[0046] Embodiment one
[0047] The present application provides a display panel 100, which can be a liquid crystal display panel 100 (LCD) or an organic light emitting diode (OLED).
[0048] Referring to Figure 1 and Figure 2 , the display panel 100 includes a substrate 110, a color resistance layer, a black matrix 130 (BM) and a reflective layer.
[0049] The substrate 110 can be a glass substrate, but is not limited thereto, and can also be a substrate of other materials, such as PI material, etc.
[0050] Referring to Figure 1 , the color resistance layer includes a plurality of arrayed color resistance units 121, and the plurality of color resistance units 121 are sequentially and spacedly arranged in the row direction X and the column direction Y. Each color resistance unit 121 includes a plurality of color resistances 1210, the light emitting colors of adjacent color resistances 1210 are different, and the black matrix 130 is arranged between adjacent color resistances 1210 to isolate the light between adjacent color resistances 1210 and prevent affecting the visual effect.
[0051] For example, as shown in Figure 1 Each color resist unit 121 includes a red color resist, a green color resist, and a blue color resist. The color resists 1210 in the same column direction Y have the same light-emitting color, and the red color resists, the green color resists, and the blue color resists in the same row direction X are arranged at intervals.
[0052] It can be understood that the color resist layer can be designed at different positions according to the type of the 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 arranged on the side of the encapsulation layer, and the color resists 1210 in the color resist layer correspond to the light-emitting parts of the organic light-emitting diodes respectively, so as to increase the light color and improve the visual effect.
[0053] In the embodiment of the present application, as shown in Figure 2 The reflective layer is arranged on the substrate 110, and the reflective layer includes a plurality of transparent reflective units 141. At least part of the reflective units 141 is covered by the black matrix 130, and the reflective units 141 and the color resists 1210 are arranged at intervals, so as to avoid that the reflective units 141 occupy too much pixel opening and improve the pixel aperture ratio.
[0054] In the embodiment of the present application, as shown in Figure 2 and Figure 3 The surface of the reflective unit 141 is provided with a reflecting member 1420. The reflecting member 1420 can be used for reflecting light. The light reflected by the reflecting member 1420 can mix with the light emitted by the color resists 1210, so as to interfere with information acquisition and realize the 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 reflecting member 1420, and the light reflected at the reflecting member 1420 mixes with the light emitted by the color resists 1210, so as to interfere with information acquisition and realize the anti-peeping mode.
[0056] The reflective unit 141 and the reflecting member 1420 in the present application are embedded in the black matrix 130, which can realize anti-peeping, reduce the design position of the reflective unit 141 and the reflecting member 1420, reduce the thickness of the display panel 100, and reduce the cost of the display panel 100. That is, the present application can realize anti-peeping while reducing the thickness of the display panel 100 and reducing the preparation cost of the entire display panel 100.
[0057] In the embodiment of the present application, as shown in Figure 1As shown, the reflection unit 141 is arranged between two adjacent color resistance units 121 in the column direction Y, i.e., the reflection unit 141 is located between two rows of color resistance units 121, so as to avoid occupying the gap between adjacent color resistance units 1210, and to ensure the pixel aperture ratio while preventing peep.
[0058] It is worth mentioning that the reflection member 1420 can reflect external light, and the reflected external light and the light emitted by the color resistance unit 1210 can interfere with information acquisition, thereby realizing the anti-peep function. The reflection member 1420 can also reflect its own light, and the reflection member 1420 reflects different light according to the type of the display panel 100. For example, when the display panel 100 is a liquid crystal display panel 100, the reflection member 1420 reflects the light emitted by the backlight module; when the display panel 100 is an organic light-emitting diode, the reflection member 1420 reflects the light emitted by the light-emitting part.
[0059] In the embodiment of the present application, the reflection member 1420 can reflect external light, and the reflected external light and the light emitted by the color resistance unit 1210 can interfere with information acquisition, thereby realizing the anti-peep mode.
[0060] It should be noted that the reflection member 1420 can be arranged on the inner surface of the reflection unit 141 or on the outer surface of the reflection member 1420, as long as it can reflect external light.
[0061] In the embodiment of the present application, referring to Figure 2 and Figure 3 As shown, the black matrix 130 completely covers the reflection unit 141 and the reflection member 1420. The reflection member 1420 is arranged on the outer surface of the reflection unit 141. Compared with the scheme in which the reflection member 1420 is arranged on the inner surface of the reflection unit 141, the design is simpler, and a layer of reflection member 1420 does not need to be arranged inside the reflection unit 141, but only needs to be designed on the outer surface of the reflection unit 141.
[0062] It can be understood that the black matrix 130 completely covers the reflection unit 141 and the reflection member 1420, which is equivalent to arranging a plurality of groove structures on the black matrix 130, and the reflection unit 141 with the reflection member 1420 is embedded in the groove structure.
[0063] By covering the reflection unit 141 and the reflection member 1420 with the black matrix 130, the anti-peep function can be realized, and the thickness and weight of the entire display panel 100 can be reduced, 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 curved or planar, as long as it can reflect part of the external light out of the reflection unit 141 to achieve the privacy protection.
[0065] In the embodiment of the present application, as shown in Figure 3 The outer wall surface of the reflection unit 141 is curved. The reflecting member 1420 is attached to the outer wall surface of the reflection unit 141. External light enters the reflection unit 141 from the substrate 110 side. Part of the external light is reflected at the reflecting member 1420. The external light reflected by the reflecting member 1420 is partially reflected in the reflection unit 141 and absorbed by the black matrix 130. Another part of the reflected light exits the reflection unit 141 and mixes with the light emitted by the adjacent color filter 1210, forming reflected light, which interferes with information reading and achieves the privacy protection function. Another part of the external light is absorbed by the black matrix 130.
[0066] It can be understood that the curved surface can ensure that the external light within a certain angle range enters the reflection unit 141 without exiting the reflection unit 141 and being absorbed by the black matrix 130. External light within other angles can exit the reflection unit 141 through the reflecting member 1420 to mix with the light emitted by the adjacent color filter 1210, thereby achieving the privacy protection function.
[0067] In addition, the reflection unit 141 can be a spherical segment structure or other curved surface structure, as long as the light can be reflected out of the reflection unit 141 when it hits the reflecting member 1420.
[0068] In the embodiment of the present application, as shown in Figure 3 and Figure 4 The reflection unit 141 is a spherical segment structure, and the curved surface is an arc surface. The reflection unit 141 can include at least one semi-spherical reflection body 1410 embedded in the black matrix 130. Each reflection body 1410 has a reflecting member 1420 attached to its outer wall surface. One end of the reflecting member 1420 is connected to the substrate 110, and the other end extends along the outer wall surface of the reflection body 1410. The reflecting member 1420 embedded in the black matrix 130 reflects external light. The coverage area of the reflecting member 1420 is less than half the surface area of the reflection body 1410, so that in the normal viewing angle, external light will not exit the reflection body 1410, avoiding the reflection of external light affecting the display effect in the normal viewing angle and ensuring the brightness of light in the normal viewing angle.
[0069] It should be noted that the longitudinal section of the reflection unit 141 can be smaller than a semicircle, or larger than a semicircle, that is, the size of the position where the reflection unit 141 is connected to the substrate 110 is smaller than the diameter of the spherical structure, as long as the reflection unit 141 can emit light from the connection between the reflection unit 141 and the substrate 110.
[0070] In addition, the reflection body 1420 can also change its position according to the design shape of the reflection unit 141, as long as the reflection body 1420 can ensure that part of the external light is emitted from the connection between the reflection unit and the substrate 110, and the emitted light is mixed with the light emitted by the adjacent color resist 1210.
[0071] It is worth mentioning that the side of the display panel 100 facing the normal view is the normal view angle, when the external light at the normal view angle and a certain angle enters the reflection body 1410, the light will be reflected at the reflection body 1420, and the reflected light is absorbed by the black matrix 130 and cannot be emitted from the reflection body 1410 to mix with the light emitted by the adjacent color resist 1210, thereby ensuring information reading at the normal view angle and a certain angle. Another part of the external light at another angle enters the reflection body 1410, and the light at this angle is reflected at the reflection body 1420, and the light emitted from the reflection body 1410 is mixed with the light emitted by the adjacent color resist 1210, thereby interfering with information reading, and thus achieving the function of preventing peeping.
[0072] In the embodiment of the present application, in order to avoid the external light at the normal view angle from being emitted out of the reflection body 1410 through the reflection body 1420, the arc length corresponding to the reflection body 1420 in the cross section in the thickness direction of the substrate 110 is less than πr / 3, and r is the radius of the reflection body 1410.
[0073] In the embodiment of the present application, referring to FIGS. 1, 2 and 3, the reflection unit 141 includes two reflection bodies 1410, and the two reflection bodies 1410 are arranged at a distance from each other. Figure 2 and Figure 3 It can be understood that through the two reflection bodies 1410, the external light at a certain angle will be reflected out of the reflection body 1410 through the two reflection bodies 1420, and mixed with the light emitted by the adjacent color resist 1210, thereby increasing the number of external light participating in the mixing of light, improving the anti-peeping effect, and thus improving the anti-peeping effect.
[0074] It can be understood that through the two reflection bodies 1410, the external light at a certain angle will be reflected out of the reflection body 1410 through the two reflection bodies 1420, and mixed with the light emitted by the adjacent color resist 1210, thereby increasing the number of external light participating in the mixing of light, improving the anti-peeping effect, and thus improving the anti-peeping effect.
[0075] In addition, the reflectors 1420 on the two reflecting bodies 1410 can be arranged on the same side or different sides, as long as they can mix the light emitted by the adjacent color resist 1210.
[0076] The two reflecting bodies 1410 can have the same size or different sizes, which can be designed according to different embodiments.
[0077] In some embodiments, the reflection unit 141 includes a hemispherical reflecting body 1410, and the outer side of the reflecting body 1410 is attached with the reflector 1420, one end of the reflector 1420 is connected to the substrate 110, and the other end extends along the outer wall surface of the reflecting body 1410.
[0078] It is worth mentioning that when the display panel 100 is viewed from the side where the reflector 1420 is arranged, since the side of the reflector 1420 away from the reflecting body 1410 is covered by the black matrix 130, and the other side of the reflecting body 1410 is not provided with the reflector 1420, the external light will be completely absorbed by the black matrix 130 when the display panel 100 is viewed from the side where the reflector 1420 is arranged, and will not be emitted from the reflecting body 1410, which will not interfere with information reading and ensure information sharing.
[0079] When the display panel 100 is viewed from the side where the reflector 1420 is not arranged, part of the external light will be reflected on the reflector 1420, part of the light will be reflected out of the reflecting body 1410 from the reflector 1420, and 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 reflecting body 1410, which ensures information reading. When the display panel 100 is viewed from the side where the reflector 1420 is not arranged, 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, which ensures normal information reading.
[0080] That is, the reflecting body 1410 and the reflector 1420 arranged on the outer side of the reflecting body 1410 can realize local privacy protection and ensure the privacy of information. By covering the reflecting body 1410 and the reflector 1420 with the black matrix 130, the position of the privacy protection unit can be reduced, and the thickness of the display panel 100 can be reduced, thereby reducing the cost of preparing the display panel 100. In addition, under the normal viewing angle, the external light will not be emitted from the reflecting body 1410, which ensures 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 substrate 110;
[0083] Step S200, forming a transparent photoresist on the substrate 110, and performing processes such as photoexposure, development, etc. on the transparent photoresist to obtain a hemispherical or semi-hemispherical reflective unit 141;
[0084] Step S300, covering a metal layer on the outer surface of the reflective unit 141 by physical vapor deposition (PVD), the metal layer can be made of high-reflective material such as copper, aluminum, etc., and performing a dry etching process on the metal layer to form the reflective member 1420;
[0085] Step S400, preparing a black matrix 130 and a color resist unit 121 on the substrate 110, the color resist unit 121 is arranged in a spaced manner with the reflective unit 141, and the black matrix 130 completely covers the reflective unit 141.
[0086] Embodiment Two
[0087] The difference between the embodiment two and the embodiment one of the present application is that the reflective unit 141 in the embodiment two of the present application comprises a first reflective body 1411 and a second reflective body 1412 which are in communication with each other, so that the anti-peeping angle can be increased.
[0088] In the embodiment of the present application, as shown in Figures 5 to 7 The reflective unit 141 comprises the first reflective body 1411 and the second reflective body 1412, the first reflective body 1411 and the second reflective body 1412 are both in spherical segment structure, the outer wall surface of the first reflective body 1411 and the second reflective body 1412 is a circular arc surface, and the first reflective body 1411 and the second reflective body 1412 are in communication with each other.
[0089] It should be noted that, as shown in Figure 7 The reflective member 1420 is arranged on the 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 reflective member 1420 is arranged on the outer wall surface of the first reflective body 1411, and the covering area of the reflective member 1420 should be less than half of the surface area of the first reflective body 1411. By arranging 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 substrate 110 to mix with the light emitted by the adjacent color resist 1210, so as to interfere with the information acquisition.
[0091] It can be understood that when the light is incident into the single reflection body 1410 at a certain angle, the light is reflected from the reflecting member 1420, and the reflected light is absorbed by the black matrix 130 and cannot be emitted from the connection between the reflection body 1410 and the substrate 110. However, in the present application, when the light is incident into the first reflection body 1411 at the same angle, the light is reflected along the same reflection path at the reflecting member 1420. Since the second reflection body 1412 is arranged on one side of the first reflection body 1411, the reflected light is not blocked by the black matrix, and 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 reflection body 1412 and the substrate 110, and will mix with the light of the adjacent color resistance 1210, thereby interfering with the information acquisition and achieving the privacy protection.
[0092] That is, the second reflection body 1412 and the first reflection body 1411 can increase the overlapping area of the reflection unit 141 and the substrate 110, and further can increase the emission area of the light, thereby achieving the privacy protection in more angles.
[0093] In addition, in order to ensure that the light at the normal viewing angle will not be emitted from the first reflection body 1411 when the light is incident on the reflecting member 1420, the arc length corresponding to the reflecting member 1420 is less than πr / 3 in the cross section of the substrate 110 in the thickness direction, and r is the radius of the first reflection body 1411.
[0094] It can be understood that in some embodiments, the reflecting member 1420 can also be arranged on the outer wall surface of the first reflection body 1411 and the second reflection body 1412, that is, the reflecting member 1420 is arranged on the outer wall surface of the first reflection body 1411 and the second reflection body 1412, thereby achieving the privacy protection in a larger viewing angle range and improving the privacy protection function.
[0095] It should be noted that the radii of the first reflection body 1411 and the second reflection body 1412 can be the same or different.
[0096] In the embodiments of the present application, the radii of the first reflection body 1411 and the second reflection body 1412 are different, and the radius of the first reflection body 1411 is greater than the radius of the second reflection body 1412. The circular arc surface of the first reflection body 1411 is connected with the circular arc surface of the second reflection body 1412.
[0097] Embodiment Three
[0098] The difference between the embodiment three and the embodiment one and the embodiment two is that the embodiment three uses the light of the display panel 100 itself for privacy protection.
[0099] In the embodiment of the present application, the display panel 100 further comprises a light emitting part, and the light emitted by the light emitting part can pass through the color filter 1210 and then be emitted out, thereby presenting corresponding colors or improving color brightness.
[0100] It should be noted that the light emitting part corresponds to different positions according to different display panels 100. When the display panel 100 is a liquid crystal display panel 100, the light emitting part is an LED lamp bead on a backlight module, the light emitted by the lamp bead passes through a diffusion plate on the backlight module, is emitted to a liquid crystal layer in the display panel 100, and then is emitted to the color filter 1210 in the opposite substrate, so as to present different colors. When the display panel 100 is an organic light emitting diode, the light emitting part is an organic light emitting layer in the organic light emitting diode, the organic light emitting layer is driven by an anode and a cathode to emit light of corresponding colors, and then the light is emitted to the color filter 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 can be other types of display panels 100.
[0102] In the embodiment of the present application, referring to FIG. 1, the display panel 100 comprises a substrate 110, a black matrix 130, a color filter 1210, a reflective unit 141, a reflector 1420, and a light emitting part. Figure 8 and Figure 9 As shown in the figures, the black matrix 130 covers part of the reflective unit 141, and the reflector 1420 is arranged outside the reflective unit 141. The reflector 1420 can reflect the light emitted by the light emitting part, and the reflected light can be emitted out from the side of the substrate 110.
[0103] It can be understood that, since the light at the original black matrix 130 will not be emitted out from the black matrix 130 and will not participate in display, after the reflective 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 out from the reflective unit 141 and the reflector 1420, and then the light will be mixed with the light of the adjacent color filter 1210, thereby interfering with information reading under normal viewing angle, and then playing a privacy protection role.
[0104] The light emitted by the light emitting part is mixed with the light of the adjacent color filter 1210, so that the privacy protection can be realized in a dark state, and the privacy protection effect is further improved.
[0105] In the embodiment of the present application, referring to FIG. 1, the display panel 100 comprises a substrate 110, a black matrix 130, a color filter 1210, a reflective unit 141, a reflector 1420, and a light emitting part. Figure 9As shown, the black matrix 130 includes a first light-blocking portion 131, a second light-blocking portion 132, and a third light-blocking portion 133. The second light-blocking portion 132 and the third light-blocking portion 133 are respectively arranged on opposite sides of the first light-blocking portion 131, and the second light-blocking portion 132 and the third light-blocking portion 133 are arranged in a spaced manner with the first light-blocking 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 a gap between the first light-blocking portion 131 and the second light-blocking portion 132, and the fourth reflection body 1414 is arranged in a gap between the first light-blocking portion 131 and the third light-blocking portion 133. The third reflection body 1413 is provided with a reflecting member 1420 on a side close to the first light-blocking portion 131 and a side close to the second light-blocking portion 132, and the fourth reflection body 1414 is provided with a reflecting member 1420 on a side close to the first light-blocking portion 131 and a side close to the third light-blocking portion 133.
[0106] In order to ensure the privacy protection effect, the third reflection body 1413 and the fourth reflection body 1414 are arranged in an inclined manner with the substrate 110, that is, the third reflection body 1413 and the fourth reflection body 1414 have an included angle with the substrate 110. The light emitted by the light-emitting portion in the normal viewing angle cannot be emitted from the third reflection body 1413 and the fourth reflection body 1414, thereby ensuring information reading in the normal viewing angle. The light in other directions can be reflected by the reflecting members 1420 on the front and back sides of the third reflection body 1413 and the fourth reflection body 1414, and then emitted from the third reflection body 1413 and the fourth reflection body 1414.
[0107] Due to the inclined arrangement of the third reflection body 1413 and the fourth reflection body 1414, the first light-blocking portion 131 and the second light-blocking portion 132 are arranged in parallel with each other, and the first light-blocking portion 131 and the third light-blocking portion 133 are arranged in parallel with each other, thereby ensuring the light emitted by the light-emitting portion.
[0108] The reflection unit 141, the reflecting members 1420, and the light emitted by the light-emitting portion are used to realize the privacy protection in a dark state, thereby improving the privacy protection effect.
[0109] It is worth mentioning that, in order to prepare the display panel 100, a black matrix 130 is provided on the substrate 110 in advance, and the first light shielding part 131 is prepared by exposure and development technology, and then a metal layer is prepared on the outer surface of the first light shielding part 131 to prepare the reflecting member 1420, and then the third reflecting body 1413 and the fourth reflecting body 1414 are formed on the side of the reflecting member 1420 away from the first light shielding part 131. After preparation, a layer of reflecting member 1420 is prepared on the outer surface of the third reflecting body 1413 and the fourth reflecting body 1414, and finally the second light shielding part 132 and the third light shielding part 133 are prepared to complete the preparation of the display panel 100 described above.
