Abstract

A display panel comprises a first substrate, a second substrate, and an active switch matrix. The first substrate comprises color resistor units, and the second substrate is disposed opposite to the first substrate. The active switch matrix is disposed on the first substrate or the second substrate. The active switch matrix comprises scan lines and data lines. A first repair line is disposed on one side of at least one of the scan lines, and a second repair line is disposed on one side of at least one of the data lines.

Claims (27)

1. A display panel, comprising:

a first substrate comprising color resistor units;

a second substrate disposed opposite to the first substrate; and

an active switch matrix disposed on the first substrate or the second substrate;

wherein the active switch matrix comprises scan lines and data lines, a first repair line is disposed on one side of at least one of the scan lines, and a second repair line is disposed on one side of at least one of the data lines,

wherein the first repair lines are disposed in correspondence with the scan lines in different layers, and the second repair lines are disposed in correspondence with the data lines in different layers,

wherein a ratio of the number of the first repair lines to the number of the scan lines is smaller than one and greater than or equal to one half, the first repair lines are disposed in an equidistant manner,

wherein a ratio of the number of the second repair lines to the number of the data lines is smaller than one and greater than or equal to one half, the second repair lines are disposed in an equidistant manner.

2. The display panel according to claim 1 , wherein the active switch matrix is disposed on the second substrate.

3. The display panel according to claim 1 , wherein the active switch matrix is disposed on the first substrate, and the color resistor units are formed on the active switch matrix.

4. The display panel according to claim 1 , wherein the first repair lines and the second repair lines are disposed in one layer or different layers.

5. The display panel according to claim 1 , further comprising:

a repair detection module coupled to the active switch matrix and detecting trace conditions of the scan lines or the data lines; and

a repair positioning module coupled to the active switch matrix and the repair detection module, and positioning a specific position of the scan line or the data line with a trace problem.

6. A method of repairing a display panel, the display panel comprising a first substrate and a second substrate disposed opposite to the first substrate, the first substrate comprising color resistor units, an active switch matrix disposed on the first substrate or the second substrate, the active switch matrix comprising scan lines and data lines, and the method comprising steps of:

correspondingly disposing a first repair line on one side of at least one of the scan lines, and correspondingly disposing a second repair line on one side of at least one of the data lines;

looking for an opened scan line or an opened data line; and

respectively bridging two ends of the opened scan line or the opened data line with the first repair line and the second repair line to form an electroconductive pathway,

wherein the first repair lines are disposed in correspondence with the scan lines in different layers, and the second repair lines are disposed in correspondence with the data lines in different layers, and

wherein a ratio of the number of the first repair lines to the number of the scan lines is smaller than one and greater than or equal to one half, the first repair lines are disposed in an equidistant manner,

wherein a ratio of the number of the second repair lines to the number of the data lines is smaller than one and greater than or equal to one half, the second repair lines are disposed in an equidistant manner.

7. The method according to claim 6 , wherein the step of respectively bridging the two ends of the opened scan line or the opened data line with the first repair line and the second repair line to form the electroconductive pathway comprises: bridging the scan line or the data line with the corresponding first repair line and second repair line by way of laser bonding.

8. The method according to claim 6 , wherein the active switch matrix is disposed on the second substrate.

9. The method according to claim 6 , wherein the active switch matrix is disposed on the first substrate, and the color resistor units are formed on the active switch matrix.

10. The method according to claim 6 , wherein the display panel further comprises:

a repair detection module configured to detect trace conditions of the scan lines or the data lines; and

a repair positioning module configured to position a specific position of the scan line or the data line with a trace problem.
