In the drawings, elements having similar structures are denoted by the same reference numerals.
Fig. 1 is a schematic plan view of a display panel according to the present invention, wherein the display panel includes a display area 201 and a non-display area 202 located at the periphery of the display area 201, and the display area 201 is used for displaying an image.
The display panel further comprises a power line, wherein the power line comprises a first portion located in the display area 201 and a plurality of transmission portions 208 located on the bending area 204, and the transmission portions 208 are arranged on the bending area 204 at intervals.
In the display panel of the present invention, the non-display region 202 includes a first region 206 located on a side of the bending region 204 away from the display region 201, and a second region 205 located between the display region 201 and the bending; wherein the power line includes at least one first voltage uniforming portion 211 located in the first region 206 and at least one second voltage uniforming portion 212 located in the second region 205, and the number of the plurality of transmission portions 208 is greater than the number of the first voltage uniforming portions 211.
In the present embodiment, the number of the first voltage uniforming portions 211 is 1, that is, the power supply line located in the first region 206 is a thicker one for reducing the voltage drop; in addition, the plurality of transmission portions 208 of the plurality of bending regions 204 are arranged to improve the voltage drop of the power line between the driving chip 203 and the display region 201, thereby improving the display uniformity of the display panel.
In this embodiment, the power line is a VDD signal line; it can be understood that, compared with the prior art, the VDD signal line of the present invention includes a first VDD voltage uniforming portion located in the first region 206, a second VDD voltage uniforming portion located in the second region 205, and a plurality of transmission portions 208 located in the bent region 204; as can be appreciated, the first VDD voltage uniforming portion is connected to the second VDD voltage uniforming portion through the plurality of transmission portions 208;
compared with the prior art, the first voltage uniform part 211 of a part of the VDD signal line is arranged in the first area of the non-display area far away from the bending area 204, so that the width of the second voltage uniform part 212 between the display area and the bending area is reduced, and the design of a narrow lower frame is achieved; since the total area of the VDD signal lines is constant and the lower frame is narrower, the area of the first VDD voltage uniforming portion located in the first region 206 is larger than the area of the second VDD voltage uniforming portion located in the second region 205 in the present invention; and, in a direction from the first region 206 to the bent region 204, a width of the second VDD voltage uniforming portion is smaller than a width of the first VDD voltage uniforming portion.
In the display panel of the present invention, the display panel further includes data lines extending from the display region 201 to the non-display region 202; wherein the data lines and the plurality of transmission portions 208 of the power lines are alternately arranged in the bending region 204.
The data line of the invention extends from the display area 201 to the non-display area 202 and is electrically connected with the driving chip 203 in the non-display area 202; in the non-display region 202, the data lines include a first fan-out data line 213 located in the first region 206, a second fan-out data line (not shown) located in the second region 205, and a third fan-out data line 209 located in the bending region 204; the second fan-out data line is connected with the first fan-out data line 213 across a bridge through the third fan-out data line 209;
it is understood that when the data line is transmitted from the display area 201 to the second area 205, the data line is switched from the source/drain layer to the gate layer, and data transmission is performed through the metal layer of the gate layer; since the metal material of the existing gate layer is generally molybdenum metal, the metal material of the source drain layer is titanium aluminum titanium, and the metal flexibility of the titanium aluminum titanium is not easy to break due to molybdenum when being bent, when the data line is transmitted to the bending region 204, the line needs to be changed again to the source drain layer with better metal flexibility; after the data line passes through the bending region 204, the line is changed to the gate layer again;
it is understood that the first fan-out data line 213 and the second fan-out data line are the same metal layer, and the third fan-out data line 209 and the first fan-out data line 213 and the second fan-out data line are different metal layers.
In addition, the data line is a source drain layer in the bending region 204, and the VDD signal line in the present invention is disposed in the same layer as the data line in the display region 201; therefore, in the bending region 204, the data line and the VDD signal line cannot intersect, and both of them need to be insulated in the bending region 204; preferably, the plurality of transmission portions 208 and the third fan-out data lines 209 are alternately arranged in the present invention.
It can be understood that, compared with the prior art, since the second fan-out data line in the second region 205 and the second VDD voltage uniform part are different metal layers, the second VDD voltage uniform part is stacked, and the distance from the display region 201 to the bending region 204 is further reduced.
In addition, the non-display area 202 further includes a test circuit 214, and the first fan-out data line 213 is electrically connected to the driving chip 203 through the test circuit 214.
As shown in fig. 1, the display panel further includes VSS signal lines 210, where the VSS signal lines 210 are disposed outside the non-display region 202, i.e., near an outer frame of the display panel; the VSS signal line 210 extends from the display region 201 to the end of the driving chip 203 through the bending region 204;
it can be understood that the VSS signal line 210 and the VDD signal line are disposed in the same layer, that is, the VSS signal line 210 and the VDD signal line 207 are the same metal layer as the source and drain in the display panel; preferably, the VSS signal line 210 and the VDD signal line in this embodiment are made of titanium aluminum titanium;
since the VSS signal line 210 and the VDD signal line are made of the same metal layer, the VSS signal line 210 and the VDD signal line 207 need to be insulated when the display panel is arranged in a flat line.
It is understood that the power line in the present invention is not limited to the VDD signal in the above embodiment.
It can be understood that the present invention achieves the design of a narrow lower frame by disposing the first voltage uniforming portion 211 of a part of the power line in the first region of the non-display region away from the bending region 204, thereby reducing the width of the second voltage uniforming portion 212 between the display region and the bending region; in addition, since the second fan-out data line and the second voltage equalizing part 212 in the second region 205 are different metal layers, the second voltage equalizing part 212 is disposed above the second fan-out data line, and the distance between the display region 201 and the bending region 204 is further reduced.
The invention provides a display panel, which comprises a display area and a non-display area, wherein the non-display area comprises a bending area; a power line including a first portion positioned on the display region and a plurality of transmission portions positioned on the bending region, wherein the plurality of transmission portions are disposed at intervals on the bending region; according to the invention, part of power signal wires are arranged in the bending area and the extension section of the bending area, and the second fan-out data wire is arranged below the second voltage uniform part, so that the distance between the display area and the bending area is reduced, and the lower frame of the display panel is further reduced.
In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, therefore, the scope of the present invention shall be determined by the appended claims.
