Description

BACKGROUND


Technical Field



[0001] The present disclosure relates to an image processing apparatus, and in particular, to a display.

Related Art



[0002] With rapid development of display technologies, displays are widely applied to human life and play an increasingly important role. For example, displays, as display interfaces, may be applied to various fields such as motion monitoring, domestic life, healthcare, and vehicle traffic. Currently, shapes of conventional displays are often designed into in a square shape or a rectangular shape instead of being adaptively designed according to requirements of users. Therefore, when shapes of displays are directly designed according to requirements of users, jaggies may occur on edges of the displays, resulting in defects on appearances of the displays. Hence, the user experience may be greatly affected.

[0003] As can be seen, inconvenience and disadvantages still exist in the foregoing existing manner and need to be overcome. To resolve the foregoing problem, efforts have been made for solutions in related fields. However, no appropriate solution has been developed for a long time.

SUMMARY



[0004] An embodiment disclosed in the present disclosure relates to a display. The display includes a plurality of first pixels, a plurality of second pixels and a light-shielding unit. The second pixels are disposed around the first pixels. The light-shielding unit is disposed around the second pixels. Each of the second pixels is a white pixel, and the second pixels are sandwiched between the light-shielding unit and the first pixels.

[0005] Based on the above, as compared with the prior art, the technical solution in the present disclosure has apparent advantages and beneficial effects. By means of the technical solution above, a great technical progress may be achieved, and the present disclosure has a value of being widely applied to the industry. In the display disclosed in the present disclosure, the first pixels are sequentially surrounded by the light-shielding unit and the second pixels, and the second pixels are sandwiched between the light-shielding unit and the first pixels. In addition, the second pixels are configured as white pixels. Therefore, the display disclosed in the present disclosure not only can effectively reduce jaggies on edges of a display, but also can reduce rainbow veins on edges of a display that are generated because of use of a light-shielding unit, thereby improving quality of experience of users.

In this embodiment, each of the second pixels 120 is a white pixel, and the second pixels 120 are sandwiched between the light-shielding unit 130 and the first pixel 110.

[0011] In an embodiment, the first pixels 110 are adjacent to each other, and the second pixels 120 are adjacent to each other. For example, referring to FIG. 1A, because the first pixels 110 are adjacent to each other, there is no gap between different first pixels 110.
