Abstract

An active device array structure including a substrate including a first region and a second region, and first signal lines, second signal lines, third signal lines, and active devices disposed on the substrate is provided. A bending degree of the first region is greater than that of the second region. The first signal lines and the second signal lines cross through the first region and the second region. Each first signal line includes a first multi-segments structure located in the first region. Each first multi-segments structure includes first segments connected in parallel. An extending direction of the third signal lines is intersected with the first signal lines and the second signal lines. Each third signal line is electrically connected to one first signal line. The active devices are electrically connected to the second and the third signal lines, or the first and the third signal lines.

First claim

a substrate, having a first region and a second region, wherein a bending degree of the first region is greater than a bending degree of the second region;
a plurality of first signal lines, disposed on the substrate, wherein each of the first signal lines crosses through the first region and the second region and comprises at least one first multi-segments structure, and the first multi-segments structure is located in the first region and comprises a plurality of first segments electrically connected in parallel;
a plurality of second signal lines, disposed on the substrate, wherein each of the second signal lines crosses through the first region and the second region and is electrically independent from the first signal lines;
a plurality of third signal lines, disposed on the substrate, wherein an extending direction of the third signal lines is intersected with the first signal lines and the second signal lines and each of the third signal lines is electrically connected and conductive to one of the first signal lines or one of the second signal lines; and
a plurality of active devices, disposed on the substrate, wherein each of the active devices is electrically connected to said one of the second signal lines and one of the third signal lines when said each of the third signal lines is electrically connected to said one of the first signal lines, or each of the active devices is electrically connected to said one of the first signal lines and one of the third signal lines when said each of the third signal lines is electrically connected to said one of the second signal lines.

2. The active device array structure as recited in claim 1 , wherein the first signal lines transmit a data signal, and the second signal lines transmit a scan signal.

3. The active device array structure as recited in claim 1 , wherein the first signal lines transmit a scan signal, and the second signal lines transmit a data signal.

4. The active device array structure as recited in claim 1 , wherein each of the first signal lines further comprises at least one single-segment structure, and the single-segment structure and the first multi-segments structure are connected in turn along an extending direction of the first signal lines.

5. The active device array structure as recited in claim 4 , wherein the first multi-segments structure comprises N first segments connected in parallel, a line width of the single-segments structure is N times a line width of one of the N first segments, and N is an integer greater than 1.

6. The active device array structure as recited in claim 1 , wherein each of the at least one first multi-segments structure is located between adjacent two of the third signal lines.

7. The active device array structure as recited in claim 1 , wherein adjacent two of the first segments of each of the at least one first multi-segments structure are separated by an opening.

8. The active device array structure as recited in claim 7 , wherein a shape of the opening comprises a rectangle or a rhombus.
