The main board 2 is electrically connected with the display screen 3. The main board 2 is used for controlling the display content of the display screen 3. It is understood that the motherboard 2 is provided with electronic devices and circuits such as a processor and a memory. The main board 2 is used for controlling the display content of the display screen 3 according to an operation instruction of a user or a pre-stored instruction and the like. Of course, the electronic device 100 also includes a power source. For example, the power source is a battery 4 provided in the housing space 10. The battery 4 may be one of a lithium ion battery, a nickel cadmium battery, a nickel hydrogen battery, and the like. The battery 4 is electrically connected with the mainboard 2 and supplies power to the mainboard 2. The battery 4 is electrically connected with the display screen 3 and supplies power to the display screen 3.
For convenience of description, a coordinate system as shown in fig. 2 is established, wherein the X-axis direction may be understood as a length direction of the electronic apparatus 100; the Y-axis direction may be understood as the width direction of the electronic device 100; the Z-axis direction may be understood as a thickness direction of the electronic apparatus 100. The length direction, width direction, and thickness direction of the display screen 3 correspond to the length direction, width direction, and thickness direction of the electronic apparatus 100, respectively.
As shown in fig. 3, fig. 3 is a schematic cross-sectional view of a display screen 3 according to an embodiment of the present disclosure. The display screen 3 comprises a light emitting substrate 30 and a cover plate assembly 31. The length direction, the width direction, and the thickness direction of the light-emitting substrate 30 correspond to the length direction, the width direction, and the thickness direction of the display panel 3, respectively. The cover assembly 31 has a length direction, a width direction, and a thickness direction corresponding to the length direction, the width direction, and the thickness direction of the display screen 3, respectively.
When the display screen 3 is an LCD display screen 3, the light-emitting substrate 30 may be a backlight module. When the display screen 3 is an LED or OLED display screen 3, the light emitting substrate 30 includes a plurality of light emitting diodes. In the embodiment of the present application, the OLED display panel 3 is taken as an example without being particularly described. In one embodiment, as shown in fig. 4, the light-emitting substrate 30 includes a cathode layer 301, a light-emitting layer 302, an anode layer 303, and a substrate 304. The cathode layer 301, the light emitting layer 302, the anode layer 303, and the substrate 304 are sequentially stacked in the thickness direction of the display panel 3; alternatively, the anode layer 303, the light-emitting layer 302, the cathode layer 301, and the substrate 304 are stacked in this order in the thickness direction of the display panel 3. The substrate 304 may be plastic, glass, etc. Anode layer 303 includes a plurality of anode leads. The anode lead is electrically connected with the anode of the external driving circuit. The anode lead may be made of a non-transparent conductive material (e.g., metal) or a transparent conductive material (e.g., ITO). The cathode layer 301 includes a plurality of cathode leads. The cathode lead is electrically connected with the negative electrode of the external driving circuit. The cathode may be made of a non-transparent conductive material (e.g., metal) or a transparent conductive material (e.g., ITO). The light emitting layer 302 generates light under the influence of an electric field between the anode layer 303 and the cathode layer 301. The light-emitting substrate 30 may be driven by a passive driving method or an active driving method.
The cover member 31 covers the light emitting side of the light emitting substrate 30. In other words, the light emitting substrate 30 emits light toward the side of the cover member 31. In one embodiment, as shown in fig. 4, the cover plate assembly 31, the cathode layer 301, the light emitting layer 302, the anode layer 303 and the substrate 304 are sequentially stacked along the thickness direction of the display screen 3. In another embodiment, as shown in fig. 5, the cover plate assembly 31, the anode layer 303, the light emitting layer 302, the cathode layer 301 and the substrate 304 are sequentially stacked along the thickness direction of the display screen 3. The light-emitting surface 310 of the cover assembly 31 faces a side away from the light-emitting substrate 30. It can be understood that the light generated by the light-emitting layer 302 of the light-emitting substrate 30 is incident into the cover assembly 31 and is emitted to the outside of the display 3 through the light-emitting surface 310 of the cover assembly 31.
As shown in fig. 6, fig. 6 is a schematic structural diagram of a cover plate assembly 31 according to an embodiment of the present disclosure. The cover plate assembly 31 includes a transparent substrate 311 and a plurality of reflective members 312.
Referring to fig. 4 to 6, the transparent substrate 311 may be one of a glass substrate and a plastic substrate. In the embodiments of the present application, a glass substrate is taken as an example. The light-transmitting substrate 311 is used to transmit light. Specifically, when the light emitted from the light-emitting substrate 30 is emitted to the transparent substrate 311, the light is emitted linearly through the light-emitting surface 310 or is further refracted at the light-emitting surface 310. The light-transmitting substrate 311 includes a first light-transmitting surface 311a and a second light-transmitting surface 311b opposite to each other, and a peripheral side surface 311c connected between the first light-transmitting surface 311a and the second light-transmitting surface 311 b. The first and second light-transmitting surfaces 311a and 311b may be flat (e.g., rectangular, square, irregular, etc.) or curved. The peripheral side surface 311c may be a flat surface or an arc surface. One of the first transparent surface 311a and the second transparent surface 311b far from the light-emitting substrate 30 can be understood as the light-emitting surface 310 of the cover assembly 31.
The reflector 312 may be a metallic reflector 312 (e.g., silver, copper, gold, etc.), a specular reflector 312, or the like. The number of the reflective members 312 is not particularly limited in the present application. The number of reflectors 312 may be two, four, seven or more, etc. The reflective member 312 is disposed on the transparent substrate 311. In other words, the reflective member 312 is fixed on the transparent substrate 311. The reflective member 312 may be directly formed on the transparent substrate 311, or may be connected with the transparent substrate 311 as a whole. For example, the reflective member 312 may be directly formed on the transparent substrate 311 by printing, evaporation, etching, or the like; alternatively, the reflective member 312 is adhered to the transparent substrate 311. Each of the reflecting members 312 includes at least one reflecting surface 312 a. The number of the reflecting surfaces 312a included in each reflecting member 312 is not particularly limited. Each reflector 312 may include a reflective surface 312 a; or each reflective element 312 includes a plurality of reflective surfaces 312a, or a portion of the reflective elements 312 includes one reflective surface 312a and another portion of the reflective elements 312 includes a plurality of reflective surfaces 312 a.
Referring to fig. 4 to 6, the reflection surface 312a is inclined with respect to the light emitting surface 310. The reflection surface 312a is used for reflecting the light and emitting the light obliquely with respect to the light emitting surface 310. Specifically, when the light emitted from the light-emitting substrate 30 is emitted to the reflective element 312, the light is reflected by the reflective surface 312a and is emitted out through the light-emitting surface 310 linearly or is further refracted at the light-emitting surface 310. Since the reflection surface 312a is inclined with respect to the light emitting surface 310, the light is emitted obliquely with respect to the light emitting surface 310. Therefore, when the display screen 3 is directly viewed, the reflected light is not or less incident on the eyes of the user, so that the user can obtain normal display contents of the display screen 3; when the display screen 3 is obliquely viewed, the reflected light is totally or largely emitted into the eyes of the viewer, so that the viewer cannot obtain the normal display content of the display screen 3.
The reflection surface 312a may be a plane inclined with respect to the light emitting surface 310 or an arc surface inclined with respect to the light emitting surface 310. When the reflection surface 312a is a curved surface inclined with respect to the light exit surface 310, for example: the reflecting surface 312a is a convex arc surface, and at this time, the reflecting surface 312a can collect the reflected light, so that the light obliquely emitted from the light emitting surface 310 is more concentrated, the light intensity is stronger, and the effect of privacy protection can be improved. When the reflection surface 312a is a concave arc surface, the reflection surface 312a can receive more light emitted from the light-emitting substrate 30, so that more reflected light obliquely emitted from the light-emitting surface 310 is emitted, the intensity of the light is enhanced, and the effect of privacy protection is improved.
The cover plate assembly 31 provided by the present application includes a transparent substrate 311 and a plurality of reflectors 312 disposed on the transparent substrate 311, wherein the transparent substrate 311 is used for transmitting light, and the reflectors 312 are used for reflecting light and emitting the light obliquely relative to the light emitting surface 310 of the cover plate assembly 31, so when the cover plate assembly 31 is applied to the display screen 3, if the display screen 3 is directly viewed, the light directly transmitted by the transparent substrate 311 is seen, that is, the normal display content of the display screen 3 is seen; when the display screen 3 is obliquely viewed, a halo formed by the light transmitted by the transparent substrate 311 and the light reflected by the reflector 312 is observed, that is, the display content of the display screen 3 cannot be clearly seen by oblique viewing, so that the privacy of the user is protected by the cover plate assembly 31. The display screen 3 and the electronic device 100 provided by the application have the cover plate assembly 31, so that the privacy of users can be effectively protected.
In one embodiment, as shown in FIG. 7, each reflector 312 includes at least one first reflective surface 312b and at least one second reflective surface 312 c. In other words, each of the reflection members 312 includes a plurality of reflection surfaces 312 a. The number of the first reflecting surfaces 312b may be one or more. The number of the second reflection surfaces 312c may be one or more. The number of the first reflecting surfaces 312b and the number of the second reflecting surfaces 312c may be the same or different. For example: each reflecting member 312 includes a first reflecting surface 312b and a second reflecting surface 312 c; alternatively, each of the reflective members 312 includes a first reflective surface 312b and a plurality of second reflective surfaces 312 c; still alternatively, each of the reflective members 312 includes a plurality of first reflective surfaces 312b and a second reflective surface 312 c; still alternatively, each of the reflection members 312 includes a plurality of first reflection surfaces 312b and a plurality of second reflection surfaces 312 c. In this embodiment, each of the reflective members 312 includes a first reflective surface 312b and a second reflective surface 312 c. Optionally, the inclination angle α between the first reflection surface 312b and the light emitting surface 310 is 30 ° to 70 °. The inclination angle β between the second reflecting surface 312c and the light emitting surface 310 is 30 ° to 70 °.
The orientation of the first reflecting surface 312b is different from the orientation of the second reflecting surface 312 c. In one embodiment, the first reflective surface 312b faces generally to the left of the display screen 3.

In this embodiment, the orthographic projection of the reflector 312 on the light-emitting substrate 30 is located in the gaps between the red sub-pixel and the first green sub-pixel and between the blue sub-pixel and the second green sub-pixel. Similarly, the light emitted by the sub-pixels 3201 can be shielded or prevented by positioning the orthogonal projection of the reflector 312 on the light-emitting substrate 30 in the gap between the sub-pixels 3201, so that the light emitted by the sub-pixels 3201 can be emitted through the light-emitting surface 310 to realize the normal display of the display screen 3.
