Specifically, the display panel generally includes a first polarizer close to the backlight source and a second polarizer far from the backlight source, and the polarization direction of the first polarizer is perpendicular to the polarization direction of the second polarizer. When the confidentiality of the display panel is realized, the display panel only comprises the first polarizer, when a user watches confidential images, the user can wear polarizer glasses with the polarization direction identical to that of the second polarizer, at the moment, light emitted by a backlight source of the display panel reaches human eyes after passing through the first polarizer and the polarizer glasses (equivalent to the second polarizer), and the user can see the confidential images. When the user does not wear the polaroid glasses, the light emitted by the backlight source of the display panel reaches the human eyes only after passing through the first polaroid, and at the moment, the display panel displays a full white picture, namely, the user who does not wear the polaroid glasses cannot see the confidential image, so that the user who does not wear the polaroid glasses is prevented from peeping the confidential image.

Fig. 2-1 is a flowchart of another method for controlling a display according to another embodiment of the present invention, where the method for controlling a display panel may be used to control the display panel, and the display panel may include n pixels arranged in an array, where n is a positive integer, where each pixel may include: as shown in fig. 2-1, the display control method includes:
Specifically, the display control method provided by the embodiment of the present invention may be applied to a display control device, that is, the display control device may be used to control a display panel to display an image, and the display control device and the display panel may form a display device. The user may send a data display instruction to the display control device according to his or her own needs (e.g., the user presses a specific button on the display control device, or selects one of the secure mode option and the non-secure mode option displayed on the display panel), and the data display instruction may be used to indicate whether the current display mode is the secure mode or the non-secure mode.
After receiving the data display instruction, the display control device can determine the current display mode according to the data display instruction and judge whether the current display mode is the secret mode.
Further, the data display instruction can be used to indicate the data to be displayed, and the data to be displayed is the secret data. When the current display mode indicated by the data display instruction is the secret mode, the display control means may determine the data indicated by the data display instruction as secret data.
And step 204, acquiring preset data as non-confidential data. Step 205 is performed.
Optionally, the display control device may store preset data in advance, and when it is determined that the current display mode is the secret mode, the display control device may determine that the preset data is non-secret data. Optionally, the data display instruction may also be used to indicate non-secure data that needs to be displayed, and in step 204, the display control device may use the non-secure data indicated by the data display instruction as the non-secure data.
Specifically, after the confidential data and the non-confidential data are determined, the display control device may control, according to the confidential data, the region where the n first subpixels in the display panel are located to display the first image corresponding to the confidential data, and control, according to the non-confidential data, the region where the n second subpixels in the display panel are located to display the second image corresponding to the non-confidential data, and since the filter glasses may filter out light of the first apparent sensitivity emitted by the first subpixels, a wearer of the filter glasses may see the first image displayed in the region where the n first subpixels are located on the display panel.
For example, the specific visual perception of light is the visual contrast sensitivity (english) of light, which can reflect the sensitivity of human eyes to light, and is due to: the luminous flux (unit: lumen) × 683 (unit: lumen per watt) of the luminous flux of the monochromatic light × energy (unit: watt) of the radiation beam of the monochromatic light, that is, the luminous flux of a monochromatic light seen by human eyes is proportional to the specific visual sensitivity of the light, and the higher the specific visual sensitivity of the light, the higher the luminous flux of the light, the stronger the radiation power of the light perceived by the human eyes. Since the specific visibility of the light emitted by the first sub-pixel is smaller than that of the light emitted by the second sub-pixel, the radiation power of the light emitted by the first sub-pixel that can be perceived by the human eye is larger than that of the light emitted by the second sub-pixel, and the human eye can clearly see the light emitted by the first sub-pixel but cannot see (or cannot see clearly) the light emitted by the second sub-pixel.
When the plurality of first sub-pixels on the display panel display the first image, and the plurality of second sub-pixels on the display panel display the second image, other users who do not wear the filter glasses can clearly see the second image but cannot see (or cannot see) the second image, and the user who wears the filter glasses can only see the first image, so that the first image is effectively hidden, the confidentiality of the display panel is realized, and the user who does not wear the filter glasses can see the second image on the display screen while watching the first image, and the flexibility of the display panel for displaying the image is improved.
Fig. 2-2 is a schematic diagram of a corresponding relationship between a wavelength and a contrast sensitivity according to an embodiment of the present invention, and it can be known from fig. 2-2 that: the specific sensitivity of green light having a wavelength of 546.1 nm, the specific sensitivity of blue light having a wavelength of 435.8 nm, and the specific sensitivity of red light having a wavelength of 700 nm were decreased in this order, and the difference between the specific sensitivity of green light having a wavelength of 546.1 nm and the specific sensitivity of red light having a wavelength of 700 nm was large. When the specific sensitivity of green light with a wavelength of 546.1 nm is 1, the specific sensitivity of red light with a wavelength of 700 nm is 0.004, the specific sensitivity of blue light with a wavelength of 435.8 nm is 0.038, that is, the intensity of 1000 blue light photons with a wavelength of 450 nm entering human eyes is equivalent to the intensity of 38 green light photons with a wavelength of 555 nm entering human eyes, the intensity of 1000 red light photons with a wavelength of 700 nm entering human eyes is equivalent to the intensity of 4 green light photons with a wavelength of 555 nm.
On one hand, because the specific visibility of the green light is far greater than that of the red light, the first sub-pixel may be a red sub-pixel, the red sub-pixel may emit red light, the wavelength of the red light may be 700 nm, the second sub-pixel may be a green sub-pixel, the green sub-pixel may emit green light, the wavelength of the green light may be 546.1 nm, and the filter glasses may be configured to filter out the red light. Optionally, each pixel may also include a blue sub-pixel. That is, as shown in fig. 3, each pixel 01 on the display panel may include: the red subpixel 011, the green subpixel 012, and the blue subpixel 013, and the red subpixel 011, the green subpixel 012, and the blue subpixel 013 are arranged in this order along the gate line scanning direction x. The first image is composed of red light emitted by the plurality of red sub-pixels 011, that is, the first image is a red image, the second image is composed of green light emitted by the plurality of green sub-pixels 012, that is, the second image is a green image, a wearer of the filter glasses can see the red first image and cannot see the green second image, and a user who does not wear the filter glasses can see the green second image and cannot see (or cannot see clearly) the red first image. Alternatively, at this time, an image may be displayed without controlling a region corresponding to the blue subpixel 013 on the display panel.
On the other hand, since the specific visibility of green is much greater than that of blue, the first sub-pixel may be a blue sub-pixel, the blue sub-pixel may emit blue light, the wavelength of the blue light may be 435.8 nm, the second sub-pixel may be a green sub-pixel, the green sub-pixel may emit green light, the wavelength of the green light may be 546.1 nm, and the filter glasses may be used to filter out the blue light. Optionally, each pixel may also include a red sub-pixel. That is, as shown in fig. 3, each pixel 01 on the display panel may include: the red subpixel 011, the green subpixel 012, and the blue subpixel 013, and the blue subpixel 011, the green subpixel 012, and the blue subpixel 013 are arranged in this order along the gate line scanning direction x. The first image is composed of blue light emitted by the plurality of blue sub-pixels 013, that is, the first image is a blue image, the second image is composed of green light emitted by the plurality of green sub-pixels 012, that is, the second image is a green image, a wearer of the filter glasses can see the blue first image and cannot see the green second image, and a user who does not wear the filter glasses can see the green second image and cannot see (or cannot see clearly) the blue first image. Optionally, at this time, it is not necessary to control the region corresponding to the red sub-pixel 011 on the display panel to display an image.
For example, in order to further enhance the intensity of the first image perceived by the human eye and reduce the intensity of the second image perceived by the human eye, in the process of controlling the regions corresponding to the n first sub-pixels on the display panel to display the first image and controlling the regions corresponding to the n second sub-pixels on the display panel to display the second image, the brightness of the first image may be controlled to be smaller than that of the second image. Because the brightness of the first image is less than that of the second image, the attention of a user who does not wear the color filter glasses to the second image can be improved, the attention of the user to the first image is further reduced, and the first image is further hidden.
Specifically, the brightness of the light may correspond to 256 gray-scale values (gray-scale value 0 to gray-scale value 255), and when the brightness of the first image and the second image is adjusted, the brightness of the light emitted by all the first sub-pixels may be adjusted to the brightness corresponding to the gray-scale value 110, so that the brightness of the first image corresponds to the gray-scale value 110; the brightness of the light emitted by all the second sub-pixels is adjusted to the brightness corresponding to the gray-scale value 200, so that the brightness of the second image corresponds to the gray-scale value 200. Then, the brightness of the light emitted by each first sub-pixel and the brightness of the light emitted by each second sub-pixel may be adjusted to change the difference between the brightness of the light emitted by the first sub-pixel and the brightness of the light emitted by the second sub-pixel until the first image is not visible to a user who is not wearing color filter glasses and the first image is visible to a user who is wearing color filter glasses.
And step 206, determining the data indicated by the data display instruction as target data. Step 207 is performed.
When the current display mode is the non-secure mode, the data display instruction may be used to indicate data that needs to be displayed, and at this time, the data that needs to be displayed is non-secure data, and the display control apparatus may determine the data indicated by the data display instruction as target data.
And step 207, controlling the effective display area in the display panel to display a third image corresponding to the target data.
After the target data is determined, the display control device may further control an effective display area (including an area corresponding to all sub-pixels in the display panel) in the display panel to display a third image corresponding to the target data according to the target data, and a specific step of controlling the display panel to display the third image may refer to related technologies, which is not described herein again in this embodiment of the present invention.
Since the display panel with privacy in the related art includes only one polarizer, only a user wearing the polarizer glasses can see a privacy image displayed by the display panel. When the confidentiality of the display panel is not needed, namely when the display panel is controlled to display normally, a user also needs to wear the polaroid glasses to see an image. In the embodiment of the invention, before displaying the image, the current display mode is judged to be the secret mode or the non-secret mode, when the current mode is the secret mode, the secret of the display panel is realized, and when the current mode is the non-secret mode, the display panel can still be controlled to normally display, namely when the current mode is the non-secret mode, all users can see the image displayed on the display panel without wearing glasses.
In the related art, the display screen In modes such as Advanced Super Dimension Switch (ADS), In Plane Switch (IPS), Multi-domain Vertical Alignment (MVA) has a relatively wide viewing angle, so that other users around the display screen can see the image displayed on the display screen, and thus the display screen has poor security. In the related art, the privacy of the display screen can be realized by designing one polarizer in the display panel as polarizer glasses, but when a user wears the polarizer glasses to watch a confidential image on the display screen, the display screen actually shows a white screen, and other users around the display screen feel that the user wears the glasses to watch the white screen in front of the display screen, so that the user feels strange and has a feeling of masking ears and stealing bells. In the embodiment of the invention, when a user wears color filter glasses to watch a confidential image (a first image) on the display screen, other users watch a non-confidential image (a second image) on the display screen by wearing the glasses, so that the user does not feel that the user can disguise the earring. In addition, in the related art, data processing can be performed based on an FPR (imaging mode of a new generation of 3D television) screen to realize the confidentiality of the display screen, but the production cost of the FPR screen is high, so that the display control method is not practical, and in the embodiment of the invention, the confidentiality of the display panel can be realized based on a common display panel, and the display control method is high in practicability.
In summary, in the display control method provided by the embodiment of the invention, after the secure data and the non-secure data are acquired, the area of the first sub-pixel in the display panel can be controlled to display the first image corresponding to the security data, and controlling the area of the second sub-pixel in the display panel to display a second image corresponding to the non-confidential data, and because the filter glasses are used for filtering the light with the first visual sensitivity, the wearer of the filter glasses can see the first image, and at the moment, because the specific visibility of the light emitted by the second sub-pixel is larger than that of the light emitted by the first sub-pixel, the user who does not wear the filter glasses can see the second image, and the eyes of the user who does not wear the filter glasses directly ignore the first image, the confidentiality of the display panel is realized, and the flexibility of the display panel for displaying the image is improved.
