Detailed Description
In order to facilitate an understanding of the present application, a more complete description of the present application will now be provided with reference to the relevant figures. Preferred embodiments of the present application are shown in the drawings. This application may, however, be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to and integrated with the other element or intervening elements may also be present. The terms "mounted," "one end," "the other end," and the like are used herein for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
In order to solve the problem of the conventional under-screen fingerprint unlocking display screen with improved luminous intensity that has a low lifetime, in one embodiment, as shown in fig. 1, 2, 3, 4 and 5 (B in fig. 2 represents a blue pixel unit, G represents a green pixel unit, R represents a red pixel unit, and FL represents an auxiliary light emitting unit; PDL in fig. 3, 4 and 5 represents an organic insulating layer, PE represents a pixel electrode, array represents a panel substrate), a display panel is provided including a fingerprint recognition area 11;
an auxiliary light emitting unit 113 is arranged between the pixel units 111 in the fingerprint identification area 11, and a light detection module 115 is arranged in the fingerprint identification area 11;
wherein, the auxiliary light emitting unit 113 is controlled to be lightened by a control chip of the display panel when receiving a fingerprint identification instruction; the light detection module 115 collects light reflected by the finger to form a fingerprint image of the finger and transmits the fingerprint image to the control chip of the display panel.
In order to improve the screen ratio of the display screen on the electronic device, a common method is to implant the fingerprint recognition function on the display panel, and a fingerprint recognition area for fingerprint recognition is disposed on the display panel.
In one example, any position in the display area of the display panel can be used for fingerprint identification (for example, in a mobile phone unlocking scene or in a payment confirmation identity scene), namely, the area of the fingerprint identification area is equal to the display area of the display panel, and the display panel is made to have two functions of display and fingerprint identification, and in this example, one of the following two fingerprint identification modes can be adopted: in the first mode, when fingerprint identification is needed, an auxiliary light-emitting unit in the whole fingerprint identification area is lightened; in the second mode, when fingerprint identification is needed, only the auxiliary light-emitting units in the finger touch area can be lightened. The first mode has high power consumption on the electronic equipment, and the second mode is beneficial to saving the power of the electronic equipment.
In another example, a specific area in the display area of the display panel can be used for fingerprint identification, that is, the area of the fingerprint identification area is smaller than the display area of the display panel, the specific area on the display panel is made to have two functions of display and fingerprint identification, the size of the area of the fingerprint identification area can be determined according to practical use requirements, in one example, the area of the fingerprint identification area can be the average area of fingers, so that the manufacturing process flow of the display panel is simplified to the greatest extent, the manufacturing cost is saved, and the electric energy of the electronic equipment can be saved to the greatest extent. Further, the location of the fingerprint recognition area may be determined according to practical needs, for example, the location of the edge of the display area of the display panel, or the location of the fingerprint recognition area in the middle area of the display panel. In this example, the fingerprint recognition area may be a circular area, an elliptical area, or a rectangular area.
The fingerprint identification area comprises auxiliary light-emitting units, and specifically, the auxiliary light-emitting units are arranged between the pixel units, and when fingerprint identification is needed, the auxiliary light-emitting units are electrified to emit light under the control of a control chip of the display panel. In one example, the light emission luminance of the auxiliary light emitting unit is fixed, i.e., the light emission luminance of the auxiliary light emitting unit is the same regardless of the use state of the electronic device. In another example, the light emitting brightness of the auxiliary light emitting unit may be changed according to the operating state of the electronic device, that is, the control chip of the display panel controls the auxiliary light emitting unit to emit light with different brightness according to the operating state of the electronic device, specifically, for example, when the electronic device is in a standby state, the control chip controls the auxiliary light emitting unit to emit light with high brightness, when the electronic device is in a bright screen operation, the control chip controls the auxiliary light emitting unit to emit light with low brightness, in one case, when the electronic device is running a payment application program, fingerprint collection is needed to confirm payment, and the control chip controls the auxiliary light emitting unit to emit light with low brightness. Specifically, the brightness of the light emitted by the auxiliary light emitting unit can be set according to actual requirements.
The control chip obtains fingerprint identification instructions in a very large number of ways, for example, when the electronic device is in a black screen standby state, the mobile phone is detected to be lifted, when the electronic device is in the black screen standby state, a power key is pressed, or when the electronic device runs a certain application program, the application program sends out fingerprint identification requests, and the like.
The fingerprint identification area also comprises a light detection module, wherein the light detection module is used for collecting light rays emitted by the finger and processing the light rays to form a fingerprint image of the finger, then the fingerprint image is transmitted to the control chip to control the comparison of the fingerprint image and the predicted fingerprint image, and the fingerprint identification is successful when the fingerprint image and the predicted fingerprint image are matched.
In order to reduce the manufacturing cost and save the manufacturing time, instead of providing auxiliary light emitting units between all pixel units, for example, in one example, as shown in fig. 6 (B represents a blue pixel unit, G represents a green pixel unit, R represents a red pixel unit, and FL represents an auxiliary light emitting unit in fig. 6), auxiliary light emitting units are provided between the blue pixel unit and the red pixel unit in the fingerprint identification area. In another example, as shown in fig. 7 (B represents a blue pixel unit, G represents a green pixel unit, R represents a red pixel unit, and FL represents an auxiliary light emitting unit) an auxiliary light emitting unit is provided between the red pixel unit and the green pixel unit in the fingerprint recognition area. In still another example, as shown in fig. 8 (B in fig. 8 denotes a blue pixel unit, G denotes a green pixel unit, R denotes a red pixel unit, and FL denotes an auxiliary light emitting unit), an auxiliary light emitting unit is provided between the blue pixel unit and the green pixel unit in the fingerprint recognition area. The auxiliary light-emitting units are selectively arranged, so that the manufacturing process flow of the display panel is simplified, and the production efficiency is improved.
The auxiliary light emitting unit is realized in various forms, and in one example, the auxiliary light emitting unit is a vapor deposition color mixing unit between pixel units in the fingerprint identification area; the vapor deposition color mixing unit is electrically contacted with the pixel electrode on the display panel and is lightened under the control of the control chip. It should be noted that, in the process of manufacturing the display panel, the vapor deposition area is larger than the display area, so that a vapor deposition color mixing unit is formed between the pixel units, that is, the vapor deposition color mixing unit includes two luminescent materials of adjacent pixel units, for example, the adjacent pixel units are a red pixel unit and a green pixel unit, and the vapor deposition color mixing unit includes a red luminescent material and a green luminescent material; the adjacent pixel units are a red pixel unit and a blue pixel unit, and the vapor deposition color mixing unit comprises a red luminescent material and a blue luminescent material; the adjacent pixel units are blue pixel units and green pixel units, and the vapor deposition color mixing unit comprises a blue luminescent material and a green luminescent material.
In order to reduce the manufacturing cost and save the manufacturing time, instead of providing auxiliary light emitting units between all pixel units, auxiliary light emitting units may be selectively provided between pixel units, for example, in one example, vapor deposition color mixing units between blue pixel units and red pixel units in the fingerprint identification area are selected as auxiliary light emitting units. In another example, an evaporated color mixture unit between red pixel units and green pixel units within the fingerprint recognition area is selected as the auxiliary light emitting unit. In yet another example, a vapor deposition color mixing unit between a blue pixel unit and a green pixel unit within a fingerprint recognition area is selected as the auxiliary light emitting unit. Further, since the light detection module is sensitive to blue light and green light with higher energy, it is preferable to select the vapor deposition color mixing unit between the blue pixel unit and the green pixel unit in the fingerprint identification area as the auxiliary light emitting unit.
Specifically, a groove is formed in a pixel Bank between pixel units in the fingerprint identification area; the pixel electrode is arranged at the bottom of the groove; the vapor deposition color mixing unit is arranged in the groove and is electrically contacted with the pixel electrode.
The display panel provided by the embodiments of the application comprises a fingerprint identification area; an auxiliary light-emitting unit is arranged between pixel units in the fingerprint identification area, and a light detection module is arranged in the fingerprint identification area; the auxiliary light-emitting unit is controlled to be lightened by a control chip of the display panel when receiving a fingerprint identification instruction; the light detection module collects light reflected by the finger to form a fingerprint image of the finger, and transmits the fingerprint image to the control chip of the display panel, the auxiliary light-emitting unit is used for assisting in light emission when the fingerprint is required to be identified, the brightness of emitted light of the finger during fingerprint identification is improved, the problem that the service life of the display panel is reduced due to the fact that the brightness of a pixel unit of the display panel is improved is avoided, the service life of the display panel is prolonged, and the accuracy of fingerprint identification is improved.
In one embodiment, an electronic device is further provided, including the display panel described in each embodiment of the display panel of the present application.
It should be noted that, in this embodiment, the display panel is the same as the display panel described in each embodiment of the display panel of the present application, and specific reference is made to each embodiment of the display panel of the present application, which is not repeated here.
