In other cases, known methods, devices, realizations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0046] Embodiment 1

[0047] A display panel 100 is provided in the first embodiment of the present application. The display panel 100 may be a liquid crystal display panel 100 (LCD) or an organic light emitting diode (OLED).

[0048] See also Figure 1 and Figure 2 As shown, the display panel 100 includes a base substrate 110, a color resist layer, a black matrix 130 (BM) and a reflective layer.

[0049] The base substrate 110 may be a glass substrate, but is not limited thereto, and may also be a substrate made of other materials, such as PI material.

[0050] See also Figure 1 As shown, the color resist layer includes a plurality of color resist units 121 arranged in an array, and the plurality of color resist units 121 are sequentially spaced in the row direction X and the column direction Y. Each color resist unit 121 includes a plurality of color resists 1210, and the luminous colors of adjacent color resists 1210 are different. A black matrix 130 is provided between adjacent color resists 1210 to isolate the light between the adjacent color resists 1210 to prevent the visual effect from being affected.

[0051] For example, Figure 1 As shown, each color resist unit 121 includes red color resist, green color resist and blue color resist. The color resists 1210 in the same column direction Y emit the same color, and the red color resist, green color resist and blue color resist in the same row direction X are arranged alternately.

[0052] It is understandable that the color resist layer can be designed in different positions according to the type of display panel 100. For example, when the display panel 100 is a liquid crystal display panel 100, the color resist layer can be arranged on the opposite substrate or on the array substrate side. When the display panel 100 is an organic light emitting diode, the color resist layer can be located on the upper side of the encapsulation layer, and the color resist 1210 in the color resist layer corresponds to the light emitting part of the organic light emitting diode respectively, so as to increase the color of the light and improve the visual effect.

[0053] In the examples of this application, see Figure 2 As shown, the reflective layer is disposed on the base substrate 110, and the reflective layer includes a plurality of transparent reflective units 141. At least a portion of the reflective units 141 is covered by the black matrix 130, and the reflective units 141 are spaced apart from the color resist 1210 to avoid the reflective units 141 occupying too many pixel openings, thereby improving the pixel opening ratio.

[0054] In the examples of this application, see Figure 2 and Figure 3 As shown, a reflector 1420 is provided on the surface of the reflective unit 141. The reflector 1420 can be used to reflect light. The light reflected by the reflector 1420 can mix with the light emitted by the color resist 1210 to interfere with information acquisition, thereby realizing an anti-peeping mode.

[0055] It should be noted that the reflective unit 141 is in a transparent state so that the light can be reflected at the reflective member 1420 to mix with the light emitted by the color resist 1210 to interfere with information acquisition, thereby realizing the anti-peeping mode.

[0056] By using the reflective unit 141 and the reflective member 1420 in the solution of the present application to be embedded in the black matrix 130, it is possible to achieve anti-peeping, and also reduce the design positions of the reflective unit 141 and the reflective member 1420, thereby reducing the thickness of the display panel 100 and the cost of the display panel 100. In other words, the solution can achieve anti-peeping while also reducing the thickness of the display panel 100 and the manufacturing cost of the entire display panel 100.

[0057] In the examples of this application, see Figure 1As shown, the reflective unit 141 is disposed between two adjacent color resist units 121 in the column direction Y, that is, the reflective unit 141 is located between two rows of color resist units 121 to avoid the reflective unit 141 occupying the gap between adjacent color resists 1210, thereby ensuring the pixel aperture ratio while preventing peeping.

[0058] It is worth mentioning that the reflector 1420 can reflect external light. After being reflected by the reflector 1420, the external light mixes with the light emitted by the color resist 1210, interfering with information acquisition, thereby realizing the anti-peeping function. The reflector 1420 can also reflect its own light. Depending on the type of the display panel 100, the reflector 1420 reflects different light. For example, when the display panel 100 is a liquid crystal display panel 100, the reflector 1420 reflects the light emitted by the backlight module; when the display panel 100 is an organic light emitting diode, the reflector 1420 reflects the light emitted by the light emitting portion.

[0059] In the embodiment of the present application, the reflective element 1420 is capable of reflecting external light, and mixing the reflected external light with the light emitted by the color resist 1210. When the display panel 100 is viewed at a certain angle, the display panel 100 generates reflections, which interfere with information acquisition, thereby realizing an anti-peeping mode.

[0060] It should be noted that the reflector 1420 can be disposed on the inner surface of the reflective unit 141 or on the outer surface of the reflector 1420 , as long as it can reflect external light.

[0061] In the examples of this application, see Figure 2 and Figure 3 As shown, the black matrix 130 completely covers the reflective unit 141 and the reflective element 1420. The reflective element 1420 is disposed on the outer surface of the reflective unit 141. Compared with the solution in which the reflective element 1420 is disposed on the inner surface of the reflective unit 141, the design thereof is simpler, and there is no need to dispose a layer of reflective element 1420 inside the reflective unit 141, and only a layer of reflective element 1420 needs to be designed on the outer surface of the reflective unit 141.

[0062] It can be understood that the black matrix 130 completely covers the reflective unit 141 and the reflective element 1420 , which is equivalent to providing a plurality of groove structures on the black matrix 130 , and the reflective unit 141 provided with the reflective element 1420 is embedded in the groove structure.

[0063] By using the black matrix 130 to cover the reflective unit 141 and the reflective member 1420 , the anti-peeping function can be achieved while reducing the thickness and weight of the entire display panel 100 , thereby reducing the cost of the entire display panel 100 .

[0064] It should be noted that the outer wall surface of the reflection unit 141 can be a curved surface or a flat surface, as long as it can reflect part of the external light out of the reflection unit 141 to achieve anti-peeping.

[0065] In the examples of this application, see Figure 3 As shown, the outer wall surface of the reflective unit 141 is a curved surface. The reflective member 1420 is attached to the outer wall surface of the reflective unit 141. External light enters the reflective unit 141 from the side of the substrate 110. A part of the external light is reflected at the reflective member 1420. A part of the external light reflected by the reflective member 1420 remains in the reflective unit 141 and is absorbed by the black matrix 130. Another part of the reflected light is emitted from the inside of the reflective unit 141. The emitted light is mixed with the light emitted by the adjacent color resist 1210 to form a reflection, thereby interfering with information reading and realizing the anti-peeping function. Another part of the external light is absorbed by the black matrix 130.

[0066] It is understandable that the curved surface can ensure that the external light within a certain angle range will not be emitted from the reflecting unit 141 when it enters the reflecting unit 141, but will be absorbed by the black matrix 130. The external light at other angles can pass through the reflecting member 1420 and be emitted from the reflecting unit 141, and be mixed with the light emitted by the adjacent color resist 1210, thereby realizing the anti-peeping function.

[0067] In addition, the reflective unit 141 may be a spherical segment structure or other curved surface structures, as long as the light can be reflected from the reflective unit 141 when it hits the reflective element 1420 .

[0068] In the examples of this application, see Figure 3 and Figure 4 As shown, the reflective unit 141 is a spherical structure, and the curved surface is an arc surface. The reflective unit 141 may include at least one hemispherical reflective body 1410, at least one hemispherical reflective body 1410 is embedded in the black matrix 130, and the reflective member 1420 is provided on the outer wall surface of each reflective body 1410, one end of the reflective member 1420 is connected to the substrate 110, and the other end is extended along the outer wall surface of the reflective body 1410. The reflective member 1420 embedded in the black matrix 130 is used to reflect the external light, wherein the coverage area of ​​the reflective member 1420 is less than half of the surface area of ​​the reflective body 1410, so as to ensure that the external light will not be emitted from the reflective body 1410 under the normal viewing angle, so as to avoid the external light reflection affecting the display effect under the normal viewing angle, and ensure the light brightness under the normal viewing angle.

[0069] It should be noted that the longitudinal section of the reflecting unit 141 can be smaller than a semicircle or larger than a semicircle, that is, the size of the position where the reflecting unit 141 is connected to the base substrate 110 is smaller than the diameter of the spherical structure, as long as the reflecting unit 141 can be ejected from the connection between the reflecting unit 141 and the base substrate 110.

[0070] In addition, the position of the reflector 1420 can also be changed according to the design shape of the reflector unit 141 , as long as the reflector 1420 can ensure that part of the external light is emitted from the connection between the reflector unit and the base substrate 110 , and the emitted light is mixed with the adjacent color resist 1210 .

[0071] It is worth mentioning that the side facing the display panel 100 vertically is a normal viewing angle. When external light enters the reflective body 1410 at a normal viewing angle and a certain angle, the light will be reflected at this reflective component 1420. The reflected light is absorbed by the black matrix 130, and cannot be mixed with the light emitted from the reflective body 1410 and the adjacent color color block 1210, thereby ensuring information reading at a normal viewing angle and a certain angle. External light at another angle enters the reflective body 1410, and the light at this angle will be reflected at this reflective component 1420, and the light emitted from the reflective body 1410 and the adjacent color color block 1210 will be mixed, interfering with information reading, thereby achieving anti-peeping.

[0072] In the embodiment of the present application, in order to prevent external light from passing through the reflector 1420 and emitting out of the reflective body 1410 under a normal viewing angle, the arc length corresponding to the reflector 1420 in the cross section in the thickness direction of the base substrate 110 is less than πr / 3, where r is the radius of the reflective body 1410.

[0073] In the examples of this application, see Figure 2 and Figure 3 As shown, the reflection unit 141 includes two hemispherical reflection bodies 1410, and the two hemispherical reflection bodies 1410 are arranged at an interval with each other. The two reflection bodies 1410 can enhance the amount of external light reflection, enhance the interference effect, and improve the anti-peeping effect.

[0074] It can be understood that through the two reflective bodies 1410, external light at a certain angle will be reflected out of the reflective body 1410 through the two reflective parts 1420, and mixed with the light emitted by the adjacent color block 1210. The amount of external light participating in the mixing is increased, the anti-peeping interference effect is better, and the anti-peeping effect is thereby enhanced.

[0075] In addition, the reflective elements 1420 on the two reflective bodies 1410 can be disposed on the same side or on different sides, as long as they can mix the light emitted by the color resists 1210 of adjacent colors.

[0076] The sizes of the two reflective bodies 1410 may be the same or different, and may be specifically designed according to different embodiments.

[0077] In some embodiments, the reflective unit 141 includes a hemispherical reflective body 1410 , and a reflective member 1420 is attached to the outer side of the reflective body 1410 . One end of the reflective member 1420 is connected to the base substrate 110 , and the other end is extended along the outer wall of the reflective body 1410 .

[0078] It is worth mentioning that when viewing the display panel 100 from the side where the reflector 1420 is provided, since the side of the reflector 1420 away from the reflective body 1410 is covered by the black matrix 130, and the reflector 1420 is not provided on the other side of the reflective body 1410, when viewing the display panel 100 from the side where the reflector 1420 is provided, the external light will be completely absorbed by the black matrix 130, will not be emitted from the reflective body 1410, will not interfere with information reading, and will ensure information sharing.

[0079] When viewing the display panel 100 from a side where the reflector 1420 is not provided, part of the external light will be reflected on the reflector 1420, and part of the light will be reflected from the reflector 1420 out of the reflective body 1410, and will be mixed with the light emitted by the adjacent color resist 1210, and the other part of the light will be absorbed by the black matrix 130 after being reflected by the reflector 1420, and will not be emitted from the reflective body 1410, thereby ensuring information reading. When viewing the display panel 100 from a side where the reflector 1420 is not provided, the other part of the external light will be absorbed by the black matrix 130, and will not be mixed with the light emitted by the adjacent color resist 1210, thereby ensuring normal information reading.

[0080] That is to say, the reflective body 1410 and the reflective member 1420 disposed outside the reflective body 1410 can achieve partial anti-peeping, thereby ensuring the privacy of information. Moreover, by covering the reflective body 1410 and the reflective member 1420 with the black matrix 130, the location of the anti-peeping unit can be reduced, thereby reducing the thickness of the display panel 100, thereby reducing the cost of manufacturing the display panel 100. Moreover, under the normal viewing angle, external light will not be emitted from the reflective body 1410, thereby ensuring the display effect under the normal viewing angle.

[0081] It is worth mentioning that the preparation method of the reflection unit 141 is as follows:

[0082] Step S100, providing a base substrate 110;

[0083] Step S200, forming a transparent photoresist on the base substrate 110, and performing yellow light exposure, development and other processes on the transparent photoresist to obtain a hemispherical or quasi-hemispherical reflective unit 141;

[0084] Step S300, a metal layer is coated on the outer surface of the reflective unit 141 by physical vapor deposition (PVD), and the metal layer can be made of a highly reflective material, such as copper, aluminum, etc., and a dry etching process is performed on the metal layer to form the reflective element 1420;

[0085] Step S400 , preparing a black matrix 130 and a color resist unit 121 on the base substrate 110 , the color resist unit 121 and the reflective unit 141 are arranged at intervals, and the black matrix 130 completely covers the reflective unit 141 .

[0086] Embodiment 2

[0087] The difference between the second embodiment of the present application and the first embodiment is that the reflection unit 141 in the second embodiment of the present application includes a first reflection body 1411 and a second reflection body 1412 that are interconnected, which can increase its anti-peeping viewing angle.

[0088] In the examples of this application, see Figures 5 to 7 As shown, the reflection unit 141 includes a first reflection body 1411 and a second reflection body 1412. Both the first reflection body 1411 and the second reflection body 1412 adopt a spherical segment structure. The outer wall surfaces of the first reflection body 1411 and the second reflection body 1412 are arc surfaces. The first reflection body 1411 and the second reflection body 1412 are connected to each other.

[0089] It should be noted that see Figure 7 As shown, the reflective member 1420 is disposed on an outer wall surface of one of the first reflective body 1411 and the second reflective body 1412 .

[0090] In the embodiment of the present application, the reflector 1420 is disposed on the outer wall surface of the first reflective body 1411, and its coverage area should be less than half of the surface area of ​​the first reflective body 1411. By opening the second reflective body 1412 on one side of the first reflective body 1411, the light originally absorbed by the black matrix 130 can be emitted from the connection between the second reflective body 1412 and the base substrate 110 to mix with the light emitted by the adjacent color resist 1210, thereby interfering with information acquisition.

[0091] It is understandable that when light enters a single reflective body 1410 along a certain angle, it is reflected from the reflective member 1420, and the reflected light is absorbed by the black matrix 130 and cannot be emitted from the connection between the reflective body 1410 and the base substrate 110. When the light in the present application enters the first reflective body 1411 along the same angle, the light is reflected along the same reflection path at the reflective member 1420. Since a second reflective body 1412 is provided on one side of the first reflective body 1411, the reflected light is not blocked by the black matrix. At this time, the reflected light will continue to be emitted along the reflection path; the reflected light will be emitted from the connection between the second reflective body 1412 and the base substrate 110, and mixed with the adjacent color resist 1210, interfering with information acquisition, and achieving anti-peeping.

[0092] That is to say, the second reflective body 1412 and the first reflective body 1411 can increase the overlapping area between the reflective unit 141 and the base substrate 110, thereby increasing the light emission area and achieving more angles of privacy protection.

[0093] Furthermore, in order to ensure that the normal viewing angle light will not be reflected from the first reflective body 1411 when it is incident on the reflective element 1420 , the arc length corresponding to the reflective element 1420 in the cross section along the thickness direction of the base substrate 110 is less than πr / 3, where r is the radius of the first reflective body 1411 .

[0094] It can be understood that in some embodiments, this reflective element 1420 can also be arranged on the outer wall surface of the first reflective body 1411 and the second reflective body 1412, that is, the outer wall surface of the first reflective body 1411 and the second reflective body 1412 are both provided with a reflective element 1420, so that anti-peeping in a larger viewing angle range can be achieved, thereby improving the anti-peeping function.

[0095] It should be noted that the radii of the first reflective body 1411 and the second reflective body 1412 may be the same or different.

[0096] In the embodiment of the present application, the radii of the first reflective body 1411 and the second reflective body 1412 are different, and the radius of the first reflective body 1411 is greater than the radius of the second reflective body 1412. The arc surface of the first reflective body 1411 is connected to the arc surface of the second reflective body 1412.

[0097] Embodiment 3

[0098] The difference between the third embodiment of the present application and the first and second embodiments is that the third embodiment uses the light of the display panel 100 itself to prevent peeping.

[0099] In the embodiment of the present application, the display panel 100 further includes a light emitting portion, and the light emitted by the light emitting portion can be emitted through the color resist 1210 , thereby presenting a corresponding color or increasing the color brightness.

[0100] It should be noted that, depending on the display panel 100, this light-emitting portion also corresponds to different positions. When the display panel 100 is a liquid crystal display panel 100, the light-emitting portion is an LED lamp bead on the backlight module. The light emitted by the lamp bead is emitted to the liquid crystal layer in the display panel 100 through the diffusion plate on the backlight module, and then emitted to the color resistance 1210 in the opposing substrate to present different colors. When the display panel 100 is an organic light-emitting diode, the light-emitting portion is the organic light-emitting layer in the organic light-emitting diode. The anode and cathode are used to drive the organic light-emitting layer to emit light of corresponding colors, and then emit it to the color resistance 1210 above the encapsulation layer, thereby improving the color of the light.

[0101] Of course, the display panel 100 is not fixed to the liquid crystal display panel 100 and the organic light emitting diode, and may also be other types of display panels 100 .

[0102] In the examples of this application, see Figure 8 and Fig. 9 As shown, the black matrix 130 covers a portion of the reflective unit 141 , and the reflective member 1420 is disposed outside the reflective unit 141 . The reflective member 1420 can reflect the light emitted by the light emitting portion, and the reflected light can be emitted from the base substrate 110 side.

[0103] It can be understood that since the light at the original black matrix 130 will not be emitted from the black matrix 130 and will not participate in the display, after the reflection unit 141 is added in the present application, part of the light emitted by the light-emitting part will not be absorbed by the black matrix 130, but will be emitted from the reflection unit 141 and the reflection member 1420, and will be mixed with the light of the adjacent color resist 1210, thereby interfering with the information reading under normal viewing angle, thereby playing an anti-peeping role.

[0104] By mixing the light generated by the light-emitting portion itself with the adjacent color resist 1210, anti-peeping can be performed in a dark state, further improving the anti-peeping effect.

[0105] In the examples of this application, see Fig. 9As shown, the black matrix 130 includes a first light shielding portion 131, a second light shielding portion 132 and a third light shielding portion 133, the second light shielding portion 132 and the third light shielding portion 133 are respectively arranged on opposite sides of the first light shielding portion 131, and the second light shielding portion 132 and the third light shielding portion 133 are spaced from the first light shielding portion 131. The reflection unit 141 includes a third reflection body 1413 and a fourth reflection body 1414, the third reflection body 1413 is arranged in the gap between the first light shielding portion 131 and the second light shielding portion 132, and the fourth reflection body 1414 is arranged in the gap between the first light shielding portion 131 and the third light shielding portion 133; the third reflection body 1413 is provided with a reflection member 1420 on one side close to the first light shielding portion 131 and on one side close to the second light shielding portion 132, and the fourth reflection body 1414 is provided with a reflection member 1420 on one side close to the first light shielding portion 131 and on one side close to the third light shielding portion 133.

[0106] In order to ensure the anti-peeping effect, the third reflective body 1413 and the fourth reflective body 1414 are both arranged at an angle with the base substrate 110, that is, the third reflective body 1413 and the fourth reflective body 1414 have an angle with the base substrate 110. The light emitted from the light-emitting portion at a normal viewing angle will not be emitted from the third reflective body 1413 and the fourth reflective body 1414, ensuring that information can be read at a normal viewing angle. For the light in other directions, the reflective members 1420 on the front and rear sides of the third reflective body 1413 and the fourth reflective body 1414 can be used to reflect the light multiple times and emit it from the third reflective body 1413 and the fourth reflective body 1414.

[0107] Since the third reflective body 1413 and the fourth reflective body 1414 are tilted, the first light shielding portion 131 and the second light shielding portion 132 are parallel to each other, and the first light shielding portion 131 and the third light shielding portion 133 are parallel to each other, so as to ensure that the light of the light emitting portion can be emitted.

[0108] The light generated by the reflective unit 141, the reflective member 1420 and the light emitting part itself is used to realize anti-peeping in a dark state, thereby improving the anti-peeping effect.

[0109] It is worth mentioning that in order to prepare the display panel 100, a black matrix 130 is pre-arranged on the base substrate 110, and the first light shielding portion 131 is prepared by exposure and development techniques, and then a metal layer is prepared on the outer surface of the first light shielding portion 131 to prepare the reflector 1420, and then the third reflective body 1413 and the fourth reflective body 1414 are formed on the side of the reflector 1420 away from the first light shielding portion 131. After the preparation is completed, a reflective member 1420 is prepared on the outer surface of the third reflective body 1413 and the fourth reflective body 1414, and finally the second light shielding portion 132 and the third light shielding portion 133 are prepared to complete the preparation of the above display panel 100.
