Abstract

Disclosed is a display device including: a display panel on which a plurality of driver chips are mounted by using a COG configuration; a signal substrate on which a timing controller for generating a differential signal inputted into each of the driver chips is formed; and a connecting substrate which connects the plurality of driver chips with the timing controller, wherein the connecting substrate includes a first connecting substrate on which a first line for inputting the differential signal into a driver chip excluding a driver chip located at a terminating area is formed and a second connecting substrate on which a second line for inputting the differential signal into the driver chip located at the terminating area, and wherein a termination resistor connects the second line for transmitting the differential signal which is formed on the second connecting substrate.

Claims (14)

1. A display device, comprising:

a display panel on which a plurality of driver chips are mounted by using a COG configuration;

a signal substrate on which a timing controller for generating a differential signal inputted into each of said driver chips is formed; and

a connecting substrate which connects said plurality of driver chips with said timing controller,

wherein said connecting substrate includes a first connecting substrate on which a first line for inputting said differential signal into a driver chip excluding a driver chip located at a terminating area is formed and a second connecting substrate on which a second line for inputting said differential signal into said driver chip located at said terminating area, and wherein a termination resistor connects said second line for transmitting said differential signal which is formed on said second connecting substrate.

2. The display device according to claim 1 , wherein

said second line for inputting said differential signal into said driver chip located at said terminating area is formed on said first connecting substrate.

3. The display device according to claim 1 , wherein

a plurality of termination resistors are formed on said second connecting substrate and

said plurality of termination resistors are arranged so that distances between each of said plurality of termination resistors and said driver chip located at said terminating area become substantially equal to each other.

4. The display device according to claim 1 , wherein said display device is a liquid crystal display.

5. The display device according to claim 1 , wherein said display device is an organic EL display.

6. The display device according to claim 1 , wherein said second connecting substrate is a flexible substrate.

7. The display device according to claim 1 , wherein said first connecting substrate and said second connecting substrate are made of the same material.
