Fig. 2 is a flowchart illustrating a display method according to an exemplary embodiment, and the display method provided by the embodiment of the present disclosure applies the display panel provided in the corresponding embodiment of fig. 1A. As shown in fig. 2, a display method provided by an embodiment of the present disclosure includes the following steps.
In step 201, a display trigger signal is acquired, wherein the display trigger signal includes image information of an image to be displayed.
In step 202, a control signal is generated according to the image information, wherein the control signal is used for controlling whether each built-in infrared emitter works or not.
In step 203, the image to be displayed is implicitly displayed according to the working result of each infrared emitter, wherein the image to be displayed can be identified by an external infrared scanning device.
The display method provided by the embodiment of the disclosure includes the steps of acquiring a display trigger signal including image information of an image to be displayed, generating a control signal indicating whether each built-in infrared emitter works or not according to the image information, and then performing hidden display on the image to be displayed according to a working result of each infrared emitter, thereby realizing the method for performing hidden display on the image. In addition, if the current picture is displayed on the display screen when the image is displayed in a hidden mode, the two images can be displayed on the same display screen.
Wherein, acquire and show trigger signal includes:
receiving a display trigger signal sent by near-field infrared scanning equipment;
or receiving communication messages sent by other terminals, wherein the communication messages carry display trigger signals; the display trigger signal in the communication message is parsed.
Optionally, the image to be displayed includes a two-dimensional code, a barcode, text information, picture information, or a combination of text and image.
Optionally, the display method further includes:
and displaying a current picture on a display screen of the screen, wherein the current picture can be recognized by human eyes.
With reference to the content of the embodiment corresponding to fig. 2, fig. 3A is a flowchart illustrating a display method according to an exemplary embodiment, and the display method provided by the embodiment of the disclosure applies to the display panel provided by the embodiment corresponding to fig. 1A. As shown in fig. 3A, the display method provided by the embodiment of the present disclosure is applied to a terminal, and includes the following steps.
In step 301, a display trigger signal is obtained, where the display trigger signal includes image information of an image to be displayed.
The display trigger signal is a signal for triggering the hidden display of the image to be displayed according to the embodiment of the present disclosure. The image to be displayed may be any one of a two-dimensional code, a barcode, text information, picture information, or a combination of text and images.
The display trigger signal may include all information of the image to be displayed, and the subsequent terminal may directly generate the control signal according to the image information carried in the display trigger signal. The display trigger signal can only include key information of the image to be displayed, and the subsequent terminal generates all contents of the image to be displayed according to the key information and further generates a control signal according to all contents of the image to be displayed. For example, when the image to be displayed is a two-dimensional code, the display trigger signal may only include information of the amount to be paid, the payee, and the like, and the subsequent terminal generates the two-dimensional code including the amount to be paid and the payee.
Specifically, when the display trigger signal is acquired, there are two ways including, but not limited to:
the first mode is as follows: and receiving a display trigger signal sent by the near-field infrared scanning equipment.
The terminal can receive the display trigger signal sent by the near-field infrared scanning device based on a communication protocol with the near-field infrared scanning device.
The second mode is as follows: receiving communication messages sent by other terminals, wherein the communication messages carry display trigger signals; the display trigger signal in the communication message is parsed.
Wherein, other terminals can send communication messages in the forms of short messages, instant communication messages and the like. The manner of parsing the display trigger signal in the communication message may be implemented based on an existing information extraction manner.
In step 302, a control signal is generated according to the image information, wherein the control signal is used for controlling whether each built-in infrared emitter works or not.
In conjunction with the display panel shown in fig. 1A, each control line is gated, and when it is required for the infrared emitters in a certain row to operate, the row control line is controlled to be turned on. Since only a part of all the infrared ray emitters of the display panel may be operated when displaying the image to be displayed, the terminal generates the control signal according to the image information in order to determine which infrared ray emitters are operated. For example, for an infrared emitter that needs to operate, its voltage may be set to 1; for the infrared emitters which do not need to work in the display, the voltage of the infrared emitters can be set to be 0, and the voltages of all the infrared emitters are combined to obtain the control signal.
In step 303, the image to be displayed is implicitly displayed according to the working result of each infrared emitter, wherein the image to be displayed can be identified by an external infrared scanning device.
Since the light emitted by the infrared emitter is not recognized by the human eye, but can be recognized by an external infrared scanning device, it is equivalent to displaying the image to be displayed in a hidden manner with respect to the human eye.
When the image to be displayed is a two-dimensional code or a bar code, the external infrared scanning device can scan the two-dimensional code or the bar code and the like to pay or acquire specific information therein, so that the method can be applied to a payment scene, an information acquisition scene and the like. The hidden display of the images can ensure that the information is not leaked. When the image to be displayed is any one of text information, picture information or combination of text and images, the image is displayed in a hidden mode, and privacy can be protected. For example, when the image to be displayed is bank account information or credit card information, the security level can be improved by hidden display as compared with direct display on a display screen.
In step 304, a current frame is displayed on a display screen of the screen, wherein the current frame is recognizable by human eyes.
The implicit display in step 303 may be implemented when the terminal is in a black screen state. However, when the hidden display is performed, the display screen of the terminal may be currently displaying the current picture, and the current picture is recognizable to human eyes, so that the hidden display of the image to be displayed is performed while the current picture is displayed on the display screen.
FIG. 3B is a diagram illustrating a display of a current picture according to an example embodiment. FIG. 3C is a diagram illustrating an image to be displayed, according to an exemplary embodiment. Fig. 3B is recognizable to human eyes, and fig. 3C is recognizable to external infrared scanning devices. As can be seen from fig. 3B and 3C, one display screen displays two kinds of images at the same time, one recognizable to the human eye and one recognizable to the infrared scanning apparatus. At the moment, if some application scenes need to pay through the terminal, if the terminal display screen displays the current picture, the current picture does not need to be switched, and the payment two-dimensional code is directly and implicitly displayed.
According to the display method provided by the embodiment of the disclosure, the current picture which can be identified by human eyes is displayed on the display screen of the screen while the image to be displayed which can be identified by the external infrared scanning equipment is displayed, so that two different images can be displayed by the display screen at the same time, the display mode is more flexible, and the confidentiality and the security level of the information with higher confidentiality and security level can be better ensured. In addition, when the display screen displays the current picture, other information can be displayed in a hidden mode, so that the information can be displayed without switching the current picture, and the operation is simplified.
The embodiment of the present disclosure further provides a display device, which includes the display panel provided in the embodiment corresponding to fig. 1A. Details regarding the display panel have been described in detail in the embodiment corresponding to fig. 1A, and will not be elaborated here.
