Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus consistent with some aspects of the present application as detailed in the accompanying claims.
On intelligent electronic devices such as mobile phones and tablet computers, due to the need to integrate photosensitive devices such as front cameras and light sensors, the photosensitive devices can be arranged below the transparent display area in a manner of arranging the transparent display area on the electronic devices, so that the full-screen display of the electronic devices can be realized under the condition that the normal operation of the photosensitive devices is ensured.
When the camera is started, the transparent display area does not display, light can enter the camera through the transparent display area, and the camera receives incident light and generates image data. The non-transparent display area displays an image corresponding to the image data according to the image data. Generally, in order to ensure the imaging quality of the camera, more light can enter the camera through the transparent display area, and the transparent display area should cover the visual field of the camera. The inventor finds that, due to the process deviation, the area of the transparent display area is generally larger than the area of the area corresponding to the light incident side of the transparent display area in the visual field range of the camera, so that the area of the non-transparent display area is smaller, and the area of the display panel for displaying images is smaller.
In order to solve the above problems, embodiments of the present application provide a display control method of a display device and a display device, which can well solve the above problems. The following describes a display control method and a display device of a display panel in an embodiment of the present application in detail with reference to the accompanying drawings.

The display control method of the display device is used for controlling display of the display panel of the display device. Referring to fig. 1 and 2, a display apparatus 100 includes a display panel 10 and an image pickup device 20. The display panel 10 includes a first display area 101 and a second display area 102, the light transmittance of the first display area 101 is greater than the light transmittance of the second display area 102, and the image capturing device 20 is located below the display panel 10 and opposite to the first display area 101.

In one embodiment, the display apparatus 100 may further include a light sensor, such as a distance sensor, disposed under the display panel 10 opposite the first display area 101, and ambient light may enter the light sensor through the first display area 101.
Since the light transmittance of the display substrate 101 located in the first display area 101 is greater than that of the display substrate 101 located in the second display area 102, a photosensitive device can be arranged below the first display area 101, so that the photosensitive device can collect or emit light through the first display area 101, and the full-screen display of the display panel can be realized on the premise that the camera works normally.
In one embodiment, the display device may include a controller, and the display control method of the display device may be used for the controller, that is, the controller performs the display control method of the display device.

Fig. 3 is a flowchart of a display control method of a display device according to an embodiment of the present application. Referring to fig. 3, the display control method includes the following steps 110 to 130. The details will be described below.
In step 110, it is detected whether the image pickup device is on.
In one embodiment, the controller may determine that the image pickup device is turned on when detecting an on command of the image pickup device. The display device generates an opening instruction according to the touch screen operation or the key operation of the user. The controller can acquire the opening instruction in real time, and when the controller acquires the opening instruction, the camera device can be determined to be opened.
In step 120, when it is detected that the image capturing apparatus is turned on, position information of a light transmitting area of the first display area is determined, and the area of the first display area is larger than that of the light transmitting area.
The light-transmitting region 103 of the first display area 101 refers to a region through which light passes when entering the image capturing apparatus 20. In this step, determining the light transmitting area of the first display area refers to determining the size and position of the light transmitting area.
In one embodiment, referring to fig. 4, the determining the position information of the light transmitting area of the first display area may be implemented by the following steps 121 to 123.
In step 121, a first distance between the light entrance side of the display panel facing away from the image capturing device and the image capturing device is determined.
At the time of imaging, the image pickup device 10 allows light to enter the display panel 10 from the light incident side 11 of the display panel 10, then to pass through the display panel 10, and to enter the image pickup device 20.
In one embodiment, referring again to fig. 1, the display apparatus 100 may further include a distance detecting device 30, where the distance detecting device 30 is disposed on a side of the display panel 10 near the image capturing device 20 and opposite to the first display area 101. The distance detecting device 30 may be made of a transparent material, and light emitted from the display panel 10 may pass through the distance detecting device 30 and then enter the image pickup device 20.
Referring to fig. 5, the step 121 of determining the first distance between the light incident side of the display panel facing away from the image capturing apparatus and the image capturing apparatus may be implemented by the following steps 1211 to 1213.
In step 1211, a second distance between the image capturing device and the distance detecting device is determined.
The second distance d2 between the image pickup device 20 and the distance detection device 30 refers to a distance between the image pickup device 20 and a side of the distance detection device 30 that is close to the image pickup device 20.
In one embodiment, the distance detecting means 30 may include an infrared sensor, and the image pickup means 20 may emit infrared rays. The step 1211 of determining the second distance between the image pickup device and the infrared sensor may be implemented by the following steps 1201 and 1202.
In step 1201, the intensity of the infrared rays received by the infrared sensor and the intensity of the infrared rays emitted by the image pickup device are collected.
In one embodiment, the camera device 20 may be provided with an infrared emitter. The camera device 20 can emit infrared rays after being turned on. The infrared sensor receives the infrared rays emitted from the image pickup device 20, and can detect the intensity of the received infrared rays. The infrared sensor and the controller can transmit signals, and the controller can collect the intensity of the received infrared rays detected by the infrared sensor.
The intensity of the infrared rays emitted from the image pickup device 20 may be a constant value, and the intensity of the infrared rays emitted from the image pickup device 20 may be stored in advance in the storage device of the display apparatus 100. In this step, the controller may directly acquire the intensity of the infrared rays emitted from the image pickup device 20 from the storage device. Alternatively, the image pickup device 20 may be provided with an infrared sensor for detecting the intensity of the infrared rays emitted from the image pickup device 20, the image pickup device 20 is in signal connection with a controller, and the controller may collect the intensity of the infrared rays detected by the infrared sensor of the image pickup device 20.
In step 1202, the second distance is determined according to the intensity of the infrared ray received by the infrared sensor and the intensity of the infrared ray emitted by the image capturing device.
A portion of the energy is lost during the transmission of the infrared light from the camera 20 to the infrared sensor, and the intensity of the infrared light received by the infrared sensor is less than the intensity of the infrared light emitted by the camera 20. The greater the distance between the image pickup device 20 and the infrared sensor, the greater the energy lost by the infrared rays during transmission, and thus, the second distance d2 between the infrared sensor and the image pickup device 20 can be determined using the intensity of the infrared rays received by the infrared sensor and the intensity of the infrared rays emitted by the image pickup device 20.
In an exemplary embodiment, there is a correspondence between the intensity of the infrared ray loss and the second distance d2, and the controller may calculate the intensity of the infrared ray loss according to the intensity of the infrared ray received by the infrared sensor and the intensity of the infrared ray emitted by the image capturing device 20, and determine the second distance d2 between the infrared sensor and the image capturing device 20 according to the correspondence between the intensity of the infrared ray loss and the intensity of the infrared ray.
In other embodiments, the distance sensing device 30 may be other types of sensors, such as a laser distance sensor, or the like.
In step 1212, a first thickness of the distance detection device and a second thickness of the display panel are obtained.
In one embodiment, the first thickness of the distance detecting means 30 and the second thickness of the display panel 10 may be measured during the manufacturing of the display apparatus 100 and stored in the storage means of the display apparatus in advance. The controller may directly obtain the first thickness d3 of the distance detecting device 30 and the second thickness d4 of the display panel 10 from the storage device.
In step 1213, the first distance is determined based on the second distance, the first thickness, and the second thickness.
In one embodiment, the second distance d2 between the infrared sensor and the image capturing device 20, the first thickness d3 of the distance detecting device 30, and the second thickness d4 of the display panel 10 are added to obtain the first distance d1 between the image capturing device 20 and the light incident side of the display panel 10.
In step 122, the angle of view of the imaging device and the positional information of the center of the light-transmitting region are acquired.
The field angle of the image capturing device 20 refers to an angle formed by two edges of the maximum range of the lens, which is formed by taking the lens of the image capturing device 20 as the vertex and allowing the object image of the measured object to pass through. The twice the maximum angle of incidence of the light rays incident on the image pickup device 20 is equal to the angle of view of the image pickup device 20. In one embodiment, the view angle θ of the image pickup device 20 may be stored in the storage device of the display apparatus 100 in advance, and the controller may directly acquire the view angle θ of the image pickup device 20 from the storage device.
The center of the light-transmitting region 103 is an orthographic projection of the center of the lens of the image pickup device 20 on the light-incident side of the display panel 10. After the display device is manufactured, the center of the light-transmitting region 103 can be determined. In one embodiment, the storage device of the image capturing apparatus 100 stores therein the positional information of the center of the light transmitting area 103, and the controller can determine the positional information of the light transmitting area 103 based on the positional information of the center of the light transmitting area 103 and the area size of the light transmitting area 103.
In step 123, position information of the light-transmitting area of the first display area is determined according to the angle of view, the first distance, and position information of the center of the light-transmitting area.
The region covered by the view angle θ of the image pickup device 20 is conical, and the light-transmitting region of the first display region is a region covered by the view angle θ on the light incident side of the display panel 10. Can be used forThe light-transmitting area is known as a circular area. In one exemplary embodiment, the position information of the light transmitting region includes a radius of the light transmitting region and position information of a center of the light transmitting region. The position information of the center of the light-transmitting area is obtained, and the radius of the light-transmitting area can be calculated by adopting the following formula:
where R in the formula represents the radius of the light-transmitting region 103.
In one embodiment, the controller may determine the first distance d1 between the image capturing apparatus 20 and the light incident side of the display panel 10 through steps 1211 to 1213 each time the controller detects that the image capturing apparatus 20 is turned on.
In other embodiments, after detecting that the image capturing apparatus 20 is turned on, the display control method of the display device may further include: it is determined whether the image pickup device 20 is first started.
In one exemplary embodiment, the controller may record each time the camera 20 is detected to be on. If the controller does not find a record of the opening of the image pickup device 20, it may be determined that the image pickup device 20 is first opened. If the controller finds that there is a stored start-up record for the camera 20, it may be determined that the camera 20 is not first turned on.
When the determination result of the controller is yes, it may be determined that the image capturing apparatus 20 is turned on for the first time, and then the controller performs steps 1211 to 1213 to determine a first distance d1 between the image capturing apparatus 20 and the light incident side of the display panel 10, and stores the first distance d1 determined through steps 1211 and 1213. The controller may store the determined first distance d1 in the storage means of the display device.
After the first distance d1 is stored, if the image pickup device 20 is turned on again, the determination structure of the controller 20 is no. When the judging result of the controller is no, the determining the first distance between the light entering side of the display panel away from the image capturing device and the image capturing device includes: and acquiring the stored first distance.
Therefore, the first distance d1 acquired when the camera device 20 is started for the first time is stored, and when the camera device is not started for the first time, the controller can directly acquire the stored first distance d1, so that the data processing flow can be saved, the response speed of the display equipment is faster, and the use experience of a user can be improved.
In step 130, the light-transmitting area is controlled not to be displayed, so that external light enters the image capturing device through the light-transmitting area, and the display area of the first display area and the display area of the second display area are controlled to be displayed, wherein the display area of the first display area refers to an area of the first display area except the light-transmitting area.
The first display area 101 and the second display area 102 are respectively provided with a plurality of pixels. After the controller determines the position information of the light transmitting area 101 of the first display area 101, the pixels located within the light transmitting area 101 are also determined. The controller controls the display area 104 of the first display area 101 and the second display area 102 to display, that is, controls the pixels in the display area 104 and the second display area 102 to emit light. The controller controls the light-transmitting region not to display, that is, controls the pixels in the light-transmitting region 101 not to emit light.
In one embodiment, the display control method of the display device may further include: when the camera is detected not to be started, the first display area 101 and the second display area 102 are controlled to be displayed simultaneously according to the received image data. The image data may be image data of a video frame at this time. Thus, when the camera device 20 does not work, the display panel 10 can realize full-screen display, which is helpful for improving the use experience of the user.
According to the display control method of the display equipment, when the starting of the image pickup device is detected, the position information of the light transmission area of the first display area is determined, the light transmission area is controlled to be not displayed, so that light can enter the image pickup device to enable the image pickup device to image, and other areas except the light transmission area of the first display area and the second display area are controlled to display. Compared with the scheme that all areas of the first display area are not displayed when the image pickup device is started, the method and the device can enable the area of the display panel for displaying the image to be larger when the image pickup device is started, and are beneficial to improving the use experience of a user.
