Abstract

The present application discloses a display panel and a display device. The display panel includes a non-display region and a gate driver on array (GOA) unit region in the non-display region. The GOA unit region includes multi-level GOA units arranged in multiple columns, thereby improving a space limitation problem associated with arranging a plurality of GOA units in a display panel while the display panel achieves high resolution.

Claims (35)

1. A display panel, comprising a display region and a non-display region disposed at a periphery of the display region, a gate driver on array (GOA) unit region being disposed in the non-display region,

wherein multi-level cascaded GOA units are arranged in the GOA unit region, the GOA unit region comprises a first GOA unit region and a second GOA unit region, and odd-numbered GOA units of the multi-level cascaded GOA units are arranged in the first GOA unit region and are arranged in n rows and m columns, and n>1, and m>1,

even-numbered GOA units of the multi-level cascaded GOA units are arranged in the second GOA unit region and are arranged in x rows and y columns, x>1 and y>1,

wherein the first GOA unit region comprises a first subregion and a second subregion, and wherein n1 rows

and m1 columns of the odd-numbered GOA units are arranged in the first subregion, an electrostatic discharge protective circuit and n2 rows and m2 columns of the odd-numbered GOA units are arranged in the second subregion, the electrostatic discharge protective circuit is connected to each of the multi-level cascaded GOA units, and n1>1, m1>1, n2>1 and m2>1.

2. The display panel according to claim 1 , wherein

a GOA unit at an i-th row and a j-th column in the first GOA unit region is G 2m(i−1)+2j-1 .

3. The display panel according to claim 1 , wherein

a GOA unit at a z-th row and a w-th column in the second GOA unit region is G 2y(z−1)+2w .

4. The display panel according to claim 1 , wherein

a GOA unit at an i-th row and a j-th column in the first GOA unit region is G 2m(i−1)+2j-1 , and a GOA unit at a (i+1)-th row and the j-th column in the first GOA unit region is G 2m(i+1)−2j+1 , wherein i is an odd number.

5. The display panel according to claim 1 , wherein

a GOA unit at a z-th row and a w-th column in the second GOA unit region is G 2y(z−1)+2w , and a GOA unit at a (z+1)-th row and the w-th column in the second GOA unit region is G 2y(z+1)−2w+2 , wherein z is an odd number.

6. The display panel according to claim 1 , wherein the non-display region comprises a first non-display region and a second non-display region, which are disposed on two opposite sides of a display region of the display panel; and

the first GOA unit region is positioned in the first non-display region, and the second GOA unit region is positioned in the second non-display region.

7. The display panel according to claim 1 , wherein at least two columns of the multi-level cascaded GOA units are arranged symmetrically to each other.

8. The display panel according to claim 1 , wherein in the GOA unit region,

a k-th level GOA unit is turned on in response to an output signal of a (k−2)-th level GOA unit and is turned off in response to an output signal of a (k+2)-th level GOA unit, and k is greater than 2.

9. The display panel according to claim 1 , wherein a number of columns of the GOA units in the first subregion is greater than a number of columns of the GOA units in the second subregion.

10. The display panel according to claim 9 , wherein a difference between the number of columns of the GOA units in the first subregion and the number of columns of the GOA units in the second subregion is greater than or equal to 1.

11. The display panel according to claim 1 , wherein the second subregion comprises at least four rows of the GOA units.

12. A display device, comprising a display panel,

wherein the display panel comprises a display region and a non-display region disposed at a periphery of the display region, a gate driver on array (GOA) unit region being disposed in the non-display region, and

wherein multi-level cascaded GOA units are arranged in the GOA unit region, the GOA unit region comprises a first GOA unit region and a second GOA unit region, and odd-numbered GOA units of the multi-level cascaded GOA units are arranged in the first GOA unit region and are arranged in n rows and m columns, and n>1, and m>1,

even-numbered GOA units of the multi-level cascaded GOA units are arranged in the second GOA unit region and are arranged in x rows and y columns, and y>1,

wherein the first GOA unit region comprises a first subregion a second subregion, and wherein n1 rows

m1 columns of the odd-numbered GOA units are arranged in the first subregion, an electrostatic discharge protective circuit and n2 rows and m2 columns of the odd-numbered GOA units are arranged in the second subregion, the electrostatic discharge protective circuit is connected to each of the multi-level cascaded GOA units, and n1>1, m1>1, n2>1 and m2>1.

13. The display device according to claim 12 , wherein

a GOA unit at an i-th row and a j-th column in the first GOA unit region is G 2m(i−1)+2j-1 .

14. The display device according to claim 12 , wherein

a GOA unit at a z-th row and a w-th column in the second GOA unit region is G 2y(z−1)+2w .

15. The display device according to claim 12 , wherein

a GOA unit at an i-th row and a j-th column in the first GOA unit region is G 2m(i−1)+2j-1 , and a GOA unit at a (i+1)-th row and the j-th column in the first GOA unit region is G 2m(i+1)−2j+1 , wherein i is an odd number.
