically connected to the driving chip and a conductive cover layer covering the driving chip, the driving chip receiving signals from an outside through the signal line of the flexible circuit substrate and transmitting said signals to the display unit.
10. The display apparatus of claim 9 , the extended portion of the substrate comprising a plurality of signal wires electrically connected to the driving chip and the display unit.
11. The display apparatus of claim 9 , the conductive cover layer to block electromagnetic waves generated in a vicinity of the driving chip and prevent said electromagnetic waves from reaching the display unit.
12. The display apparatus of claim 9 , the conductive cover layer being an electromagnetic shield that prevents electromagnetic interference produced in a vicinity of the driving chip from reaching the display unit.
