Display apparatus with inspection and method of manufacturing the same
View Patent ↗A display apparatus has an insulating substrate, a signal line for transmitting a signal to a pixel formed in a display area on the insulating substrate, a driver integrated circuit (IC) mounted outside of the display area of the insulating substrate and electrically connected to the signal line, and an inspection pad formed outside of the display area and electrically connected to the signal line. The inspection pad is covered with resin.
1. A display apparatus, comprising:
an insulating substrate;
a signal line for transmitting a signal to a pixel formed in a display area composed of pixels on the insulating substrate;
a driver integrated circuit (IC) mounted outside of the display area of the insulating substrate and electrically connected to the signal line;
an inspection pad formed outside of the display area of the insulating substrate, electrically connected to the signal line, and covered with a resin; and
a wiring substrate for inputting a signal from outside to the driver IC,
wherein the wiring substrate and a signal input pad are electrically connected by an anisotropic conductive film, and
the wiring substrate covers the signal input pad, but the wiring substrate does not cover the inspection pad.
2. A display apparatus according to claim 1 , wherein the resin is selected from the group consisting of silicon, acryl, urethane, epoxy, and polyimide.
3. A display apparatus according to claim 1 , wherein the resin is the anisotropic conductive film.
4. A display apparatus according to claim 1 , further comprising:
a conductive extension line connecting the signal line and the driver IC to the inspection pad.
5. A display apparatus according to claim 2 , further comprising:
a conductive extension line connecting the signal line and the driver IC to the inspection pad.
6. A display apparatus according to claim 3 , further comprising:
a conductive extension line connecting the signal line and the driver IC to the inspection pad.
7. A display apparatus according to claim 1 , wherein the wiring substrate is a flexible substrate.
8. A display apparatus according to claim 1 , wherein the anisotropic conductive film is formed on the inspection pad and the anisotropic conductive film on the inspection pad is coated with the resin.
9. A display apparatus according to claim 8 , wherein the resin is selected from the group consisting of silicon, acryl, urethane, epoxy, and polyimide.
10. The display apparatus according to claim 1 , wherein the inspection pad is covered with the anisotropic conductive film that is covered with the resin.
