In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
An embodiment of the present invention provides a display device, where the display device may be: any product or component with a display function, such as electronic paper, a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame or a navigator, etc.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a display device according to an embodiment of the present invention. The display device may include: a display panel 10, and a grating structure 20 located at the light exit side of the display panel 10. In an embodiment of the present invention, the display panel 10 may be a liquid crystal display panel or an organic light emitting diode display panel, and when the display panel 10 is a liquid crystal display panel, the display device may further include: a backlight (not shown in fig. 1), and the display panel 10 is located between the grating structure 20 and the backlight.
The display panel 10 may include: a pixel layer 101. The pixel layer 101 may include: the first pixel group 101a and the second pixel group 101b are alternately arranged. In the embodiment of the present invention, each of the first pixel groups 101a and each of the second pixel groups 101b may include: at least one column of pixels, each column of pixels comprising: at least two colors of sub-pixels. By way of example, each pixel may include: red, green and blue sub-pixels.
The grating structure 20 may include: the opening regions 201 and the light-shielding regions 202 are alternately arranged. Note that the arrangement direction of the first pixel group 101a and the second pixel group 101b is parallel to the arrangement direction of the opening region 201 and the light-shielding region 202. Optionally, the display device may further include: the protective layer 30 is located on the grating structure 20, and the grating structure 20 in the display device can be protected by the protective layer 30, so that the peep-proof effect of the display device is prevented from being affected after the grating structure 20 is damaged.
In the embodiment of the present invention, the plurality of first pixel groups 101a are configured to display the target image. The plurality of second pixel groups 101b are configured to display an interference image different from the target image when the display apparatus is in the peep-proof display mode, and display the same shared image as the target image when the display apparatus is in the shared display mode. The interference image may be a solid color image (e.g., a black image).
Exemplarily, referring to fig. 2, fig. 2 is a schematic view of a visible region of the display device shown in fig. 1. After the light emitted from the first pixel group 101a in the display panel 10 passes through the grating structure 20, a first visible area 00a is formed on the light emitting side of the display device, and after the light emitted from the second pixel group 101b passes through the grating structure 20, a second visible area 00b is formed on the display device. When the user uses the display device, the user can view the image displayed by the first pixel group 101a and cannot view the image displayed by the second pixel group 101b when viewing the display device through the first viewing area 00 a; when the display device is viewed through the second viewing zone 00b, the screen displayed by the second pixel group 101b can be viewed, and the screen displayed by the first pixel group 101a cannot be viewed.

When the display device is in the peep-proof display mode, the first pixel groups display target images, and the second pixel groups display interference images different from the target images; when the display device is in the sharing display mode, the plurality of first pixel groups display the target image, and the plurality of second pixel groups display the same sharing image as the target image. Therefore, the display device can realize the peep-proof function and the sharing function, effectively enriches the display modes of the display device and improves the user experience.

The first pixel group 101a and the second pixel group 101b have the same width.
Referring to fig. 3 and 4, fig. 4 is a schematic view of a visible region of the display device shown in fig. 3. A first crosstalk area 00c is formed between the first visual area 00a and the second visual area 00b, and a second crosstalk area 00d is formed between the second visual area 00b and the light emitting side of the display device, so that a picture displayed by the display device cannot be viewed. It is assumed that the widths of the first pixel group 101a and the second pixel group 101b are both P; the effective refractive index of the medium between the grating structure 20 and the pixel layer 101 (i.e. the glass substrate 102) is n; the pitch between the grating structure 20 and the pixel layer 101 (i.e., the thickness of the glass substrate 102) is h; the width of each opening region 201 in the grating structure 20 is a; the distance between the first pixel group 101a and the second pixel group 101b (i.e. the width of the black matrix pattern 103) is m; the first visible region 00a has a visible angle of 2 × (pi/2-alpha)1) (ii) a The second visible region 00b has a viewing angle β1(ii) a The first crosstalk area 00c has a visible angle of (α)1－β1) (ii) a The second crosstalk area 00d has a viewing angle γ1。
In the embodiment of the invention, the display device can be known according to the law of refraction and the cosine lawThe parameters P, n, h, a, m, alpha in the center1、β1And gamma1The following formula is satisfied:
sin(π/2-α1)＝nsinα2 (1)
tanα2＝[(P-a)/2+m]/h＝(P-a+2m)/2h (2)
sin(π/2-β1)＝nsinβ2 (3)
tanβ2＝[P-(P-a)/2]/h＝(P+a)/2h (4)
sin(π/2-γ1)＝nsinγ2 (5)
tanγ2＝[P+m+P-(P-a)/2]/h＝(2P+2m+a)/2h (6)
it should be noted that, in the above 6 formulas, the parameters P, n and m are both definite values, and the parameters h and a are not definite values. The relation between the parameters h and a can be determined by the above 6 formulas, so that the sizes of h and a can be calculated. There are many realizations for determining the relationship between h and a, and the embodiment of the present invention is schematically illustrated by taking the following two realizations as examples:
in a first implementation, the following can be obtained according to equation (5) and equation (6):
in the embodiment of the present invention, the viewing angle γ of the second crosstalk area 00d1The smaller is cos gamma1The larger the value of (b), the better the display effect of the display device. Suppose that, in order to secure the display effect of the display device, γ needs to be secured1Satisfies the following conditions: gamma ray1≤γ1', then cos gamma1Need to satisfy cos γ1≥cosγ1'. In addition, cos γ1A, the following relationship can be obtained:
in addition, γ is1' belonging to the group of determined values,is generally determined according to the actual requirements of the display device to be manufactured later (e.g., the viewing angle of the second crosstalk area 00 d), and thus cos γ1' also belongs to the definite value. That is, a is a constant.
From equations (1) and (2) we can obtain:
from equations (3) and (4), we can obtain:
from equations (8) and (9), we can obtain:
in the embodiment of the present invention, the viewing angle (α) of the first crosstalk area 00c1－β1) The smaller, sin (. alpha.)1－β1) The smaller the value of (b), the better the display effect of the display device. Suppose that (α) needs to be ensured in order to ensure the display effect of the display device1－β1) Satisfies the following conditions: alpha is alpha1－β1≤(α1－β1) ', then sin (alpha)1－β1) Needs to satisfy sin (alpha)1－β1)≤sin(α1－β1)'. In addition, sin (α)1－β1) ' -B, the following relationship can be obtained:
in addition, (α)1－β1) ' is a determined value, and is generally determined according to the actual requirement (e.g., the visual angle of the first crosstalk area 00 c) of the display device to be prepared subsequentlyDefinitely, therefore, sin (α)1－β1) ' also belongs to the definite value. That is, B is a constant.
As can be seen from equations (9) and (10), the relationship between the parameters h and a satisfies the following relationship:
according to the relation between h and a, after the size of h is determined, the value range of a can be determined; after the value of a is determined, the value range of h can be determined.
In a second implementation, the following can be obtained according to formula (2) and formula (4):
from equations (1), (3) and (11) we can obtain:
from equations (1) and (2) we can obtain:
in the examples of the present invention, α1And beta1The determined value is generally determined according to the actual requirements of the display device to be manufactured later (for example, the visual angle of the first visual region 00a and the visual angle of the second visual region 00 b). Therefore, the magnitude of a can be calculated by equation (12). Then, the size of h can be calculated by the formula (13).
In combination with the first implementable manner and the second implementable manner, the following two exemplary implementable manners are listed:
in the first exampleIn an exemplary implementation manner, assuming that the width P of the first pixel group 101a and the second pixel group 101b is 147.4 micrometers, the pitch m of the first pixel group 101a and the second pixel group 101b is 9 micrometers, the effective refractive index of the medium between the grating structure 20 and the pixel layer 101 is 1.5, and the width a of each opening region 201 in the grating structure 20 is 40 micrometers, the size of the pitch h between the grating structure 20 and the pixel layer 101 and the viewing angle 2 × (pi/2- α) of the first viewing region 00a are 2 × (pi/2- α)1) Size of (2), and angle of visibility β of second visible area 00b1Size of (d), and angle of visibility γ of second crosstalk area 00d1And the viewing angle (alpha) of the first crosstalk area 00c1－β1) Refer to table 1 for the relationship between the sizes of (a).
TABLE 1
Illustratively, as can be seen from table 1, when h is 280 microns, 2 × (pi/2- α)1)＝28.29°，β1＝61.56°，γ1＝2.18°，α1－β1＝9.30°。
In the embodiment of the present invention, in order to improve the display effect of the display device, it is necessary to ensure the viewing angle γ of the second crosstalk area 00d1Smaller, and angle of visibility (α) of first crosstalk area 00c1－β1) As can be seen from table 1, if P is 147.4 micrometers, m is 9 micrometers, n is 1.5, and a is 40 micrometers, h should be ensured to be less than or equal to 280 millimeters. In addition, in order to improve the peep-proof effect of the display device, it is necessary to ensure the viewing angle 2 × (pi/2- α) of the first viewing zone 00a1) It cannot be too large, and it can be usually about 45 °, so assuming that P is 147.4 micrometers, m is 9 micrometers, n is 1.5, and a is 40 micrometers, it is necessary to ensure that h has a value in the range of [250, 280 °]And (3) micron.
In a second exemplary implementation manner, assuming that the width P of the first pixel group 101a and the second pixel group 101b is 147.4 micrometers, the pitch m of the first pixel group 101a and the second pixel group 101b is 9 micrometers, and the grating structure 20 and the second pixel group 101b are connected togetherThe effective refractive index of the medium between the pixel layers 101 is 1.5, the width a of each opening region 201 in the grating structure 20 is 80 micrometers, and the distance h between the grating structure 20 and the pixel layer 101 is 2 × (pi/2- α) from the first viewing area 00a1) Size of (2), and angle of visibility β of second visible area 00b1Size of (d), and angle of visibility γ of second crosstalk area 00d1And the viewing angle (alpha) of the first crosstalk area 00c1－β1) Refer to table 2 for the relationship between the sizes of (a) and (b).
TABLE 2
Similarly, if P is 147.4 micrometers, m is 9 micrometers, n is 1.5 micrometers, and a is 80 micrometers, it is necessary to ensure that h is less than or equal to 305 micrometers.
In summary, the display device provided in the embodiment of the invention includes: the display panel and the grating structure are positioned on the light emergent side of the display panel. When the display device is in the peep-proof display mode, the first pixel groups display target images, and the second pixel groups display interference images different from the target images; when the display device is in the sharing display mode, the plurality of first pixel groups display the target image, and the plurality of second pixel groups display the same sharing image as the target image. Therefore, the display device can realize the peep-proof function and the sharing function, effectively enriches the display modes of the display device and improves the user experience.

In summary, in the display method provided in the embodiment of the present invention, when the display device is in the peep-proof display mode, the plurality of first pixel groups are controlled to display the target image, and the plurality of second pixel groups are controlled to display the interference image different from the target image; when the display device is in a sharing display mode, the plurality of first pixel groups are controlled to display the target image, and the plurality of second pixel groups are controlled to display the same sharing image as the target image. Therefore, the display device can realize the peep-proof function and the sharing function, effectively enriches the display modes of the display device and improves the user experience.
Referring to fig. 6, fig. 6 is a flowchart of another display method according to an embodiment of the invention. The method is applied to the display device shown in fig. 1 or fig. 2. The display method may include:
In the embodiment of the invention, the display device is provided with the first button which is used for triggering the display device to be in the peep-proof display mode, and after a user triggers the first button, the display device can receive a signal for indicating that the display device is in the peep-proof display mode. At this time, the display device may convert the initial image into the target image.
It should be noted that the initial image is an image that the display panel needs to display, and the resolution of the initial image is the same as the resolution of the display panel, that is, both the first pixel group and the second pixel group in the display panel can display the initial image. When the display device needs to perform peep-proof display, the display device needs to convert the initial image into the target image, and in order not to affect the display effect of the display device, it is necessary to ensure that the displayed content of the target image is consistent with the displayed content of the initial image, and at this time, the resolution of the target image is half of the resolution of the initial image. For example, assuming that the resolution of the initial image is 500 × 500, the resolution of the target image is 500 × 250.
In an embodiment of the present invention, the display device may generate the first image based on the target image such that the first image includes the target image and the interference image. The interference image may be a different image than the target image. By way of example, the interference image may be a solid image, for example, it may be a black image.
In the embodiment of the invention, the display device can control the display panel to display the first image, so that the first pixel groups display the target image and the second pixel groups display the interference image, thereby realizing the peep-proof function.
