AI Technical Summary

Technical Problem

In the manufacturing process of existing organic light-emitting diode (OLED) displays, the top black matrix layer in the display edge area is relatively low due to the packaging process. This results in poor privacy protection and high brightness, affecting both privacy protection and uneven display performance.

Method used

By dividing the display panel into a central display area and an edge display area, and setting multiple edge sub-areas within the edge display area, adjusting the opening width of the privacy pixels and the thickness of the encapsulation layer, the privacy opening width of the edge sub-areas far from the central display area is smaller than that of the edge sub-areas near the central display area, and the privacy pixel opening widths within the same edge sub-area are the same, thereby improving the uniformity of the display transition.

Benefits of technology

It achieves uniform brightness between the edge display area and the center display area, reduces the risk of light-dark boundary caused by non-uniform transition, and improves the consistency of privacy protection and display effect.

Abstract

The application discloses a display panel and a display device, wherein the thickness of the encapsulation layer decreases from the center display area to the edge of the edge display area, in any two adjacent edge sub-areas, the width of the anti-peep opening of the first anti-peep pixel in the edge sub-area far from the center display area is smaller than the width of the anti-peep opening of the first anti-peep pixel in the edge sub-area close to the center display area, and the width of the anti-peep opening of the first anti-peep pixel in the same edge sub-area is the same. The embodiment of the application divides the first edge area, the corner transition area and the second edge area as a whole into multiple edge sub-areas, sets the first anti-peep pixel with a smaller anti-peep opening in the edge sub-area with a lower terrain, and the anti-peep opening of the first anti-peep pixel in the same edge sub-area is the same, so as to improve the uniformity of the display transition of the first edge area and the second edge area, and reduce the risk of bright-dark division caused by non-uniform transition.
