Referring to
In this embodiment, each of the at least one first opening 11 is surrounded by three of the second openings 12.
In this embodiment, the display screen 200 further includes a color film layer on the substrate. The light-shielding layer 30 is disposed on the color film layer. For example, the light-shielding layer 30 can be disposed on a cover plate layer or under a polarizer layer.
Because metal traces such as data lines or scan lines connect neighboring pixels, diffraction is generated when light passes through the metal traces. Accordingly, the present invention disposes the light-shielding layer 30 on a region that generates the diffraction, disposes the at least one first opening 11 for allowing external light to enter the display screen 200 and the at least one second opening 12 for allowing light emitted by the pixels to enter an external side on the light-shielding layer 30, and the light-shielding layer 30 blocks the metal traces connecting neighboring pixels to prevent metal traces from generating the diffraction.
The first display region 10 in the display screen 200 of the present invention is mainly used for the transmission of the external light, a distance between neighboring pixels in the conventional second display region 20 is short, and a corresponding light receiving unit 401 cannot accurately obtain a corresponding optical signal due to a less amount of the transmission of the external light. Accordingly, the present invention increases a distance between neighboring pixels in the first display region 10 to increase an amount of the external light passing through the at least one first opening 11.
Referring to
In this embodiment, in a direction from a center of the first display region 10 to the second display region 20, a distance between two neighboring pixels is equal.
Referring to
Because the pixel density of the first display region 10 is less than the pixel density of the second display region 20, a resolution of the first display region 10 is less than a resolution of the second display region 20. When the display screen 200 displays an image, users may observe that the image of a partial region is unclear when a sudden change occurs from the second display region 20 to the first display region 10, thereby reducing a user experience.
Accordingly, in the direction from the center of the first display region 10 to the second display region 20, the present invention gradually reduces the distance between two neighboring pixels, so that the resolution of the first display region 10 is gradually reduced, ensuring the user experience.
In this embodiment, the first display region 10 includes a boundary region near the second display region 20. A distance between two neighboring pixels in the boundary region is equal to a distance between two neighboring pixels in the second display region 20.
