Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Example one
Referring to fig. 1, a schematic plan view of a display panel according to an embodiment of the present invention is shown, and fig. 2 is a schematic cross-sectional view of a display panel in a photosensitive area according to an embodiment of the present invention.
In the embodiment of the present invention, the display panel is divided into a display area 10 and a photosensitive area 20 corresponding to the photosensitive device; the display panel located in the photosensitive region 20 includes a first array substrate 21, a first color filter substrate 22, and a first liquid crystal layer 23 located between the first array substrate 21 and the first color filter substrate 22; the first color filter substrate 22 includes a first color resist layer 221, the first color resist layer 221 includes a first color resist unit 2211, a second color resist unit 2212 and a white color resist unit 2213, and colors of light rays allowed to pass through the first color resist unit 2211, the second color resist unit 2212 and the white color resist unit 2213 are different.
In the embodiment of the present invention, as shown in fig. 1, the display panel includes a display area 10 and a photosensitive area 20, the photosensitive area 20 corresponds to a position of the photosensitive device, and external ambient light enters the photosensitive device through the display panel in the photosensitive area 20, so that the photosensitive device realizes a corresponding function.
Fig. 2 is a cross-sectional view taken along a1-a2 in fig. 1, and as shown in fig. 2, the display panel located in the photosensitive region 20 includes a first array substrate 21, a first color filter substrate 22, and a first liquid crystal layer 23 located between the first array substrate 21 and the first color filter substrate 22. The first color filter substrate 22 includes a first color resist layer 221 and a first substrate 222, where the first color resist layer 221 is located on a side of the first substrate 221 of the first color filter substrate 22 facing the first array substrate 21, of course, the first color resist layer 221 may also be located on a side of the first substrate 222 of the first color filter substrate 22 facing away from the first array substrate 21, and the specific position of the first color resist layer 221 is not limited in this embodiment of the present invention.
The first color resistance layer 221 includes a first color resistance unit 2211, a second color resistance unit 2212 and a white color resistance unit 2213, the first color resistance unit 2211, the second color resistance unit 2212 and the white color resistance unit 2213 are all made of organic materials, such as resin, but different color filter materials are doped in the organic materials corresponding to the first color resistance unit 2211 and the second color resistance unit 2212, so that the colors of the light rays allowed to pass through the first color resistance unit 2211, the second color resistance unit 2212 and the white color resistance unit 2213 are different.
Further, the first color resist 2211, the second color resist 2212, and the white color resist 2213 are provided in the same layer on the first substrate 222.
In the related art, the color resistance layer includes three different color resistance units, and each color resistance unit only allows light of one color to pass through, including red color resistance unit, green color resistance unit and blue color resistance unit if the color resistance layer, thereby when making outside environment light enter into the sensitization device corresponding to sensitization region 20 through display panel, a large amount of outside environment light can be filtered by display panel, display panel's transmissivity is low, make only a small amount of outside environment light enter into the sensitization device, thereby the sensitization effect of sensitization device has been influenced.
In the embodiment of the present invention, the first color resist layer 221 includes the white color resist unit 2213, the white color resist unit 2213 does not filter the light of the specific color, and the white color resist unit 2213 absorbs less light, so that when external ambient light enters the display panel from the first color film substrate 22, the display panel located at the photosensitive region 20 absorbs less external ambient light, so that more external ambient light can enter the photosensitive device corresponding to the photosensitive region 20 through the display panel, and the photosensitive device can obtain more external ambient light, so as to improve the photosensitive effect of the photosensitive device.
For example, when the photosensitive device is a camera, the white color resistance unit 2213 is disposed in the display panel located in the photosensitive region 20, so that the light transmittance of the display panel located in the photosensitive region 20 is increased, more external ambient light entering the display panel from the first color film substrate 22 passes through the display panel and enters the camera, and the imaging effect of the camera can be improved.
In the embodiment of the present invention, the liquid crystal molecules of the first liquid crystal layer 23 are dye liquid crystal molecules. For example, the dye liquid crystal molecules of the first liquid crystal layer 23 may be negative anthraquinone-type dichroic dye liquid crystal molecules.
By setting the liquid crystal molecules of the first liquid crystal layer 23 located between the first color film substrate 22 and the first array substrate 21 as dye liquid crystal molecules, and applying different electric fields to the dye liquid crystal molecules, the dye liquid crystal molecules in the first liquid crystal layer 23 can be controlled to be in a light transmitting state or a light absorbing state.
When the dye liquid crystal molecules are in a light-transmitting state, light passing through the first liquid crystal layer 23 can pass through the first liquid crystal layer 23, and compared with the traditional liquid crystal molecules, the dye liquid crystal molecules absorb little light, so that the light transmittance of the first liquid crystal layer 23 can be improved, and further the transmittance of the display panel is improved.
For example, for the display panel located in the photosensitive region 20, when external ambient light enters the first liquid crystal layer 23 through the first color film substrate 22, the first liquid crystal layer 23 may reduce absorption of the external ambient light, so that light loss of the external ambient light passing through the first liquid crystal layer 23 is reduced, that is, light transmittance of the first liquid crystal layer 23 is improved; when the light passing through the first array substrate 21 enters the first liquid crystal layer 23, the first liquid crystal layer 23 can also reduce absorption of the light passing through the first array substrate 21 entering the first liquid crystal layer 23, so that more light reaches the first color film substrate 22, and the light transmittance of the display panel is further improved.
When the dye liquid crystal molecules are in a light-absorbing state, the first liquid crystal layer 23 transmits light of a specific wavelength and absorbs light of other wavelengths. The first liquid crystal layer 23 may transmit light of any one color of blue light, red light, and green light by selecting different dye liquid crystal molecules.
For example, when the first color resist 2211 is a red color resist and the second color resist 2212 is a green color resist, the first color resist 2211 allows red light to pass through and the second color resist 2212 allows green light to pass through, at this time, dye liquid crystal molecules transmitting blue light can be selected, by controlling the dye liquid crystal molecules at the corresponding area of the white color resist 2213 to be in a light absorption state, so that the light passing through the dye liquid crystal molecules at the corresponding area of the white color resist 2213 is changed from white light to blue light, and then the blue light passes through the white color resist 2213 and exits from the light exit surface of the display panel. Of course, the first color resistance unit 2211 can also be a green color resistance unit, and the second color resistance unit 2212 can be a red color resistance unit.
When the first color resistance unit 2211 is a green color resistance unit, and the second color resistance unit 2212 is a blue color resistance unit, the first color resistance unit 2211 allows green light to pass through, and the second color resistance unit 2212 allows blue light to pass through, at this time, dye liquid crystal molecules transmitting red light can be selected, by controlling the dye liquid crystal molecules at the corresponding region of the white color resistance unit 2213 to be in a light absorption state, so that the light passing through the dye liquid crystal molecules at the corresponding region of the white color resistance unit 2213 is changed from white light to red light, and then the red light passes through the white color resistance unit 2213 to be emitted from the light emitting surface of the display panel. Of course, the first color resistance unit 2211 can also be a blue color resistance unit, and the second color resistance unit 2212 can be a green color resistance unit.
When the first color resistance unit 2211 is a red color resistance unit, and the second color resistance unit 2212 is a blue color resistance unit, the first color resistance unit 2211 allows red light to pass through, and the second color resistance unit 2212 allows blue light to pass through, at this time, dye liquid crystal molecules transmitting green light can be selected, by controlling the dye liquid crystal molecules at the corresponding region of the white color resistance unit 2213 to be in a light absorption state, so that the light passing through the dye liquid crystal molecules at the corresponding region of the white color resistance unit 2213 is changed from white light to green light, and then the green light passes through the white color resistance unit 2213 to be emitted from the light emitting surface of the display panel. Of course, the first color resistance unit 2211 can also be a blue color resistance unit, and the second color resistance unit 2212 can be a red color resistance unit.
The selection of the specific dye liquid crystal molecules may be determined according to the color of the light allowed to pass through the first color resist unit 2211 and the second color resist unit 2212, as long as the color of the light transmitted by the dye liquid crystal molecules is different from the color of the light allowed to pass through the first color resist unit 2211 and the second color resist unit 2212, so that the display panel of the light sensing region 20 can normally display.
In the embodiment of the present invention, as shown in fig. 3, the display panel located in the photosensitive region 20 further includes a photoluminescent layer 25 disposed between the first liquid crystal layer 23 and the first color filter substrate 22; the photoluminescent layer 25 has a first through hole 251 penetrating through, and the orthographic projection of the white color resistance unit 2213 on the photoluminescent layer 25 is located in the area where the first through hole 251 is located; the photo-luminescent layer 25 is configured to excite a first light and a second light under the action of light incident on the photo-luminescent layer 25 through the first array substrate 21; the first light has the same color as the light allowed to pass through the first color resist 2211, and the second light has the same color as the light allowed to pass through the second color resist 2212.
In the embodiment of the present invention, the display panel located in the photosensitive region 20 further includes a photoluminescent layer 25, the photoluminescent layer 25 is located between the first liquid crystal layer 23 and the first color film substrate 22, a first through hole 251 is disposed in the photoluminescent layer 25, the first through hole 251 penetrates through the photoluminescent layer 25 in a direction perpendicular to the light exit surface of the display panel, and an orthogonal projection of the white color resist unit 2213 located in the first color film substrate 22 on the photoluminescent layer 25 is located in a region where the first through hole 251 is located. The area of the orthographic projection of the white color resistance unit 2213 on the first substrate 222 may be equal to the area of the orthographic projection of the first through hole 251 on the first substrate 222, or the area of the orthographic projection of the white color resistance unit 2213 on the first substrate 222 may be smaller than the area of the orthographic projection of the first through hole 251 on the first substrate 222, which is not limited in the embodiment of the present invention.
By making the white color resistance unit 2213 correspond to the first through hole 251 in the photoluminescent layer 25, the light incident on the first liquid crystal layer 23 through the first array substrate 21 can not be converted into light of other colors by the photoluminescent layer 25, thereby ensuring that the color of the light passing through the white color resistance unit 2213 is the color of the light allowed to pass through by the first liquid crystal layer 23.
When there is light incident on the photoluminescent layer 25 through the first array substrate 21, the photoluminescent layer 25 is excited by the incident light to generate a first light and a second light, where the first light has the same color as the light allowed to pass through the first color-resisting unit 2211, and the second light has the same color as the light allowed to pass through the second color-resisting unit 2212. And the color of the light passing through the white color resistance unit 2213 is different from the color of the light passing through the first color resistance unit 2211 and the color of the light passing through the second color resistance unit 2212, thereby providing a rich color display effect for the display panel.
In addition, there is no overlapping area between the orthographic projection of the first color resistance unit 2211 and the second color resistance unit 2212 on the photoluminescent layer 25 and the first through hole 251, because of the arrangement of the photoluminescent layer 25, more first light rays allowed to pass through by the first color resistance unit 2211 and more second light rays allowed to pass through by the second color resistance unit 2212 are generated, and therefore, the intensity of the light rays passing through the first color resistance unit 2211 and the intensity of the light rays passing through the second color resistance unit 2212 are increased, thereby improving the display effect of the display panel, and simultaneously improving the transmittance of the display panel.
In the embodiment of the present invention, the white color resist unit 2213 is disposed in the first color resist layer 221, and the photoluminescent layer 25 is disposed between the first liquid crystal layer 23 and the first color film substrate 22, so that the transmittance of the display panel located in the photosensitive region 20 is increased, the transmittance of the conventional display panel is only 6% to 8%, and the transmittance of the display panel located in the photosensitive region in the embodiment of the present invention may reach 15% to 20%.
In the embodiment of the present invention, as shown in fig. 3, the display panel located in the photosensitive region 20 further includes a first protective layer 26 and a second protective layer 27, where the first protective layer 26 is disposed between the photoluminescent layer 25 and the first color filter substrate 22, and the second protective layer 27 is disposed between the photoluminescent layer 25 and the first liquid crystal layer 23.
In the embodiment of the present invention, the display panel located in the photosensitive region 20 further includes a first protective layer 26 and a second protective layer 27 respectively disposed on two sides of the photoluminescent layer 25, the first protective layer 26 is located between the photoluminescent layer 25 and the first color filter substrate 22, the second protective layer 27 is located between the photoluminescent layer 25 and the first liquid crystal layer 23, and both the first protective layer 26 and the second protective layer 27 are formed by resin molecules.
Moreover, the light transmittance of the first protective layer 26 and the second protective layer 27 is 98%, which ensures that light passing through the first protective layer 26 and the second protective layer 27 is not excessively lost, and the first protective layer 26 and the second protective layer 27 are used for protecting the photoluminescent layer 25 sandwiched between the first protective layer 26 and the second protective layer 27, so as to avoid the problem that the photoluminescent layer 25 fails due to the influence of impurities in the first liquid crystal layer 23 or the first color film substrate 22 on the photoluminescent layer 25, and therefore, the first protective layer 26 and the second protective layer 27 can ensure that the photoluminescent layer 25 is normally used to excite the first light and the second light.
In the embodiment of the present invention, the display panel located in the photosensitive region 20 further includes a first electrode layer 28, the first electrode layer 28 is located between the first array substrate 21 and the first liquid crystal layer 23; wherein the first electrode layer 28 comprises a plurality of electrode units.
In the embodiment of the present invention, the display panel located in the photosensitive region 20 further includes a first electrode layer 28, the first electrode layer 28 is located between the first array substrate 21 and the first liquid crystal layer 23, the first electrode layer 28 includes a plurality of independent electrode units, adjacent electrode units are electrode groups with opposite polarities, and different voltages are applied to each electrode group to control dye liquid crystal molecules in the first liquid crystal layer 23 at a position corresponding to each electrode group to be in a light transmitting state or a light absorbing state, so as to adjust transmittance of the dye liquid crystal molecules to light. Because each electrode group can be independently controlled, the electrode group at the position corresponding to each color resistance unit can be independently controlled, and the light transmission state of the dye liquid crystal molecules at the position corresponding to each color resistance unit can be controlled.
For example, when the photosensitive device is in a dormant state, that is, when the display panel located in the photosensitive region 20 displays, by applying a first voltage to each electrode group located at the corresponding position of the white color resistance unit 2213, the dye liquid crystal molecules located at the corresponding position of the white color resistance unit 2213 are under a first electric field, and the dye liquid crystal molecules in the region are controlled to be in a light absorption state, as shown in fig. 5, at this time, the dye liquid crystal molecules absorb part of light rays irradiated thereon, and only light rays with specific wavelengths are allowed to pass through the dye liquid crystal molecules. By applying a second voltage to each electrode group at the corresponding positions of the first color resistance unit 2211 and the second color resistance unit 2212, the dye liquid crystal molecules at the corresponding positions of the first color resistance unit 2211 and the second color resistance unit 2212 are under a second electric field, the dye liquid crystal molecules in the region are controlled to be in a light transmission state, and then the light passing through the first array substrate 21 is completely transmitted at the dye liquid crystal molecules at the corresponding positions of the first color resistance unit 2211 and the second color resistance unit 2212.
