In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The display screen provided by the embodiment of the present application is described in detail with reference to fig. 1 to 5 through specific embodiments and application scenarios thereof.
Referring to fig. 1 to 5, a display panel according to an embodiment of the disclosure includes a light emitting layer 110 and a filter layer 120. The light emitting layer 110 includes an infrared display region 110a to emit infrared light outside the display screen 100 through the infrared display region 110 a. The infrared display area 110a includes a first visible light emitting unit 111 and an infrared light emitting unit 112. The first visible light emitting units 111 are multiple and distributed in an array. The infrared light emitting units 112 may also be multiple and distributed in an array.
In this embodiment, the infrared display area 110a emits visible light through the first visible light emitting unit 111 to satisfy the image display function. The infrared display area 110a satisfies the infrared device function by emitting infrared light through the infrared light emitting unit 112. It should be noted that the infrared display area 110a can satisfy the function of the off-screen infrared device by emitting infrared light through the infrared light emitting unit 112, but is not limited to the function of the off-screen infrared device.
The first visible light emitting unit 111 is provided with a mounting hole, and the infrared light emitting unit 112 is provided in the mounting hole. The infrared light emitting unit 112 is arranged in the mounting hole, so that the infrared light emitting unit 112 is prevented from occupying the space between two adjacent first visible light emitting units 111, the reduction of the distance between the two adjacent first visible light emitting units 111 is facilitated, and the display performance of the display screen is improved. The infrared light emitting unit 112 is integrated in the display screen 100, so that not only can the infrared light emitted by the infrared light emitting unit 112 be prevented from being blocked, and the performance of the infrared light emitting unit 112 be improved, but also the infrared light emitting unit 112 can be prevented from occupying the space below the display area of the display screen, and the purpose of saving the internal space of the device can be achieved.
Referring to fig. 1 and 2, the filter layer 120 is disposed opposite to the infrared light emitting unit 112, and a projection of the filter layer 120 toward the light emitting layer 110 covers the infrared light emitting unit 112. The infrared light emitting unit 112 is sensitive to visible light and is easily interfered by visible light, so that the performance of the infrared light emitting unit 112 is reduced. In this embodiment, by providing the filter layer 120, other stray light except for infrared light can be effectively filtered, and it is ensured that only infrared light passes through the area corresponding to the infrared light emitting unit 112, so that the performance of the infrared light emitting unit 112 is further improved.
Referring to fig. 1, in the infrared display area 110a, the infrared light emitting units 112 correspond to the first visible light emitting units 111 one by one, so that a distance between two adjacent infrared light emitting units 112 can be reduced, a luminous flux of infrared light in a unit area can be increased, an illumination intensity of the infrared light can be increased, and an overall performance of the infrared light emitting units 112 in the infrared display area 110a after combination can be improved. The infrared light emitted from the infrared display area 110a may be used for different functions, such as touch protection of a display screen, light supplement of an infrared camera, infrared fingerprint recognition, iris recognition, and the like. The different functions are different in the illumination intensity requirement of the infrared light emitted by the infrared display area 110a, and then the density of the infrared light emitting unit 112 in the infrared display area 110a can be set as required, so that the illumination intensity of the infrared light emitted by the infrared display area 110a of the display screen can be adjusted, the performance of the infrared display area 110a can be optimized, and the infrared light emitted by the infrared display area 110a can be used in different applications.
Referring to fig. 1, the light emitting layer 110 further includes a non-infrared display region 110b, and the non-infrared display region 110b includes a plurality of second visible light emitting units 113. The second visible light emitting unit 113 in the non-infrared display area 110b and the first visible light emitting unit 111 in the infrared display area 110a form a complete visible light display area of the display screen, thereby ensuring that each area of the display screen 100 can normally display. Moreover, the infrared light emitting units 112 in the infrared display area 110a are embedded in the first visible light emitting units 111, so that the arrangement and density of the first visible light emitting units 111 in the infrared display area 110a are the same as the arrangement and density of the second visible light emitting units 113 in the non-infrared display area 110b, thereby ensuring that the non-infrared display area 110b and the infrared display area 110a have the same display performance.
The first visible light emitting unit 111 includes R pixels, G pixels, and B pixels. The infrared light emitting unit 112 is an IR pixel. Specifically, mounting holes for mounting IR pixels are provided in the R pixels, G pixels, and B pixels in the infrared display region 110 a. Embedding IR pixels in the mounting holes of the R, G, and B pixels forms a pixel combination capable of emitting infrared light. Since the IR pixels are embedded in the R pixels, the G pixels, and the B pixels, the arrangement and density of the R pixels, the G pixels, and the B pixels in the infrared display region 110a are the same as those of the R pixels, the G pixels, and the B pixels in the non-infrared display region 110B, thereby ensuring that the display performance of the infrared display region 110a is the same as that of the non-infrared display region 110B.
The display screen 100 is an OLED display screen. The first visible light emitting unit 111 and the second visible light emitting unit 113 are made of the same material. Specifically, the first visible light emitting unit 111 and the second visible light emitting unit 113 are made of visible light organic light emitting materials. The infrared light emitting unit 112 is made of an infrared organic light emitting material. Optionally, the infrared light emitting unit 112 is made of NZ2TPA material. The wavelength range of infrared light emitted by the NZ2TPA material is 780 nm-1100 nm, the turn-on voltage of the NZ2TPA material is lower than that of the visible light organic luminescent material, and further the first visible light luminescent unit 111, the second visible light luminescent unit 113 and the infrared light luminescent unit 112 can be turned on and turned off by adjusting the input voltage. Specifically, only the infrared light emitting unit 112 in the light emitting layer 110 can be lit by lowering the voltage. In addition, the NZ2TPA material has the luminescence quantum yield of 60% in a pure film state, which is the highest value of the luminescence quantum yield in the organic near-infrared luminescence small molecules at present. When the NZ2TPA material is used as an infrared light emitting material of an undoped infrared OLED device, the maximum external quantum efficiency of the infrared light emitting unit 112 reaches 3.9%, which is also the highest external quantum efficiency of the undoped near-infrared OLED device based on small organic molecules at present. More importantly, the efficiency roll-off speed of the NZ2TPA material is very slow, and the external quantum efficiency of the infrared light emitting unit 112 is still as high as 2.8% at a luminance of 1000cd m-2.
The display screen 100 includes a first circuit and a second circuit, the first circuit is connected to the first visible light emitting unit 111 and/or the second visible light emitting unit 113, and the first circuit provides power for the first visible light emitting unit 111 and/or the second visible light emitting unit 113 to emit light. The second circuit is connected to the infrared light emitting unit 112, and the second circuit provides power for the infrared light emitting unit 112 to emit light. The first circuit and the second circuit are independent of each other. The first visible light emitting unit 111 and the infrared light emitting unit 112 are powered by different circuits, so that the first visible light emitting unit 111 and the infrared light emitting unit 112 can be independently turned on or off as needed. Further, the first visible light emitting unit 111 and the second visible light emitting unit 113 adopt the same lighting power supply, so that the first visible light emitting unit 111 and the second visible light emitting unit 113 can be simultaneously lighted or extinguished, and synchronous display of the infrared display area 110a and the non-infrared display area 110b is ensured. Specifically, when the infrared function is required, the infrared light emitting unit 112 is lighted by controlling the second circuit. When the infrared function is not required, the infrared light emitting unit 112 is turned off by controlling the second circuit. Since the first circuit and the second circuit are independent of each other, the infrared light emitting unit 112 and the first visible light emitting unit 111 can be lit at the same time, or one of them can be lit, which satisfies more usage scenarios. Optionally, the first circuit and the second circuit are TFT circuits. Of course, the first visible light emitting unit 111 and the second visible light emitting unit 113 may also be powered by independent circuits, and the first visible light emitting unit 111 and the second visible light emitting unit 113 are simultaneously turned on or off by a synchronous control circuit.
Optionally, the first circuit and the second circuit are both pixel display circuits, where the first circuit controls each of the first visible light emitting unit 111 and the second visible light emitting unit 113 to be turned on or off. The second circuit controls each infrared light emitting unit 112 to be independently turned on or off. Specifically, the second circuit controls the number and/or density of the lighted infrared light emitting units 112 according to the specific application of the infrared light emitted by the infrared display area 110a, so that the performance of the infrared display area 110a is suitable for different usage scenarios.
The display screen 100 further includes a base layer, which is stacked with respect to the light emitting layer 110. The base layer provides support for the first and second circuits. Specifically, a first circuit is disposed in a region of the base layer opposite to the first visible light emitting unit 111 and the second visible light emitting unit 113 in the light emitting layer 110, and a second circuit is disposed in a region of the base layer opposite to the infrared light emitting unit 112 in the light emitting layer 110. Specifically, a first circuit for controlling the light emission of the first visible light emitting unit 111 and the second visible light emitting unit 113 is fabricated by etching on the base layer, and a second circuit for controlling the light emission of the infrared light emitting unit 112 is fabricated by etching on the base layer.
It should be noted that, a display surface is a surface of the display panel 100, the first circuit and the second circuit are located on a side of the light emitting layer 110 away from the display surface, and then the infrared light emitted by the infrared light emitting unit 112 does not irradiate the first circuit and the second circuit, so that the first circuit and the second circuit can be prevented from being damaged due to irradiation of the infrared light. Therefore, integrating the infrared light emitting unit 112 into the display screen 100 can also improve the performance of the infrared light emitting unit 112 by increasing the energy of the infrared light emitted by the infrared light emitting unit 112.
Referring to fig. 4, the display screen 100 further includes a cathode layer 130 and an anode layer 140, and optionally, the cathode layer 130 and the anode layer 140 are stacked on the light emitting layer 110, and the light emitting layer 110 is located between the cathode layer 130 and the anode layer 140.
