Description

Display panel and display device
Technical Field
The present invention relates to the field of display technologies, and in particular, to a display panel and a display device.
Background
Quantum Dots (QDs), also called nanocrystals, are nanoparticles composed of elements of groups II-VI or III-V. The particle size of the quantum dot is generally between 1-20 nm, and because electrons and holes are limited by quanta, a continuous energy band structure is changed into a discrete energy level structure with molecular characteristics, and the quantum dot can emit fluorescence after being excited. In addition, quantum dots have a narrow Full Width at Half Maximum (FWHM) and yellow light with a wavelength of about 600nm is not transmitted, so that color saturation of a screen can be remarkably improved, and the quantum dots are widely concerned.
The current technology of quantum dots is applied to backlight. The quantum dot film layer is added into the backlight film, the quantum dots are excited by the blue light LED to generate green light and red light, and then the blue light green light and the red light are mixed to generate white light.
However, in the process of assembling the backlight module by the backlight film, the quantum dots at the edge part are sacrificed by cutting the backlight film, so that the green light and the red light at the edge are less, and the blue light at the edge is more when being mixed, so that when the backlight is used as the backlight source of the display panel, the periphery of the display panel presents a bluing phenomenon in the actual impression.
Disclosure of Invention
In view of the above, embodiments of the present invention provide a display panel and a display device, so as to solve the problem that the display panel is bluish around during displaying.
The display panel provided by the embodiment of the invention comprises a first substrate, a second substrate, a first orientation film, a second orientation film and at least three sub-pixels, wherein the first substrate and the second substrate are arranged oppositely; wherein,
the display panel is divided into a central area and a peripheral area surrounding the central area, and the peripheral area comprises at least one annular sub-area gradually extending from the edge of the display panel to the center of the display panel; a sub-pixel in the display panel, which presents a first color, is a preset sub-pixel, and in each annular sub-region:
the alignment angle of the first alignment film corresponding to the preset sub-pixel is smaller than the alignment angles of the first alignment films corresponding to other sub-pixels except the preset sub-pixel; and/or
The alignment angle of the second alignment film corresponding to the preset sub-pixel is smaller than the alignment angles of the second alignment films corresponding to other sub-pixels except the preset sub-pixel.
Correspondingly, the embodiment of the invention also provides a display device which comprises any one of the display panels provided by the embodiment of the invention.
The invention has the following beneficial effects:
in the display panel and the display device provided by the embodiment of the invention, the display panel is divided into the central area and the peripheral area surrounding the central area, and the peripheral area comprises at least one annular sub-area gradually extending from the edge of the display panel to the center of the display panel; in each annular sub-area, the alignment angle of the first alignment film corresponding to the preset sub-pixel is smaller than the alignment angles of the first alignment films corresponding to other sub-pixels except the preset sub-pixel; and/or the alignment angle of the second alignment film corresponding to the preset sub-pixel is smaller than the alignment angles of the second alignment films corresponding to other sub-pixels except the preset sub-pixel. Therefore, the light transmittance of the area corresponding to the preset sub-pixel is smaller than that of the areas corresponding to other sub-pixels, namely, the light transmittance of the first color in the annular sub-area is smaller than that of the other colors, so that the problem of color cast of the edge of the display panel caused by more light of a certain color than light of other colors at the edge of the backlight module can be compensated.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The shapes and sizes of the various elements in the drawings are not to scale and are merely intended to illustrate the invention.
As is well known, the liquid crystal display panel mainly controls the transmittance of liquid crystal by controlling the rotation of the liquid crystal using an electric field between a pixel electrode and a common electrode. According to the formula of liquid crystal transmittance:when the rotation angle psi of the liquid crystal is 45 degrees, the liquid crystal transmittance T is the largest, and when the rotation angle psi of the liquid crystal is 0 degree, the liquid crystal transmittance T is the smallest; when the rotation angle psi of the liquid crystal is less than 45 degrees, the smaller psi is, the smaller the liquid crystal transmittance T is; when the rotation angle Ψ of the liquid crystal is greater than 45 degrees and less than 90 degrees, the greater Ψ is, the greater the liquid crystal transmittance T is.
However, the inventor of the present invention found that, under a certain electric field, the alignment angle of the alignment film also affects the rotation angle of the liquid crystal, and the alignment angles of the alignment films in the display panel are set to 73 ° and 83 ° respectively to perform 3D simulation for verification, and a variation curve of the rotation angle Ψ of the liquid crystal according to the relative distance h of the liquid crystal from the array substrate is obtained through simulation, and as shown in fig. 1, as can be seen from fig. 1, the relative distance h from the array substrate is in a range of 54 to 57, and the rotation angle of the liquid crystal of the display panel with the alignment angle θ of 73 ° is greater than the rotation angle of the liquid crystal of the display panel with the alignment angle θ of 83 °. The liquid crystal transmittance formula is combined to show that the liquid crystal transmittance of the display panel with the alignment angle theta of 73 degrees is smaller than that of the display panel with the alignment angle theta of 83 degrees, so that researchers can obtain that the alignment angles are different, the liquid crystal rotation amplitudes are different, and correspondingly, the liquid crystal transmittance is different. Therefore, the phenomenon that the display panel of the existing display panel is blue due to the blue light bias of the edge of the backlight module can be improved by controlling the liquid crystal penetration rate of light with different colors.
In view of this, the display panel 1 according to the embodiment of the invention, as shown in fig. 2a, includes a first substrate 01 and a second substrate 02 disposed opposite to each other, a first alignment film 03 disposed on a side of the first substrate 01 facing the second substrate 02, a second alignment film 04 disposed on a side of the second substrate 02 facing the first substrate 01, and at least three sub-pixels with different colors; wherein,
as shown in fig. 2b (wherein, fig. 2b illustrates the first alignment film as an example), the display panel 1 is divided into a central region 1a and a peripheral region surrounding the central region 1a, and the peripheral region includes at least one annular sub-region 1b extending gradually from the edge of the display panel 1 to the center of the display panel 1; the sub-pixel of the display panel 1 showing the first color is a predetermined sub-pixel 11, and in each annular sub-region 1 b:
the alignment angle θ 1 of the first alignment film 03 corresponding to the predetermined sub-pixel 11 is smaller than the alignment angle θ 2 of the first alignment film 03 corresponding to the other sub-pixels 12 except the predetermined sub-pixel 11;
or the alignment angle of the second alignment film corresponding to the preset sub-pixel is smaller than the alignment angles of the second alignment films corresponding to other sub-pixels except the preset sub-pixel;
or the alignment angle of the first alignment film corresponding to the preset sub-pixel is smaller than the alignment angles of the first alignment films corresponding to the sub-pixels except the preset sub-pixel, and the alignment angle of the second alignment film corresponding to the preset sub-pixel is smaller than the alignment angles of the second alignment films corresponding to the sub-pixels except the preset sub-pixel.
In the display panel provided in the embodiment of the present invention, the display panel is divided into a central region and a peripheral region surrounding the central region, and the peripheral region includes at least one annular sub-region gradually extending from the edge of the display panel to the center of the display panel; in each annular sub-area, the alignment angle of the first alignment film corresponding to the preset sub-pixel is smaller than the alignment angles of the first alignment films corresponding to other sub-pixels except the preset sub-pixel; and/or the alignment angle of the second alignment film corresponding to the preset sub-pixel is smaller than the alignment angles of the second alignment films corresponding to other sub-pixels except the preset sub-pixel. Therefore, the light transmittance of the area corresponding to the preset sub-pixel is smaller than that of the areas corresponding to other sub-pixels, namely, the light transmittance of the first color in the annular sub-area is smaller than that of the other colors, so that the problem of color cast of the edge of the display panel caused by more light of a certain color than light of other colors at the edge of the backlight module can be compensated.
In the display panel provided in the embodiment of the present invention, the alignment angle refers to an included angle between an alignment direction of the alignment film and a predetermined direction, and the predetermined direction is generally perpendicular to an extending direction of the strip electrodes included in the pixel electrodes on the display panel. The preset direction and the alignment direction are both parallel to the surface of the substrate. Taking the pixel electrode as a dual-domain structure as an example, as shown in fig. 3, the predetermined direction S1 is perpendicular to the extending direction S2 of the stripe electrode 001, and the alignment angle θ is an included angle between the alignment direction S3 of the alignment film and the predetermined direction S1.
In specific implementation, in the display panel provided in the embodiment of the present invention, as shown in fig. 2a, a liquid crystal 05 is further disposed between the first alignment film 03 and the second alignment film 04.
In a specific implementation, in the display panel provided in the embodiment of the present invention, the display panel at least includes red sub-pixels, blue sub-pixels, and green sub-pixels. Of course, in the display panel provided in the embodiment of the present invention, the display panel may further include a white sub-pixel or a yellow sub-pixel, which is not limited herein.
In specific implementation, the backlight of the display panel at present is mainly that a blue LED excites quantum dots to generate green light and red light, and then the blue light, the green light and the red light are mixed to generate white light. However, such a backlight is easy to make the edge of the display panel shift blue when displaying, and therefore, in the display panel provided in the embodiment of the present invention, the predetermined sub-pixel is a blue sub-pixel, and the first color is blue. Therefore, the light transmittance of the area corresponding to the blue sub-pixel in the peripheral area of the display panel is reduced, and the problem that the peripheral area of the display panel is blue due to backlight can be compensated.
In a specific implementation manner, in the display panel provided in the embodiment of the present invention, the area of the peripheral region is determined according to a range of color shift of the backlight edge, and the larger the light variation edge color shift range is, the larger the area of the peripheral region of the display panel is.
In a specific implementation, in the display panel provided in the embodiment of the present invention, the peripheral region may include only one annular sub-region, and certainly, according to different degrees of color cast of the backlight edge, the peripheral region may also be divided into a plurality of annular sub-regions, so that different alignment angles may be adopted for different annular sub-regions to perform compensation.
In a specific implementation, in the display panel provided in the embodiment of the present invention, the light transmittance may be changed by setting the alignment angle of one of the alignment films, or certainly, the light transmittance may be changed by setting both the alignment angles of the two alignment films, which is not limited herein. It is most preferable to change the light transmittance by setting both the alignment angles of the two alignment films.
In a specific implementation, the farther the annular sub-region is from the central region, the more the backlight of the corresponding region deviates from the first color, the greater the light transmittance corresponding to the sub-pixels of the colors other than the first color in the annular sub-region, and the smaller the light transmittance corresponding to the sub-pixels of the first color. Therefore, in specific implementation, the number and the range of the annular sub-regions in the peripheral region can be designed according to the color cast degree of the backlight, and different annular sub-regions are gradually compensated according to the distance from the annular sub-region to the central region corresponding to different compensation degrees.
The following describes an implementation method of the display panel, in which the peripheral area includes at least two annular sub-areas.
Optionally, in the display panel provided in the embodiment of the present invention, the farther the annular sub-region is away from the central region, the larger the alignment angle of the first alignment film corresponding to the sub-pixel in the annular sub-region except the preset sub-pixel is;
or the farther the annular sub-area is away from the central area, the larger the alignment angle of the second alignment film corresponding to the sub-pixels except the preset sub-pixel in the annular sub-area is;
or, the farther the annular sub-region is from the central region, the larger the alignment angle of the first alignment film corresponding to the sub-pixels except the preset sub-pixel in the annular sub-region is, and the larger the alignment angle of the second alignment film corresponding to the sub-pixels except the preset sub-pixel in the annular sub-region is.
Therefore, in the annular sub-area which is farther away from the central area, the light transmittance of the areas corresponding to the sub-pixels except the preset sub-pixel is higher.
Optionally, in the display panel provided in the embodiment of the present invention, the farther the annular sub-region is from the central region, the smaller an alignment angle of the first alignment film corresponding to the preset sub-pixel in the annular sub-region is;
or the farther the annular sub-region is away from the central region, the smaller the alignment angle of the second alignment film corresponding to the preset sub-pixel in the annular sub-region is;
or, the farther the annular sub-region is from the central region, the smaller the alignment angle of the first alignment film corresponding to the predetermined sub-pixel in the annular sub-region is, and the farther the annular sub-region is from the central region, the smaller the alignment angle of the second alignment film corresponding to the predetermined sub-pixel in the annular sub-region is.
Therefore, the light transmittance of the area corresponding to the preset sub-pixel in the annular sub-area which is farther away from the central area is smaller.
In a specific implementation, in order to reduce the manufacturing difficulty, in the display panel provided in the embodiment of the present invention, the alignment angles of the first alignment films corresponding to the same color sub-pixels in each annular sub-region are equal; or the alignment angles of the second alignment films corresponding to the same color sub-pixels in each annular sub-area are equal; alternatively, the alignment angles of the first alignment films corresponding to the same color sub-pixels are equal for each annular sub-region, and the alignment angles of the second alignment films corresponding to the same color sub-pixels are equal for each annular sub-region.
As can be seen from the above embodiments, in the ring-shaped sub-area farther from the central area, the smaller the alignment angle of the first alignment film and the alignment angle of the second alignment film corresponding to the predetermined sub-pixel in the ring-shaped sub-area is, the better the alignment angle of the first alignment film and the alignment angle of the second alignment film corresponding to the other sub-pixels in the ring-shaped sub-area is, the larger the alignment angle is, the better the alignment angle is.
In a specific implementation, in the display panel provided in the embodiment of the present invention, the more the annular sub-regions included in the peripheral region, the smaller the overall chromaticity difference of the peripheral region, but the more difficult the manufacturing difficulty is, so that the maximum number of the annular sub-regions included in the peripheral region can be set to 7, which not only can ensure the overall chromaticity uniformity of the peripheral region, but also can reduce the manufacturing difficulty as much as possible.
Further, in practical implementation, in the display panel provided in the embodiment of the present invention, the alignment angles of the first alignment films corresponding to the sub-pixels except the predetermined sub-pixel in each annular sub-region are equal; or the alignment angles of the second alignment films corresponding to the sub-pixels except the preset sub-pixel in each annular sub-area are equal; or the alignment angles of the first alignment films corresponding to the sub-pixels except the preset sub-pixel in each annular sub-area are equal, and the alignment angles of the second alignment films corresponding to the sub-pixels except the preset sub-pixel in each annular sub-area are equal.
Preferably, in the display panel provided by the embodiment of the present invention, the alignment angle of the first alignment film and the alignment angle of the second alignment film corresponding to the same sub-pixel are equal.
Based on the same inventive concept, an embodiment of the present invention further provides a display device, as shown in fig. 4, including the display panel 1 provided in the embodiment of the present invention. The display device may be: any product or component with a display function, such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator and the like. The display device can be implemented by referring to the above embodiments of the display panel, and repeated descriptions are omitted.
In specific implementation, as shown in fig. 4, the display device provided in the embodiment of the present invention further includes a backlight module 2, where the backlight module 2 includes a backlight source and a quantum dot film, light emitted by the backlight source is in a first color, and taking the first color as blue as an example, the light in the blue excites quantum dots in the quantum dot film to generate green light and red light, and then the light in the three colors of red, green, and blue is mixed to form white light, and the white light enters the display panel. Therefore, by designing the display panel, the light transmittance corresponding to the sub-pixel of the first color in the peripheral area of the display panel is smaller than the light transmittance corresponding to the sub-pixels of other colors, so as to compensate the problem of color cast of the edge of the display panel caused by the fact that the light of the first color at the edge of the backlight module is more than the light of other colors.
In the display panel and the display device provided by the embodiment of the invention, the display panel is divided into the central area and the peripheral area surrounding the central area, and the peripheral area comprises at least one annular sub-area gradually extending from the edge of the display panel to the center of the display panel; in each annular sub-area, the alignment angle of the first alignment film corresponding to the preset sub-pixel is smaller than the alignment angles of the first alignment films corresponding to other sub-pixels except the preset sub-pixel; and/or the alignment angle of the second alignment film corresponding to the preset sub-pixel is smaller than the alignment angles of the second alignment films corresponding to other sub-pixels except the preset sub-pixel. Therefore, the light transmittance of the area corresponding to the preset sub-pixel is smaller than that of the areas corresponding to other sub-pixels, namely, the light transmittance of the first color in the annular sub-area is smaller than that of the other colors, so that the problem of color cast of the edge of the display panel caused by more light of a certain color than light of other colors at the edge of the backlight module can be compensated.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
