Abstract

The present invention provides a display panel, which includes active area and vacant area surrounding the active area, and dummy pattern area without display functionality being disposed along boundary between active area and vacant area. The present invention also provides a manufacturing method of display panel and a panel display device. The present invention disposes dummy pattern area along boundary active area to withstand loading effect and to ensure active area is not affected by loading effect and display patterns are normal and uniform.

Claims (14)

1. A display panel, comprising an active area and a vacant area surrounding the active area, and a dummy pattern area without display functionality being along boundary between the active area and the vacant area;

the active area, the vacant area and the dummy pattern area are disposed on pattern layers of the display panel for lithography or etching in a wet process, and the pattern layers comprise: a pixel electrode layer, a first metal layer and a second metal layer;

the active area and the dummy pattern area are disposed on the pixel electrode layer and the dummy pattern area comprises a plurality of dummy pixels;

the active area comprises a plurality of pixels having normal pattern design, and pattern design of the dummy pixels is identical to the normal pattern design of the pixels, and pattern of the dummy pixels near the vacant area is an irregular pattern;

wherein the irregular pattern is generated from solution concentrations being existing at an intersection area of the dummy pattern area and the active area, at the active area, and at the dummy pattern area, and the solution concentration at the dummy patter area gradually decreases from the intersection area towards the vacant area during the wet process.

2. The display panel as claimed in claim 1 , characterized in that the solution-concentration at the active area stays unchanged.

3. A panel display device, which comprises a display panel, the display panel comprising: an active area and a vacant area surrounding the active area, and a dummy pattern area without display functionality being along boundary between the active area and the vacant area;

the active area, the vacant area and the dummy pattern area are disposed on pattern layers of the display panel for lithography or etching in a wet process, and the pattern layers comprise: a pixel electrode layer, a first metal layer and a second metal layer;

the active area, the vacant area and the dummy pattern area are disposed on the pixel electrode layer and the dummy pattern area comprises a plurality of dummy pixels;

the active area comprises a plurality of pixels having normal pattern design, and pattern design of the dummy pixels is identical to the normal pattern design of the pixels and pattern of the dummy pixels near the vacant area is an irregular pattern;

wherein the irregular pattern is generated from solution concentrations being existing at an intersection area of the dummy pattern area and the active area, at the active area, and at the dummy pattern area, and the solution concentration at the dummy patter area gradually decreases from the intersection area towards the vacant area during the wet process.

4. The panel display device as claimed in claim 3 , characterized in that solution concentration at the active area stays unchanged.

5. The display panel as claimed in claim 1 , characterized in that a first solution concentration at an intersection area of the dummy pattern area and the active area is equal to a second solution concentration at the active area, and a third solution concentration at the dummy pattern area gradually decreases from the intersection towards the vacant area to form the irregular pattern at the dummy pixel area.

6. The panel display device as claimed in claim 3 , characterized in that a first solution concentration at an intersection area of the dummy pattern area and the active area is equal to a second solution concentration at the active area, and a third solution concentration at the dummy pattern area gradually decreases from the intersection towards the vacant area to form the irregular pattern at the dummy pixel area.
