Technical Field

Background

Glare may be defined as the substantially specular reflection of ambient light at one or more surfaces of a transparent medium on the viewer side of the transparent medium. When the optical path of the glare and the optical path of the object light substantially overlap in the region between the transparent medium and the observer, the glare makes it difficult for the observer to observe the object through the intervening transparent medium, and thus, there is a need for an antiglare measure that reduces the glare.

Among them, an antiglare effect can be achieved by AG (Anti-glare glass) antiglare/antiglare scattering treatment, however, when AG antiglare/antiglare scattering surfaces are employed in a transparent medium based on the treatment, a flash point (spark) is generally generated, which affects the visual effect of the observer.

Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The paper-like screen is mainly used for education, eye protection and other application scenes, and the paper-like screen has the following advantages by combining information display characteristics of the paper shown in FIG. 1:

1. the general texture of paper: the appearance is soft, comfortable, clean and fresh. The screen has high diffuse reflection and low specular reflection, and has excellent in-plane brightness, color, contrast uniformity and viewing angle contrast uniformity.

3. Immersion visual experience: the color is warm and natural, and the immersion feeling of different environments is strong. The screen has the consistency of visual angle contrast and adjustable brightness and color temperature along with the ambient light.

4. Excellent interaction experience: the pen is convenient to record and mark, and has excellent touch feeling and pen writing texture. The screen supports the active pen and has excellent writing friction feeling and touch feeling.

Glare may be defined as the substantially specular reflection of ambient light at one or more surfaces of a transparent medium on the viewer side of the transparent medium. When the optical path of the glare and the optical path of the object light substantially overlap in the region between the transparent medium and the observer, the glare makes it difficult for the observer to observe the object through the intervening transparent medium, and thus, there is a need for an antiglare measure that reduces the glare. The anti-dazzle effect can be achieved through AG anti-dazzle/anti-light scattering treatment, and the principle is that the glass is subjected to process treatment on one side or two sides, so that the glass has lower reflectance compared with common glass, the interference of ambient light is reduced, the reflection of light of a screen is reduced, and the anti-dazzle effect is achieved. However, when AG anti-glare/anti-light scattering surfaces are used in transparent media such as glass based on this treatment, flash points are generally generated, mainly because AG anti-glare/anti-light scattering treatments cause the glass surface to become irregular diffuse reflection, and when applied to transparent media between a user and an object, they distort the optical path of transmitted light, resulting in flash points.

In a paper-like screen design, a flash point (flash) phenomenon, generally described as a particle or a sparkling effect, is generated by AG surface treatment of transmitted Light of an LCD (Liquid Crystal Display ) or an OLED (Organic Light-Emitting Diode) or the like, and the flash point (flash) is generated by optical distortion of Light in random Light refraction and uneven illumination caused by a Pixel direction in a display screen/display application scene such as a paper-like screen, and is specifically shown in fig. 2 (each color block in a Pixel Array represents one Pixel, and the Pixel direction can be understood as a direction in which a viewer views the Pixel). Referring to fig. 3, a display sample is provided in which the display screen produces flash points in the display of information that can affect the visual effect of the user viewing the information.

Based on the above, the application provides a display device and an electronic device, which are used for solving the technical problems existing in the related art, reducing the flash point in the information display of the display device/the display screen, and achieving the anti-flash point effect.

Referring to fig. 4, the display device provided in the embodiment of the present application at least includes a display module 10 and a transmission processing module 20 connected to the display module 10.

Alternatively, the diffraction grating structure of the diffractor 201 is specifically a two-dimensional diffraction grating structure.

The second display light includes a third display light, and the third display light has a first included angle compared with the corresponding first display light (i.e., the incident light of the third display light corresponding to the diffractor). In addition, the second display light may further include a fourth display light, where the fourth display light is not deflected compared to the corresponding first display light (i.e., the fourth display light is incident on the diffractor) and there is no included angle between the fourth display light and the corresponding first display light.

Specifically, when the diffracting body 201 diffracts the first display light beam output when the display module 10 displays information, based on the diffraction grating structure, such as a two-dimensional diffraction grating structure, a part of the first display light beam directly emits through the diffracting body without any deflection, the output light beam generated after the part of the first display light beam directly outputs through the diffracting body is the fourth display light beam, and another part of the first display light beam deflects through the diffracting body, and the light beam output after the deflection is the third display light beam. The transmission processing module 20 diffracts the first display light through the diffracting body 201, so as to scatter the first display light.

To sum up, in this embodiment of the application, through add the transmission processing module in display device, and set up the diffraction body of diffraction grating structure in the transmission processing module, make the diffraction output of the diffraction grating structure of diffraction body in the accessible transmission processing module to the first display light of display module output in the display device, through carrying out the diffraction to the first display light of display module output, can reach the effect of scattering first display light, reduce/avoided the optical distortion of light in the random light refraction plus the inhomogeneous phenomenon of illumination that the pixel orientation led to, thereby in the display screen application scenario such as class paper screen, flash point in the display screen information display can effectively be reduced, reach the anti-flash point effect.

Optionally, the plurality of building blocks comprises a same type of building block, wherein there is a height difference between at least a portion of different locations within each building block of the same type of building block.

Preferably, each structural unit in the same class of structural units is an arch structure. The arch width and arch height of each arch structure unit are the same (the height of the highest point of the arch is the same and the height of the non-highest point at the corresponding position is the same). Individual structural elements of the same type are combined in an array fashion into a two-dimensional diffraction grating structure, wherein the array may be, but is not limited to, an array of 3*3, 4*4 or 5*5, see fig. 5, providing a schematic cross-sectional view of a two-dimensional diffraction grating structure of a 5*5 array.

Alternatively, the first type of structural unit and the second type of structural unit are also arch structural units, the arch heights of the two types of arch structural units are different, and the arch widths can be the same or different. The two types of arch-shaped structural units are combined into a two-dimensional diffraction grating structure in an array mode. Alternatively, the two types of arch-shaped structural units are alternately arranged in the array, and the size of the array is not limited as well and can be determined according to actual requirements. In this embodiment, each type of structural unit also has a function of scattering light based on at least partially different positions inside the structural unit corresponding to different curvatures.
