Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a schematic flow chart diagram illustrating a display control method according to an embodiment of the present disclosure. The display control method disclosed by the embodiment of the disclosure can be applied to a terminal, the terminal can be an electronic device including a display panel and an image acquisition device, such as a mobile phone, a tablet computer, a personal computer, and the like, and the image acquisition device can be a front camera of the terminal.
The image acquisition device is disposed on one side of the display panel (for example, below the display panel), and the display panel may be an Organic Light-Emitting Diode (OLED) display panel.
As shown in fig. 1, the display control method may include the steps of:
in step S1, upon receiving a control instruction for controlling the image capturing apparatus, determining whether the control instruction has been authorized;
in step S2, if the control command is not authorized and the display panel does not display an image, the display panel is controlled to display an image.
In one embodiment, if a control instruction for controlling the image capturing apparatus is not authorized, it may be determined that the control instruction is not an instruction input by a user of the terminal, and the image capturing apparatus may capture an image based on the control instruction, which may cause privacy of the user to be revealed.
Under this situation, the embodiment of the present disclosure can control the display panel on the image acquisition device to display images, because the display panel is located on the image acquisition device, that is, the light acquired by the image acquisition device needs to pass through the display panel, so that the image displayed by the image acquisition device can be acquired by the image acquisition device by controlling the display panel to display images, thereby causing interference to the image acquisition device, and being beneficial to avoiding privacy disclosure of users.
And under the condition that the display panel does not display the image, the display panel is controlled to display the image, for example, characters can be displayed, and the user is prompted to receive an unauthorized control instruction by the image acquisition equipment through the characters, so that the user can be noticed to the change of the display panel, the effect of reminding the user is achieved, the user can be noticed to the fact that the image acquisition equipment receives the unauthorized control instruction in time, and then corresponding measures are taken.
Fig. 2 is a schematic flow chart diagram illustrating another display control method according to an embodiment of the present disclosure. As shown in fig. 2, on the basis of the embodiment shown in fig. 1, the display panel includes a first display region and a second display region, and the transmittance of the first display region is greater than that of the second display region; wherein the controlling the display panel to display an image includes:
in step S21, the first display region is controlled to display an image.
In one embodiment, due to the low transmittance of current display panels, it is difficult to capture images through the display panel when the image capture device is located below the display panel. In order to improve the transmittance, the structure of the display panel may be adjusted, for example, the number of pixels in a unit area is reduced, signal lines required to be connected to the pixels are reduced, and details about the adjustment of the structure of the display panel are described in the following embodiments.
However, the adjustment of the structure of the display panel can improve the transmittance of the display panel, but the display effect of the display panel is reduced. According to an embodiment of the present disclosure, a display panel may be divided into two regions: the display device comprises a first display area and a second display area, wherein the transmittance of the first display area is greater than that of the second display area, so that the transmittance can be improved by only adjusting the structure in the first display area, and the structure of the second display area does not need to be adjusted, so that the second display area has a good display effect.
Based on the above structure, the image pickup device can be disposed below the first display region, and although the transmittance of the second display region is low, the image pickup device is not affected. When the image acquisition equipment is determined to receive an unauthorized control instruction, the image acquisition equipment can only be controlled to display the image in the first display area in the display panel, so that the effects of interfering the image acquisition equipment and prompting a user can be achieved, and the image does not need to be displayed in the second display area, so that the power consumption can be reduced.
Fig. 3 is a schematic flowchart illustrating still another display control method according to an embodiment of the present disclosure. As shown in fig. 3, based on the embodiment shown in fig. 2, the display parameters of the first display area are the same as the display parameters of the second display area, and the method further includes:
in step S3, if the control command is not authorized and the display panel is displaying images, the display parameters of the first display area are adjusted to be different from the display parameters of the second display area.
In one embodiment, since the sufficient filtering of the first display region is high, even if the first display region is displaying an image, the image capture device located below the first display region can capture an image of the front face of the terminal to some extent through the first display region.
Therefore, under the condition that the display panel is displaying an image, if it is determined that the image acquisition device receives an unauthorized control instruction, the user also needs to be prompted in time, so that the user can notice that the image acquisition device receives the unauthorized control instruction in time, and further take corresponding measures.
According to the embodiment of the disclosure, in order to ensure that the first display area and the second display area have a relatively balanced display effect, the display parameters of the first display area may be set to be the same as the display parameters of the second display area, and when it is determined that the image capture device receives an unauthorized control instruction, the display parameters of the first display area may be adjusted to be different from the display parameters of the second display area.
For example, the brightness of the first display region is adjusted to be different from the brightness of the second display region, for example, the contrast of the first display region is adjusted to be different from the contrast of the second display region, for example, the display frequency of the first display region is adjusted to be different from the display frequency of the second display region.
Therefore, the user can be timely reminded of paying attention to the fact that the image acquisition equipment receives an unauthorized control instruction, and then corresponding measures are taken, the user can still be guaranteed to watch the image displayed by the display panel, and watching experience is guaranteed.
Fig. 4 is a schematic flowchart illustrating still another display control method according to an embodiment of the present disclosure. As shown in fig. 4, based on the embodiment shown in fig. 3, the area of the first display region is smaller than the area of the second display region, and the adjusting the display parameter of the first display region is different from the display parameter of the second display region includes:
in step S31, the luminance of the first display region is increased so that the luminance of the first display region is higher than the luminance of the second display region.
In an embodiment, since the image capturing device is generally smaller in size, the area of the first display region disposed thereon may also be set smaller, for example, smaller than the area of the second display region, in this case, the first display region with a poor display effect may have a smaller area than the second display region with a good display effect, so as to ensure that the display panel has a better display effect as a whole.
And then when the display parameters of the first display area are adjusted to be different from those of the second display area, the brightness of the first display area can be improved to enable the brightness of the first display area to be higher than that of the second display area, so that on one hand, the brightness of the second display area does not need to be adjusted to enable the display parameters of the second display area of the main part of the display image to be unchanged, and only the display parameters of the first display area of the non-main part of the display image are changed to reduce the influence on the viewing effect of the user, and on the other hand, by improving the brightness of the first display area, a striking prompt effect can be achieved, so that the user can timely notice that the image acquisition equipment receives an unauthorized control instruction, and further take corresponding measures.
The adjustment of the structure in the display panel by the present disclosure is exemplarily described below by several embodiments.
In one embodiment, the sub-pixels in the pixel unit in the display panel are arranged in a matrix along a row direction and a column direction, and the distance between each sub-pixel in the sub-pixels in the same row in the column direction is 0, and the distance between each sub-pixel in the sub-pixels in the same column in the row direction is 0.
The structure can enable a slit which is obvious along the row direction to exist between sub-pixels of adjacent rows and a slit which is obvious along the column direction to exist between sub-pixels of adjacent columns, light can be diffracted when passing through the slits, the more neat the boundary of the slits, the stronger the diffraction effect is, and even the condition that light rays passing through the two slits are interfered can exist, and the more neat the boundary of the slits, the stronger the interference effect is.
Because image acquisition equipment is arranged below the first display area, if strong diffraction and interference phenomena occur to light passing through the first display area, obvious light and dark alternate stripes can be formed, and therefore the image acquired by the image acquisition equipment has the obvious light and dark alternate stripes, and the shooting effect is influenced.
According to an embodiment of the present disclosure, the organic light emitting diode display panel includes a plurality of pixel units, each pixel unit including a plurality of sub-pixels distributed along a row direction and a column direction;
and the distance between adjacent sub-pixels in the sub-pixels of the same row in the column direction is greater than 0, and/or the distance between adjacent sub-pixels in the sub-pixels of the same column in the row direction is greater than 0.
Based on the embodiment of the disclosure, by setting the distance between at least one sub-pixel in the sub-pixels of the same row and other sub-pixels in the column direction to be greater than 0, the slit boundaries in the row direction between the sub-pixels of adjacent rows can be irregular, so that the interference effect generated by the slits in the row direction is reduced. Similarly, by setting the distance between at least one sub-pixel in the sub-pixels in the same column and other sub-pixels in the row direction to be greater than 0, the slit boundaries in the column direction between the sub-pixels in adjacent columns can be irregular, thereby reducing the interference effect generated by the slits in the column direction. And then avoid the light through first display area to take place stronger diffraction or interference phenomenon to guarantee under the first display area in the image that image acquisition equipment gathered can not have comparatively obvious alternate stripe of light and shade, be favorable to guaranteeing good shooting effect.
Next, taking the slit in the row direction as an example, the related art and the embodiment of the present disclosure are compared with each other by fig. 5 and 6.
Fig. 5 is a schematic diagram showing an arrangement of sub-pixels based on the related art. Fig. 6 is a schematic diagram illustrating an arrangement of sub-pixels in a first display region according to an embodiment of the disclosure.
As shown in fig. 5 and 6, the pixel unit includes a red sub-pixel, a green sub-pixel, and a blue sub-pixel.
In fig. 5, the distance in the column direction of all the sub-pixels in the red sub-pixels of the same row is equal to 0, and the distance in the column direction of all the sub-pixels in the green sub-pixels of the same row is equal to 0, which makes the boundaries of the slits in the row direction formed between the red sub-pixels and the green sub-pixels of the same row well-ordered.
In fig. 6, the distance between adjacent sub-pixels in the red sub-pixels of the same row in the column direction is greater than 0, and the distance between adjacent sub-pixels in the green sub-pixels of the same column in the row direction is greater than 0, which makes the boundaries of the slits in the row direction formed between the red sub-pixels of one row and the green sub-pixels of one row irregular.
Compared with the slit shown in fig. 5, the light has weaker diffraction and diffraction effects through the slit in fig. 6, and the arrangement mode of the sub-pixels in the first display area is set based on the embodiment, so that the phenomenon of stronger diffraction or interference of the light passing through the first display area can be avoided, and therefore, the situation that the image collected by the image collecting device under the first display area has more obvious light and dark alternate stripes is avoided, and the good shooting effect is favorably ensured.
In one embodiment, the distance between adjacent sub-pixels in the sub-pixels of the same row in the column direction is greater than 0, and/or the distance between adjacent sub-pixels in the sub-pixels of the same column in the row direction is greater than 0. Therefore, the distance between the largest number of sub-pixels in the same row and other sub-pixels in the column direction is larger than 0, so that slit boundaries between the sub-pixels in adjacent rows in the row direction are irregular to a greater extent, and slit boundaries between the sub-pixels in adjacent columns in the column direction are irregular to a greater extent, and the phenomenon that light rays passing through the first display area are subjected to stronger diffraction or interference is favorably reduced.
Fig. 7 is a schematic diagram illustrating an arrangement of sub-pixels in the first display region according to an embodiment of the present disclosure.
In one embodiment, as shown in fig. 7, the distance between adjacent sub-pixels in the column direction is d1, and the distance between adjacent sub-pixels in the row direction in the column direction is d1
d1/2。
According to the arrangement, the distance of the adjacent sub-pixels in the same row in the column direction can be ensured to be the largest, so that the slit boundaries between the sub-pixels in the adjacent rows along the row direction are irregular to the greatest extent, and the phenomenon of strong diffraction or interference of light passing through the first display area is favorably reduced.
Fig. 8 is a schematic diagram illustrating an arrangement of sub-pixels in a first display region according to an embodiment of the present disclosure.
In one embodiment, as shown in fig. 8, the distance between adjacent sub-pixels in the row direction is d2, and the distance between adjacent sub-pixels in the column direction is d 2/2.
According to the arrangement, the distance between the adjacent sub-pixels in the same column of sub-pixels in the column direction can be ensured to be the largest, so that the slit boundaries between the sub-pixels in the adjacent columns in the column direction are irregular to the greatest extent, and the phenomenon of strong diffraction or interference of light passing through the first display area is favorably reduced.
In one embodiment, the signal lines of the sub-pixels of the same color are the same signal line.
Because the image acquisition device is arranged below the first display area, when the image acquisition device acquires an image, the image on the front side of the terminal needs to be acquired through the first display area, but it needs to be ensured that the first display area has a display function, which needs to ensure that the first display area has a higher transmittance on the basis of having the display function, and at least the transmittance is higher than that of the second display area.
According to the embodiment, for the sub-pixels in the first display region, the signal lines of the sub-pixels of the same color may be set to be the same signal line, wherein the signal line includes at least one of:
a scan line, a signal line, and a driving current transmission line (i.e., a line connected to VDD for transmitting a current to the organic light emitting diode through the driving transistor).
For example, taking a scan line as an example, all red sub-pixels in the first display region are connected to one scan line, all green sub-pixels in the first display region are connected to one scan line, and all blue sub-pixels in the first display region are connected to one scan line, so that the first display region still has a certain display function, and the scan lines in the first display region are reduced to a great extent, thereby reducing the shielding of the scan lines on light, effectively improving the transmittance of the first display region, and ensuring that the image acquisition device below the first display region can acquire clear images.
In addition, a signal line may be provided based on the embodiment shown in fig. 7 or fig. 8. Taking the scan line as an example, in order to connect all the red subpixels to one scan line, the red subpixels in the same row may be connected, and then one line is led out from each row of red subpixels to be connected to one scan line, and based on the embodiment shown in fig. 5 or fig. 6, the distribution of the subpixels has strong regularity, so that the connection lines between the subpixels have strong regularity, which is beneficial to simplifying the patterning process for forming the connection lines.
In one embodiment, the sub-pixels of the same color in the pixel units in the same row are located in the same row, and the signal lines of the sub-pixels of the same color in the same row are the same signal line. The sub-pixels in the first display area can be controlled to be turned on and off in line granularity by controlling a line of sub-pixels with the same color through a signal line, and the display capacity of the first display area is improved compared with the situation that the sub-pixels with all colors are connected to a signal box.
In one embodiment, the sub-pixels with the same color in the pixel units of the same column are located in the same column, and the signal lines of the sub-pixels with the same color in the same column are the same signal line. A column of sub-pixels with the same color can be controlled by one signal line, so that the sub-pixels in the first display area can be controlled to be turned on and off in a column granularity, and the display capability of the first display area is improved compared with the situation that the sub-pixels with all colors are connected to one signal box.
In one embodiment, the first display region includes a plurality of sub-regions, wherein signal lines of sub-pixels of the same color in different sub-regions are different signal lines. Therefore, the sub-pixels with the same color in one sub-area can be controlled to be turned on or turned off through one signal line, namely, the granularity displayed by the first display area is the sub-area, and the display capacity of the first display area is improved compared with the situation that the sub-pixels with all colors are connected to one signal box.
