In some implementations, the cover plate11may be disposed in front of the display screen12. In the present embodiment, “front” refers to the direction in which a side of the display screen12for displaying information is facing. “back” refers to a direction opposite to “front”.

The cover plate11may have an exposure region11that exposes information displayed on the display screen12, and a non-exposure region12for protection from external viewing. The non-exposure region12may include a light shielding layer, e.g., a black cushion layer, so that the interior of the terminal100may be protected from external viewing. In some embodiments, the light shielding layer is an ink layer.

The display screen12may be a liquid crystal display (LCD) for displaying an electronic file on a screen, and the display screen12may display information such as an image, a video, or text. The display screen12may include a front surface for displaying information, and a rear surface opposite to the front surface.

In some embodiments, as shown inFIG.2, the display screen12may include a display region121for displaying information and a non-display region122that is not used to display information. The display region121may serve as a main display region of the display screen12, and the main display region is configured to display most of the information. The non-display region122may be provided outside the display region121. The non-display region122may be used to provide a region in which an integrated circuit (IC) for controlling information display of the display screen12is disposed. The non-exposure region12of the cover plate11may be disposed in front of the non-display region122of the display screen12and prevent the non-display region122of the display screen12from being externally visible.

In some embodiments, referring toFIG.3,FIG.3is a front view of the terminal100. As shown inFIG.3, the display screen12may be a bezel-free display screen. That is, the display screen12may include the display region121, but not include the non-display region122, to achieve a larger screen for displaying.

Referring toFIG.4,FIG.4is a schematic block view of a display screen12according to an embodiment of the present disclosure. As shown inFIG.4, the display screen12may include a touch panel1201, an optical adhesive layer1202disposed below the touch panel1201, a light guide plate1211disposed below the optical adhesive layer1202, and a light emitting member1213for emitting light. The light passes through the light guide plate1211and the optical adhesive layer1202to the touch panel1201. The light emitting member1213may be a light emitting diode (LED). The light-emitting member1213may be used to provide a light source for a display screen.

The light guide plate1211may be configured to convert a line light source emitted by the light emitting member into a surface light source. The light guide plate1211may include a light guide plate layer and a diffusion layer disposed on an upper surface of the light guide plate layer. The diffusion layer is used to cause diffuse reflection of light emitted by the light emitting member.

The optical adhesive layer1202is formed of an optical adhesive, which may be a special adhesive for bonding the transparent optical element. It has colorless transparency, light transmittance of 90% or more, good cementitious strength, curing at room temperature or medium temperature, low curing shrinkage, and the like. The optical adhesive layer1202is used to adhere the touch panel1201to an upper polarizer via the optical adhesive.

Further, the optical adhesive layer1202may further include diffusion particles for atomizing light transmitted through the light guide plate1211. In an implementation of the present disclosure, by doping the diffusion particles in the optical adhesive layer1202, the light transmitted through the light guide plate1211may be atomized by the diffusion particles in the optical adhesive layer1202, so that the light is diffusely reflected, thereby softening the display effect of the display screen and avoiding glare of the display screen.

in some implementations, the diffusion layer of the light guide plate1211is a diffusion coating layer or a bump structure layer for diffusing light emitted by the light emitting member. By adding a diffusion coating layer onto the upper surface of the light guide plate layer in the light guide plate1211, or by adding a bump, that is, a bump structure layer, to the upper surface of the light guide plate layer, light is diffusely reflected when transmitted through the light guide plate1211, so that the emitted light becomes softened, thereby reducing irritation to the human eye.

In some implementations, the display screen12may further include a polarizer through which a polarizing effect is generated to control the illumination intensity of the display screen. The polarizer is disposed between the optical adhesive layer1202and the light guide plate1211. The polarizer may include an upper polarizer1203disposed between the optical adhesive layer1202and the light guide plate1211and a lower polarizer1206disposed between the upper polarizer1203and the light guide plate1211.

In an implementation of the present disclosure, the polarizer has a matte surface. Specifically, by chemical etching or spraying, the surface of the polarizer may be changed to a matte surface (an uneven surface with particles), thereby changing the roughness of the surface of the polarizer, so that the surface of the polarizer has a matte effect, thereby achieving a diffuse reflection effect of light.

In some implementations, the display screen12may further include a plurality of diffusion film layers disposed between the polarizer and the light guide plate1211. Specifically, the plurality of diffusion film layers may include a first diffusion film1210, a second diffusion film1209, a third diffusion film1208, a fourth diffusion film1207, and/or the like. The number of diffusion film layers is not limited herein. By providing the plurality of diffusion film layers, the light transmitted through the light guide plate1211may be further atomized to diffusely reflect the light, so as to make the visual effect of the display screen become soft.

In some implementations, the display screen12may further include a light shielding tape1217disposed between the polarizer and the diffuser film layers, that is, the diffusion film layers. The light shielding tape1217may be configured to shield the light around the backlight, so that the light in the visual area of the display screen is uniform and no light leaks.

In some implementations, the display screen12may further include a color filter1204disposed between the upper polarizer1203and the lower polarizer1206and a thin film transistor1205disposed between the color filter1204and the lower polarizer1206. The color filter1204and the thin film transistor1205are configured for content display of the display screen.

In some implementations, the touch panel1201may include a glass reflection surface, which may be a matte surface. Specifically, by chemical etching or spraying, the surface of the glass reflection surface may be changed to a matte surface (an uneven surface with particles), thereby changing the roughness of the glass reflection surface, so that the surface of the glass reflection surface has a matte effect, thereby achieving a diffuse reflection effect of light.

In some implementations, the display screen12may further include a reflection sheet1212disposed below the light guide plate1211. The reflection sheet1212may be configured to reflect light from the bottom of the light guide plate to the visible region for reuse.

In some implementations, the display screen12may further include an adhesive frame1216for holding the light guide plate1211and the reflection sheet1212, an iron frame1215for protecting the display screen12, and a peripheral wrapping tape1214disposed around the display screen12.

The adhesive frame1216may be configured to fix the backlight film material, the light guide plate1211, and the reflection sheet1212, and carry the display screen12. The iron frame1215may be configured to protect the backlight and the display screen. The peripheral wrapping tape1214may be configured to shield the periphery of the display screen, prevent light leakage of the display screen, and shield the electromagnetic interference.

The display screen12according to an embodiment of the present disclosure may include a touch panel1201, an optical adhesive layer1202disposed below the touch panel1201, a light guide plate1211disposed below the optical adhesive layer1202, and a light emitting member1213for emitting light. The light passes through the light guide plate1211and the optical adhesive layer1202to the touch panel1201. The light guide plate1211may include a light guide plate layer and a diffusion layer disposed on an upper surface of the light guide plate layer. The diffusion layer is used to cause diffuse reflection of light emitted by the light emitting member. The optical adhesive layer1202may further include diffusion particles for atomizing light transmitted through the light guide plate1211. The light emitted by the light emitting member1213is diffusely reflected by the diffusion layer of the light guide plate1211and the diffusion particles of the optical adhesive layer1202, thereby avoiding glare caused by high-brightness light, thereby reducing the stimulation of the high-brightness display screen to the human eye.
