That is, the light-out adjusting element 30 is disposed at both the light-out side of the first pixel 11 adjacent to the second display area 20 and the light-out side of the second pixel 21 adjacent to the first display area 10, so that the transition between the first display area 10 and the second display is natural.

In an embodiment of the present application, as shown in fig. 2, the light-emitting adjustment element 30 includes a colorization layer 31 and a light-suppressing layer 32, the colorization layer 31 and the light-suppressing layer 32 are arranged in a same layer, and a ratio of an area occupied by each of the colorization layer 31 and the light-suppressing layer 32 is related to a distance between the corresponding first pixel 11 and the corresponding second pixel 21 and a boundary between the first display area 10 and the second display area 20. In other embodiments, as shown in fig. 3, each of the light-emitting adjusting elements 30 is disposed on the light-emitting side of the first pixel 11, and includes a colorization layer 31 and a light-suppressing layer 32 disposed on the first pixel 11, the colorization layer 31 and the light-suppressing layer 32 are disposed in a layer-by-layer manner, and the ratio of the area occupied by each of the colorization layer 31 and the light-suppressing layer 32 is related to the distance from the corresponding first pixel 11 to the boundary between the first display area 10 and the second display area 20. As shown in fig. 4, each of the light-emitting adjustment elements 30 is disposed on the light-emitting side of the second pixel 21, and includes a colorization layer 31 and a light-suppressing layer 32 disposed on the second pixel 21, the colorization layer 31 and the light-suppressing layer 32 are disposed in a same layer, and the ratio of the area occupied by each of the colorization layer 31 and the light-suppressing layer 32 is related to the distance from the corresponding second pixel 21 to the boundary between the first display area 10 and the second display area 20.
In this embodiment of the application, the colorization layer 31 can strengthen the light-emitting rate of the pixel corresponding to the display area, and improve the light-emitting intensity, specifically, in this embodiment of the application, the colorization layer 31 can be a quantum dot layer, and the quantum dot layer is arranged on the light-emitting side through the first pixel 11 or the second pixel 21, so that the quantum dot can be excited to emit light, and the light-emitting intensity can be improved. In another embodiment, the colorization layer 31 may also be a color filter layer, and the color filter layer can reduce the problem of light intensity reduction caused by the intrusion of the external environment light. The light-suppressing layer 32 can reduce the light-emitting rate of the pixels corresponding to the display area, thereby reducing the light-emitting intensity. By providing the light-suppressing layer 32, light emitted by a pixel of the display area is scattered and refracted at the light-suppressing layer 32 when passing through the light-suppressing layer 32, so that the light intensity is reduced.
In the embodiment of the present application, one light emitting adjustment unit includes both the colorization layer 31 and the light-suppressing layer 32, and the display transition between the boundaries between the first display area 10 and the second display area 20 is controlled by controlling the ratio of the areas occupied by the colorization layer 31 and the light-suppressing layer 32. For example, in the embodiment of the present application, the colorization layer 31 can enhance the light intensity by 40%, and the light suppression layer 32 can reduce the light intensity by 70%, for example, when the colorization layer 31 and the light suppression layer 32 respectively occupy 50%, the ratio of the light intensity of the light emitted through the light emission adjustment unit to the light intensity of the light emitted without the light emission adjustment unit is 50% × (1 + 40%) +50 × (% (1-70%) =85%; if the colored layer 31 occupies 20% and the light-suppressing layer 32 occupies 80%, the ratio of the light-emitting intensity passing through the light-emitting adjusting unit to the light-emitting intensity without the light-emitting adjusting unit is 20% × (1 + 40%) +80% × (1-70%) =52%. By controlling the ratio of the area occupied by each of the colorization layer 31 and the light-suppressing layer 32, the light-emitting intensity of the first pixel 11 and/or the second pixel 21 can be conveniently regulated, so that the first pixel 11 and the second pixel 21 display transition naturally. The ratio of the area occupied by each of the colorization layer 31 and the light-suppressing layer 32 is related to the distance of the corresponding first pixel 11 or second pixel 21 from the boundary between the first display region 10 and the second display region 20, so as to adjust for making the transition between the first display region 10 and the second display region 20 natural.
In another embodiment, the light-emitting adjusting element 30 is disposed only on the light-emitting side of the second pixels 21, and the light-emitting adjusting element 30 may also include only the light-suppressing layer 32, so as to control the light-emitting rate by controlling the thickness of the light-suppressing layer 32. When the light-suppressing layer 32 is thick, light emitted by the second pixels 21 of the second display area 20 passes through the light-suppressing layer 32, and is greatly influenced by scattering and refraction, and the light-emitting rate is low; when the thickness of the light-suppressing layer 32 is small, light emitted from the second pixel 21 of the second display area 20 passes through the light-suppressing layer 32, and is less affected by scattering and refraction, and the light-emitting rate is less attenuated.
In the embodiment of the present application, as shown in fig. 2, the light exit adjusting elements 30 are disposed near the boundary between the first display area 10 and the second display area 20, and the area ratio of the colorizing layer 31 to the light-suppressing layer 32 gradually increases from the first display area 10 to the adjacent second display area 20, and gradually decreases from the second display area 20 to the adjacent first display area 10. In the embodiment of the present application, the light emitting adjustment element 30 is disposed near the boundary between the first display area 10 and the second display area 20, and the light emitting adjustment element 30 is disposed near the boundary between the first display area 10 and the second display area 20, so that the transition between the first display area 10 and the second display area 20 is natural, specifically, in the embodiment of the present application, a part of the light emitting adjustment element 30 is disposed on three sets of first pixels 11 facing the first display area 10 at the boundary, a part of the light emitting adjustment element 30 is disposed on two sets of first pixels 11 facing the first display area 10 at the boundary, and the light emitting adjustment element 30 is disposed on three sets of second pixels 21 facing the second display area 20 at the boundary. In other embodiments, the light-exiting adjusting elements 30 may also be disposed on one or two or four or more groups of the first pixels 11 facing the first display area 10 at the boundary, and the light-exiting adjusting elements 30 are disposed on one or two or four or more groups of the second pixels 21 facing the second display area 20 at the boundary. The light emitting rate and the light emitting intensity are controlled by controlling the area ratio of the colorization layer 31 to the light suppression layer 32, so that the transition between the first display area 20 and the second display area 20 is natural. Specifically, in the embodiment of the present application, by arranging the first display area 10 to have the area ratio of the colorization layer 31 and the light-suppressing layer 32 in the direction adjacent to the second display area 20 gradually increased, the light-emitting rate of the first display area 10 gradually increases in the direction toward the boundary of the second display area 20, and the brightness gradually increases, so that a gradual transition can be formed between the brighter second display area 20 and the darker first display area 10. By gradually reducing the area ratio of the colorization layer 31 and the light-suppressing layer 32 in the second display area 20 to the direction adjacent to the first display area 10, the light-emitting rate of the second display area 20 in the direction toward the boundary of the first display area 10 is gradually reduced, and the brightness is gradually reduced, so that a gradual transition can be formed between the brighter second display area 20 and the darker first display area 10.

Specifically, in the embodiment of the present application, by controlling the area ratio of the colorization layer 31 to the light-suppressing layer 32 in each region to be the same, and gradually increasing the colorization layer 31 and the light-suppressing layer 32 in several regions, the luminance between the first display region 10 and the second display region 20 can form a uniform gradual transition.
The area ratio of the colorization layer 31 to the light-suppressing layer 32 gradually decreases from the second display area 20 to the adjacent first display area 10, and the area ratio of the colorization layer 31 to the light-suppressing layer 32 of all the light-emitting adjusting elements 30 in each area is the same.
