Problems solved by technology

Since the conventional pixel design is a rectangle, it is necessary to meet the special-shaped display area, so that the periphery of the display area forms arcs, hypotenuses, etc., and the pixels are arranged in a ladder shape according to the shape of the boundary to form a ladder-like edge. These are arranged in a ladder shape The pixels on the edge of the irregular shape can only be approximately curved or hypotenuse, which will cause a strong brightness contrast between the stepped edge of the edge of the display area with display brightness and the completely dark plastic edge area, making the display area The edge of the display panel can be recognized by the human eye, which reduces the visual effect of the edge of the display panel and seriously affects the user experience

[0036] An embodiment of the present invention provides a display panel. In this embodiment, the display panel is a liquid crystal display panel. Of course, in other embodiments of the present invention, the display panel may also be an OLED panel or other display panels. See figure 1 , the display panel includes a display area 100 and a non-display area 200, the display area 100 is the area where the display panel usually displays images, the display area 100 is shaped, that is, non-rectangular, for example, the display area 100 is circular , ellipse, octagon, hexagon and other non-rectangular shapes to meet the needs of different functions. The non-display area 200 is an area where display panel wiring, drivers, etc. are placed. The display panel as a whole may be irregular or rectangular.

[0037] Since the conventional pixel is a rectangle, the display area 100 must be in a different shape, even if the boundary line between the display area 100 and the non-display area 20...

[0049] Figure 6 A display panel provided by the second embodiment of the present invention, Figure 6 structure with figure 1 The structures are similar, so the same reference numerals represent the same components. The main difference between this embodiment and the first embodiment is the number of sub-pixels included in the second pixel unit.

[0050] In this embodiment, the dimmed display area 120 includes a plurality of second pixel units 640, the plurality of second pixel units 640 form multiple rows, and each row includes one or more second pixel units 640, Figure 6 Each row in the figure shows a second pixel unit 640, the second pixel unit 640 includes only one sub-pixel, and the sub-pixel can be a red second sub-pixel, a green second sub-pixel, a blue second sub-pixel, etc. , the second black matrix 240 covers part of the sub-pixels, thereby reducing the aperture ratio of the darkened display area 120 , thereby reducing the brightness of the darkened display area ...

[0052] Figure 7 A display panel provided by the third embodiment of the present invention, Figure 7 structure with figure 1 The structures are similar, so the same reference numerals represent the same components. The main difference between this embodiment and the first embodiment is the darkened display area.

[0053] In this embodiment, the dimmed display area 720 includes a first dimmed display area 721 and a second dimmed display area 722, the first dimmed display area 721 is set adjacent to the normal display area 110, the The second dimmed display area 722 is disposed adjacent to the non-display area 200, the second dimmed display area 722 is located between the non-display area 200 and the first dimmed display area 721, and the first dimmed display area 721 The dark display area 721 is located between the second darkened display area 722 and the normal display area 110, the light transmittance of the second darkened display area 722 is lower than the light transmit...

Abstract

An embodiment of the invention discloses a display panel, which comprises a normal display area, a darkening display area and a non-display area, wherein the normal display area comprises multiple first pixel units; the darkening display area is arranged around the normal display area, and comprises multiple second pixel units; the non-display area is arranged around the darkening display area; the light transmittance of the non-display area is less than that of the darkening display area; the light transmittance of the darkening display area is less than that of the normal display area. The embodiment of the invention also discloses a display device. By adopting the display panel, the display panel has the advantages that the visual impression of the edge of a display area can be ameliorated, and the user experience is improved.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular, relates to a display panel and a display device. Background technique [0002] With the development of smart technology, wearable devices are becoming more and more popular, and with the development of wearable electronic products, the human-computer interaction interface of these wearable devices no longer uses traditional rectangular panels, but more and more uses The panels of the special-shaped display area (generally, the panels are also special-shaped), including shapes such as circles, ovals, octagons, and hexagons, to meet the wearable performance of smart devices, or to meet their fashionable appearance design. [0003] However, there are at least the following problems in the prior art: the display panel includes a display area (ie, a pixel area), a black matrix area, and a plastic border area. Of course, in order to avoid light leakage, the plastic border area also ...
