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. 3 is a schematic structural diagram of a display module according to an exemplary embodiment, where the display module may be applied to a display device such as a mobile phone, a tablet computer, a television, and the like. As shown in fig. 3, the display module includes the following structure.
A display panel 11.
In one embodiment, the display panel may be a liquid crystal display panel or an organic light emitting diode display panel.
The fingerprint sensor is arranged in the display panel and used for determining whether a user inputs a fingerprint in the display panel or not and generating a sensing signal according to the fingerprint input by the user in the display panel.
In one embodiment, the fingerprint sensor may be maintained in an operational state to continuously determine whether a user is entering a fingerprint in the display panel. The fingerprint identification device can also be started when receiving an instruction, so that whether a user inputs a fingerprint in the display panel is determined when the fingerprint identification device is started, for example, when a display device where a display module is located performs fingerprint payment verification, the fingerprint identification device can receive the instruction from a processor and/or a control chip, so that fingerprint identification is determined to be required, and the fingerprint identification device is started to determine whether the user inputs the fingerprint in the display panel. In different application scenarios, the first sensor may be triggered to start by different instructions, which is not described in detail in this embodiment.
In one embodiment, as shown in fig. 3, in case the fingerprint sensor 12 is a capacitive sensor, the capacitive sensor may be arranged at the light exit side of the display panel 11.
Because the valleys of the fingerprint are different from the ridges of the fingerprint, the pressing of the display panel causes the capacitance values of the capacitance sensors at different positions in the display panel to change, and then different current signals generated by the change of the capacitance values of different capacitance sensors can be used as sensing signals and further transmitted to the processor by the fingerprint sensor to identify the pattern of the fingerprint.
When the capacitive sensors generate the sensing signals, the fact that a user inputs a fingerprint in the display panel is determined, the pressure of the user pressing the display panel can be determined according to the change of the capacitance of each capacitive sensor, and the fact that the user inputs the fingerprint in the display panel is determined under the condition that the pressure is larger than the preset pressure.
In one embodiment, as shown in fig. 3, in case the fingerprint sensor 12 is a capacitive sensor, the capacitive sensor may be disposed between the display panel 11 and the protective layer 13. In addition, the capacitive sensor may be disposed in the display panel, for example, between the color filter substrate and the upper polarizer, according to the requirement, and is not limited to the structure shown in fig. 3.
Fig. 3 shows only the structure in the case where the fingerprint sensor is a capacitive sensor, but the fingerprint sensor may be implemented by other structures, and is not limited to the structure shown in fig. 3, nor to the manner described above, to determine whether the user enters a fingerprint on the display panel.
And the control chip (not shown in the figure) is electrically connected with the display panel and controls the display panel to flash at a brightness larger than the current brightness under the condition that the user is determined to input the fingerprint in the display panel.
In one embodiment, the control chip may be a Chip On Glass (COG) chip, or may be a chip with other structures. The control chip can be electrically connected to the pixel units in the display panel, and can receive the control instruction sent by the fingerprint sensor when the fingerprint sensor determines that a user inputs a fingerprint on the display panel, and according to the control instruction, the pixel units in the display panel can be controlled to increase the brightness, maintain the increased brightness for a preset time, such as 0.1 second, and then recover to the brightness before the increase, so that the display panel flickers with the brightness larger than the current brightness.
In one embodiment, when a user enters a fingerprint in the display panel, the display panel can be controlled to flash at a brightness higher than the current brightness, so that a clear response is made to the operation of entering the fingerprint by the user, so that the user is definitely aware that the display panel is identifying the fingerprint, and the user experience is improved.
Optionally, the fingerprint sensor comprises:
a first sensor for determining whether a user enters a fingerprint in the display panel;
and the second sensor is used for generating a sensing signal according to the fingerprint input by the user in the display panel.
In one embodiment, the two functions of determining whether the user enters the fingerprint in the display panel and generating the sensing signal according to the fingerprint entered in the display panel by the user can be respectively determined by different sensors. On one hand, the problem that when one sensor fails to realize the two functions can be solved; on the other hand, the processor can respectively determine whether the user inputs the fingerprint in the display panel according to the signals of different sensors, and generate the induction signal according to the fingerprint input by the user in the display panel, so that the calculation logic of the processor is simplified, and the robustness is improved.
Optionally, the first sensor is a pressure sensor;
the user data is the pressure of a user on the display panel, and the pressure sensor determines that the user inputs a fingerprint in the display panel under the condition that the pressure is greater than the preset pressure.
In one embodiment, the pressure sensor may be one or more capacitive sensors, and a corresponding current may be generated according to a change in capacitance of the capacitive sensor caused by the pressure of the user, and the magnitude of the pressure of the user on the display panel may be calculated according to the generated current.
Optionally, the first sensor is a distance sensor;
the user data is the distance from a user to the display panel, and the distance sensor determines that the user inputs a fingerprint in the display panel under the condition that the distance is smaller than a preset distance.
In one embodiment, the distance sensor may be an infrared sensor or an ultrasonic sensor. Taking the ultrasonic sensor as an example, the ultrasonic sensor specifically comprises a transmitting end and a receiving end, wherein the transmitting end is used for transmitting an ultrasonic signal to a user, the receiving end can determine the propagation time consumed by the ultrasonic signal from transmission to reflection back to the receiving end according to the time of the received ultrasonic signal and the time of the transmitting end transmitting the ultrasonic signal, and then the distance from the finger of the user to the display panel can be calculated according to the propagation time and the propagation speed of the ultrasonic signal.
Optionally, the fingerprint sensor is a capacitive sensor.
In one embodiment, due to the different heights of the valleys and ridges of the fingerprint, pressing the display panel causes the capacitance values of the capacitive sensors at different positions in the display panel to change differently, and then the change in the capacitance values of the capacitive sensors generates different current signals that can be used as sensing signals to be further transmitted by the fingerprint sensor to the processor to identify the pattern of the fingerprint.
Optionally, the fingerprint sensor is an ultrasonic sensor.
In one embodiment, the reflection of the ultrasonic wave is different due to the different heights of the valleys and ridges of the fingerprint, and the pattern of the fingerprint can be determined according to the difference of the received ultrasonic wave signals reflected by the fingerprint.
Optionally, the fingerprint sensor is a photosensor.
In one embodiment, the reflection of light is different due to the different heights of the valleys and ridges of the fingerprint, and the pattern of the fingerprint can be determined according to the difference of the received ultrasonic signals reflected by the fingerprint.
Fig. 4 is a schematic structural diagram of another display module according to an exemplary embodiment, in which the display panel 11 includes a fingerprint identification area 111 for emitting light to a fingerprint when it is determined that a user enters the fingerprint in the display panel;
the control chip is configured to control the other area 112 of the display panel 11 and the fingerprint identification area 111 to emit light with brightness greater than the current brightness synchronously when it is determined that a user enters a fingerprint in the display panel.
In one embodiment, in the case that the fingerprint sensor is a photosensor, the photosensor may be disposed in a pixel unit of the display panel, wherein one photosensor may be disposed in each pixel unit, a plurality of photosensors may be disposed in one pixel unit, and one photosensor may be disposed in a plurality of pixel units. The specific location of the photosensor is not shown in fig. 4.
In one embodiment, when a user enters a fingerprint in the display panel, the fingerprint identification area in the display panel can be controlled to emit light with brightness higher than the current brightness to the finger of the user, so that the photoelectric sensor can determine the fingerprint graph according to the light reflected by the fingerprint. But this may cause the user to visibly observe the location of the fingerprint identification area in the display panel, making the display panel look unsightly overall.
Therefore, when the fingerprint identification area in the display panel is controlled to emit light with the brightness larger than the current brightness to the finger of the user, other areas except the fingerprint identification area in the display panel can be controlled to emit light with the brightness larger than the current brightness synchronously with the fingerprint identification area, so that when the user identifies the fingerprint, the seen display panel flickers integrally at the brightness larger than the current brightness (for example, the brightness of each pixel unit in the display panel can be controlled to be improved by a preset percentage), and not only the fingerprint identification area flickers at the brightness larger than the current brightness, so that the user is prevented from obviously observing the fingerprint identification area, and the display panel is more attractive.
Optionally, when it is determined that the user inputs a fingerprint in the display panel, the control chip controls other areas of the display panel to emit light rays with the same brightness and brightness higher than the current brightness synchronously with the fingerprint identification area.
In an embodiment, on the basis of the embodiment shown in fig. 4, when it is determined that a user enters a fingerprint in the display panel, other regions of the display panel may be further controlled to emit light rays with the same brightness in synchronization with the fingerprint identification region, that is, on the basis of ensuring that the display panel flickers with a brightness greater than the current brightness as a whole, the luminance of each pixel unit is further ensured to be the same when the display panel flickers, so that each region of the display panel viewed by the user flickers with the same brightness, thereby further ensuring that the user cannot easily observe the fingerprint identification region in the display panel.
In one embodiment, the fingerprint identification areas may be set to correspond to the areas where the photosensors are located, and have the same area and the same shape. In the embodiment, the fingerprint identification area is smaller, so that the internal wiring of the display panel is simplified, and the pixel units in the fingerprint identification area can conveniently control to emit light rays with brightness higher than the current brightness.
In one embodiment, the fingerprint identification area may be set to correspond to the area where the photosensor is located, and has the same shape but an area larger than that of the area where the photosensor is located. Because different users point the variation in size to can not guarantee during fingerprint identification that the fingerprint is corresponding with fingerprint sensor completely, consequently based on this embodiment, can be greater than the fingerprint identification region of the regional area in photoelectric sensor place through the area and to fingerprint emission light, thereby can shine the fingerprint of bigger area, and then guarantee that fingerprint sensor can receive the light of the fingerprint reflection of bigger area, so that accurately confirm the fingerprint figure.
