Description
Technical Field
The present invention relates to the field of liquid crystal display technologies, and in particular, to a display device.
Background
With the continuous progress of the liquid crystal display technology, the viewing angle of the display has been widened from about 120 ° to over 160 °, and people want to effectively protect business confidentiality and personal privacy while enjoying visual experience brought by a large viewing angle, so as to avoid business loss or embarrassment caused by the leakage of screen information. Although the current display device gradually develops towards a wide viewing angle, no matter the application of the mobile terminal of the mobile phone, the desktop display or the notebook computer, besides the requirement of the wide viewing angle, in many occasions, the display device is required to have a function of switching between the wide viewing angle and the narrow viewing angle. At present, there are several ways to switch between a wide viewing angle and a narrow viewing angle of a liquid crystal display device.
The first method is realized by attaching a shutter film on a display screen. When peep-proof is needed, the view angle can be reduced by using the shutter shielding film to shield the screen. However, this method requires additional preparation of the louver films, which causes great inconvenience to the user, and one louver film can achieve only one viewing angle. Once the louver shielding film is attached, the visual angle is fixed, only the narrow visual angle mode can be realized, and the wide visual angle function can not be displayed.
The second is to arrange a dual light source backlight system in the lcd device for adjusting the viewing angle of the lcd device, the dual light source backlight system is composed of two stacked light guide plates combined with an inverse prism sheet, the top light guide plate (LGP-T) combined with the inverse prism sheet changes the direction of the light so that the light is limited in a relatively narrow angular range, thereby realizing the narrow viewing angle of the lcd device, while the bottom light guide plate (LGP-B) combined with the inverse prism sheet functions to realize the wide viewing angle of the lcd device. However, such a dual-light source backlight system increases the thickness and cost of the liquid crystal display device, and is not suitable for the trend of thinning the liquid crystal display device.
The third is to divide the driving electrodes on the panel of the liquid crystal display device into two types, one is the wide viewing angle display driving electrode, and the other is the viewing angle control electrode, when a proper voltage is applied to the viewing angle control electrode, the liquid crystal display device can generate proper light leakage, and further realize the switching between the wide viewing angle and the narrow viewing angle. However, the liquid crystal display device needs to be provided with two electrodes, namely a wide viewing angle display driving electrode and a viewing angle control electrode, so that the aperture ratio of the liquid crystal display device is reduced, the panel brightness of the liquid crystal display device is reduced, and the manufacturing process is more complicated.
And fourthly, arranging a double liquid crystal cell in the liquid crystal display device for adjusting the visual angle of the liquid crystal display device, wherein the double liquid crystal cell is composed of a top liquid crystal layer and a bottom liquid crystal layer which are vertically aligned, and switching between a wide visual angle and a narrow visual angle is realized by controlling the voltage applied to the two liquid crystal cells. However, two liquid crystal layers need to be disposed on the device, so that the cost of the liquid crystal display device is increased, the thickness and the power consumption are increased, and the development trend of the liquid crystal display device to be light and thin is not met.
In summary, the technology capable of switching between wide and narrow viewing angles is generally applicable to Liquid Crystal Displays (LCDs), and is not applicable to self-emitting display devices such as AMOLEDs and Micro LEDs. Therefore, there is a need to provide a new technical solution to overcome the above technical problems in the prior art.

In the present embodiment, the first display panel 10 and the second display panel 20 are self-emitting display panels, such as an organic light emitting diode display panel (OLED), but not limited thereto. The first display panel 10 includes a first substrate 110, a first light emitting layer 120, and a first light shielding layer 130, the first light emitting layer 120 is disposed on the first substrate 110, and the first light shielding layer 130 is stacked on the first light emitting layer 120. Specifically, the first light-emitting layer 120 includes a plurality of first light-emitting elements (not numbered) spaced apart from each other, and the first light-shielding layer 130 includes a plurality of first light-shielding portions (not numbered) spaced apart from each other, where the first light-shielding portions have the same width as the first light-emitting elements in the present embodiment, and each first light-shielding portion is disposed on each first light-emitting element in a stacked manner. The width of the first shading part is a, the width between two adjacent first shading parts is b, and the sum of a and b is the width of one sub-pixel.
The second display panel 20 includes a second substrate 210, a second light emitting layer 220 and a second light shielding layer 230, the second light shielding layer 230 is disposed on the second substrate 210 near the first substrate 110, and the second light shielding layer 230 is disposed opposite to the first light shielding layer 130. The second light emitting layer 220 is disposed on the second substrate 210 at a side far from the second light shielding layer 230, and the second light shielding layer 230 and the second light emitting layer 220 are disposed alternately. Preferably, an adhesive layer 30 may be disposed between the first display panel 10 and the second display panel 20, the first light shielding layer 130 and the second light shielding layer 230 are respectively adhered to the adhesive layer 30 to adhere the first display panel 10 and the second display panel 20 together, and the width a of the first light shielding layer 130 is equal to the length of the second light shielding layer 230. The adhesive layer 30 may be provided as a frame sticker, but is not limited thereto. In other embodiments, a full-paste approach may also be employed. After the first display panel 10 and the second display panel 20 are bonded together, the second light shielding layer 230 is located below the first light shielding layer 130, so that the projection of the second light emitting layer 220 on the first substrate 110 falls between two adjacent first light shielding portions, and light emitted by the second light emitting layer 220 can exit through the gap between the first light shielding layer 130 and the second light shielding layer 230. Specifically, the second light shielding layer 230 includes a plurality of second light shielding portions (not numbered) spaced apart from each other, and the second light emitting layer 220 includes a plurality of second light emitting elements (not numbered) spaced apart from each other, and a projection of the second light emitting element on the second substrate 210 is located between two adjacent second light shielding portions.
In this embodiment, in order to improve the light utilization efficiency, a reflective surface (not shown) is disposed between the first light-shielding portion and the first light-emitting element, and the light emitted from the first light-emitting element to the first light-shielding portion is reflected by the reflective surface and reused, so as to prevent the light emitted from the first light-emitting element to the first light-shielding portion from being directly absorbed by the first light-shielding portion and being unusable. Similarly, the bottom of the second light-shielding layer 230 near the second substrate 210 is provided with a reflective surface, so that the light emitted from the second light-emitting device to the second light-shielding layer 230 is reflected by the reflective surface and reused.
As shown in fig. 1, the width of the second light emitting element is c, and the thickness of the second display panel 20 is d. In order to prevent the second display panel 20 from light leakage and color mixing, that is, the light emitted from the second light emitting element in the second light shielding layer 230 cannot be emitted from the opening region of the adjacent pixel, i.e., a is not less than d. Specifically, as shown by the light ray a in fig. 1, when light enters the optically thinner medium from the optically denser medium, a total reflection phenomenon occurs when the incident angle θ increases to a certain degree. In this embodiment, the first substrate 110 and the second substrate 210 are both glass substrates, and the refractive index n thereof is 1.4. When the incident angle of the light ray a is greater than the critical angle of 45.6 °, total reflection occurs, that is, when the incident angle of the light ray a is greater than 45.6 °, the light ray cannot exit into the first display panel 10, that is, the light leakage phenomenon does not occur.
In addition, c ≦ 0.4d is required for the display device 100 to achieve a narrow viewing angle in the range of ± 30 °. From the law of refraction sin θ1/sinθ2When the refractive index n1 of the substrate is 1.4 and the refractive index n2 of the air is 1.0, the angle θ of the light emitted from the second display panel 20 is determined as n2/n12Not more than 30 DEG, theta1Less than or equal to 21 DEG, and tan theta1C/d, tan21 DEG ≦ c/d, i.e. c ≦ 0.4 d.

The second display panel 20 is a Liquid Crystal Display (LCD) panel, and the structure of the second display panel 20 is similar to that of the conventional LCD panel, and is not described herein again. In this embodiment, in order to reuse the light emitted to the second light shielding layer 230 in the backlight, a reflective surface (not shown) is disposed on a side of the second light shielding layer 230 facing the backlight, so that the light emitted to the second light shielding layer 230 is reflected by the reflective surface and reused, thereby improving the utilization rate of the light. Meanwhile, in order to make the light emitted from the first light emitting element 120 of the self-luminous first display panel 10 exit toward the outside of the display panel, a reflective surface is disposed on the surface of the first light emitting element 120 contacting with the first light shielding layer 130, and the light emitted from the first light emitting element 120 toward the reflective surface is reflected by the reflective surface and exits the display device 100, so as to improve the utilization rate of the light.
In the display device 100 of the present invention, the first display panel 10 and the second display panel 20 are provided on the display device 100, and the first display panel 10 is stacked on the second display panel 20.
