Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The display panel and the display device can be applied to display products such as mobile phones, and the light emitting type of the display panel can be an organic light emitting mode.
As shown in fig. 1, in the embodiment of the present application, there is provided a display device including a display panel 100 and an external driving circuit 200. The display panel 100 is used for light emitting display. The external driving circuit 200 is electrically connected to the display panel 100 for providing driving signals to the display panel 100.
First embodiment
Referring to fig. 2 and 3, the display panel 100 includes a display layer group 110 and a package layer group 120. Display layer group 110 may include a substrate 111, a thin-film-transistor layer 112, and a light-emitting layer group 113. The substrate 111 may be a glass substrate or a flexible substrate formed of a thin film material. Thin-film transistor layer 112 and light-emitting sub-layer group 113 are sequentially stacked on substrate 111. And the light emitting sub-layer group 113 forms a number of sub-pixels. Thin-film-transistor layer 112 is used to control the driving of each sub-pixel.
The light emitting layer group 113 includes an anode layer (not shown), an organic light emitting layer (not shown), and a cathode layer (not shown). The anode layer may comprise a number of individual anode units. Each sub-pixel is correspondingly provided with an anode unit. The organic light emitting layer of each sub-pixel has different organic light emitting materials, and then emits light with different colors. The cathode layer may comprise a common cathode plate. Several sub-pixels may share a common cathode plate.
A voltage difference is formed between the anode unit and the cathode plate of each sub-pixel, electrons and holes are respectively injected from the cathode plate and the anode unit and are transmitted to the organic light-emitting layer, and meet in the organic light-emitting layer to form excitons, and the excitons enable the organic light-emitting material of the organic light-emitting layer to be excited and radiated to emit light.
Encapsulation layer set 120 includes encapsulation layer 121. The sealing layer 121 is used to adhere to the display panel 100 and further seal each sub-pixel of the display panel 100. In addition, the package layer group of the present application further includes a touch sub-layer group 122. The touch sub-layer group 122 includes a plurality of first touch electrodes 1221 and a plurality of second touch electrodes 1222. The first touch electrodes 1221 and the second touch electrodes 1222 are arranged in an insulated and crossed manner, so that a touch capacitor is formed at the crossed and overlapped position, thereby having a touch function. The first touch electrodes 1221 may be arranged in parallel, and the second touch electrodes 1222 may be arranged in parallel, so that the touch capacitors are uniformly distributed in the touch sub-layer group 122, and thus the touch function is uniformly implemented at all positions. Of course, the arrangement of the first touch electrodes 1221 and the second touch electrodes 1222 is not limited thereto. For example, the first touch electrodes 1221 or the second touch electrodes 1222 may be partially parallel or non-parallel, etc. As long as the two can form a touch capacitance in an intersecting manner.
In the embodiment of the present disclosure, the touch sub-layer 122 is formed on the package layer 121, and then the touch function is integrated on the package layer 121 by an on-cell method. Therefore, the package layer group 120 of the embodiment of the present application integrates the functions of packaging and touch control. The display device using the display panel 100 of the present application does not need to be additionally provided with a touch panel, and thus the thickness of the display device is reduced.
Meanwhile, at least a partial area of the touch sub-layer 122 in the embodiment of the present application is a fingerprint identification area. The first touch electrode 1221 in the fingerprint identification area is patterned to form a fingerprint identification electrode 1223; or the second touch electrode 1222 of the fingerprint identification area is patterned to form a fingerprint identification electrode 1223; or the first touch electrode 1221 and the second touch electrode 1222 of the fingerprint identification area are simultaneously patterned to form the fingerprint identification electrode 1223.
The line width of the touch electrodes (including the first touch electrode 1221 and the second touch electrode 1222) is generally large, which is difficult to be used for fingerprint recognition. According to the application, the touch electrode with the larger size is subjected to graphical processing, so that fine circuit design can be performed, and the fingerprint identification electrode 1223 is formed. Therefore, the package layer group 120 further integrates the fingerprint identification function in the embodiment of the present application. The package layer group 120 integrates the functions of packaging, touch control, and fingerprint recognition at the same time, thereby realizing high integration of the display panel 100.
In this embodiment, a local area of the touch sub-layer group 122 may be a fingerprint identification area, or all areas of the touch sub-layer group 122 may be fingerprint identification areas.
In this embodiment, the fingerprint recognition electrode 1223 may include a plurality of first fingerprint electrodes 1223a and a plurality of second fingerprint electrodes 1223 b. The first touch electrode 1221 and the second touch electrode 1222 may be strip electrodes, so as to facilitate patterning to form the fingerprint identification electrodes 1223 uniformly distributed, so that all areas of the touch sub-layer group 122 have a fingerprint identification function (i.e., all areas of the touch sub-layer group 122 are fingerprint identification areas). Of course, at this time, a local area of the touch sub-layer group 122 may also be a fingerprint identification area.
Specifically, the first touch electrode 1221 in the fingerprint identification area of the present embodiment is patterned to form a plurality of first fingerprint electrodes 1223 a. The second touch electrode 1222 of the fingerprint identification area is patterned to form a plurality of second fingerprint electrodes 1223 b. Because the first touch electrode 1221 and the second touch electrode 1222 are arranged in an insulating and intersecting manner, the first fingerprint electrode 1223a and the second fingerprint electrode 1223b formed by patterning the first touch electrode 1221 and the second touch electrode 1222 are also arranged in an insulating and intersecting manner, and a capacitor for fingerprint identification is conveniently formed at the intersecting and overlapping position. The arrangement form of the first fingerprint electrodes 1223a and the second fingerprint electrodes 1223b and the arrangement form type of the first touch electrodes 1221 and the second touch electrodes 1222 are the same, that is, the first touch electrodes 1221 may be parallel or not parallel to each other, and the second touch electrodes 1222 may be parallel or not parallel to each other, as long as they cross to form a capacitor that can be used for fingerprint recognition.
In this embodiment, the display panel 100 may further include a plurality of first switches (not shown) and a plurality of second switches (not shown). Each first fingerprint electrode 1223a in the same first touch electrode 1221 is electrically connected through a first switch. If the first switches are turned on, the first fingerprint electrodes 1223a in the same first touch electrode 1221 are shorted to have the same potential, and at this time, the first touch electrode 1221 can implement a touch function. If the first switches are turned off, the first fingerprint electrodes 1223a in the same first touch electrode 1221 are turned off and may have different potentials, and at this time, the first fingerprint electrodes 1223a in the first touch electrode 1221 may implement a fingerprint identification function.
Similarly, the second fingerprint electrodes 1223b in the same second touch electrode 1222 are electrically connected through the second switch. If the second switches are turned on, the second finger electrodes 1223b in the same second touch electrode 1222 are shorted to have the same potential, and the second touch electrode 1222 can perform a touch function. If the first switches are turned off, the second fingerprint electrodes 1223b in the same second touch electrode 1222 are turned off and may have different potentials, and the second fingerprint electrodes 1223b in the second touch electrode 1222 may perform a fingerprint recognition function. Therefore, the switching between the touch control and the fingerprint identification function can be simply realized through the on-off of the first switch and the second switch.
In this embodiment, the touch sub-layer group 122 may be entirely located on one side of the package layer 121. The touch sub-layer group 122 includes a first touch layer 122a, a touch insulating layer 122b, and a second touch layer 122c sequentially stacked. Therefore, the first touch layer 122a and the second touch layer 122c are insulated and separated by the touch insulating layer 122 b. The plurality of first touch electrodes 1221 are disposed on the first touch layer 122 a. The second touch electrodes 1222 are disposed on the second touch layer 122c, and are insulated and spaced at the intersection of the first touch electrode 1221 and the second touch electrode 1222, so as to form a touch capacitor. Meanwhile, the first touch electrode 1221 and the second touch electrode 1222 are respectively disposed on two touch layers (the first touch layer 122a and the second touch layer 122c) that are insulated and separated from each other. Therefore, the first fingerprint electrodes 1223a with fine structures can be formed on the first touch layer 122a layer at one time, and the second fingerprint electrodes 1223b with fine structures can be formed on the second touch layer 122a layer at one time, so as to facilitate fine patterning control.
Specifically, the touch sub-layer group 122 may be disposed on a side of the package layer 121 away from the display layer group 110 (refer to fig. 2), so as to be beneficial to sealing each sub-pixel in the display layer group 110. Of course, in other embodiments, the touch sub-layer group 122 may also be disposed on a side of the package layer 121 close to the display layer group 110.
Meanwhile, the package layer 120 of the present embodiment further includes a touch connection line 123 and a fingerprint connection line 124. The touch connection line 123 is used for transmitting a touch signal. Specifically, the touch connection line 123 includes a plurality of lines, and a portion of the touch connection line 123 is connected to the first touch electrode 1221, and a portion of the touch connection line 123 is connected to the second touch electrode 1222, so as to transmit the touch signal. The fingerprint connecting line 124 is used for transmitting fingerprint identification signals. Specifically, the fingerprint connecting line 124 includes a plurality of lines, and a portion of the fingerprint connecting line 124 is connected to the first fingerprint electrode 1223a, and a portion of the fingerprint connecting line 124 is connected to the second fingerprint electrode 1223b, so as to perform fingerprint identification signal transmission.
The touch connection line 123 and the fingerprint connection line 124 are located on a side of the package layer 121 away from the display layer group 110. That is, the touch connection line 123, the fingerprint connection line 124 and the touch sub-layer group 122 are located on the same side of the display layer group 110, thereby facilitating circuit layout. Referring to fig. 4, the display panel 100 of the present embodiment further includes a first circuit board 130. The first circuit board 130 is electrically connected to the touch connection line 123 and the fingerprint connection line 124.
In this embodiment, the first circuit board 130 integrates the touch control function and the fingerprint recognition control function, so as to reduce the total number and volume of the circuit boards and save the cost of the circuit boards. Meanwhile, the display layer group 110 usually has a display connection line 114 for connecting and transmitting display signals (data signals, scan signals, etc.). At this time, the display panel may further include a second circuit board 140 electrically connected to the display connection line 114, thereby implementing display function control. The first circuit board 130 and the second circuit board 140 may be flexible circuit boards.
In this embodiment, the touch connection line 123 and the fingerprint connection line 124 may be collinear (i.e., the fingerprint connection line 124 is a component of the touch connection line 123), so as to simplify the circuit design and save the peripheral trace area.
At this time, the display panel 100 may be simultaneously set to include a plurality of first switches and a plurality of second switches. The first fingerprint electrodes 1223a in the same first touch electrode 1221 are electrically connected through a first switch, and the second fingerprint electrodes 1223b in the same second touch electrode 1222 are electrically connected through a second switch. At this time, since the touch connection line 123 and the fingerprint connection line 124 are collinear, the first switch and the second switch can be disposed on the first circuit board 130.
Of course, in this embodiment, the first switch and the second switch may also be disposed at other positions, such as between the fingerprint connection lines 124 on the package layer 121, which is not limited in this application. In other embodiments of the present disclosure, the touch connection line 123 and the fingerprint connection line 124 may not be collinear, and the first switch and the second switch may be disposed between the fingerprint identification electrodes 1223.
Second embodiment
Referring to fig. 5, unlike the above-mentioned scheme of disposing the touch sub-layer group 122 on a certain side of the package layer 121, the first touch layer 122a is disposed on a side of the package layer 121 away from the display layer group 110, and the second touch layer 122c is disposed on a side of the package layer 121 close to the display layer group 110. In the present embodiment, the encapsulation layer 121 is used as an insulating layer, thereby saving additional steps of depositing a touch insulating layer. Meanwhile, the thickness of the encapsulation layer 121 is generally thicker, which can also effectively increase the distance between the first touch electrode 1221 and the second touch electrode 1222, thereby reducing the coupling capacitance between the first touch electrode 1221 and the second touch electrode 1222 and surrounding circuits, thereby improving the sensitivity and user experience.
In the present embodiment, referring to fig. 6, the package layer group 120 includes a touch connection line 123 for transmitting a touch signal and a fingerprint connection line 124 for transmitting a fingerprint identification signal. The display layer group 110 includes touch docking pins 115 for transmitting a touch signal and fingerprint docking pins 116 for transmitting a fingerprint identification signal. Meanwhile, the display panel 100 includes a first circuit board 130.
The touch connecting lines 123 include a first touch connecting line 1231 and a second touch connecting line 1232. The first touch connection line 1231 is disposed on the first touch layer 122a, and is specifically connected to the first touch electrode 1221 for transmitting a touch signal. The second touch connection line 1232 is disposed on the second touch layer 122c, and is specifically connected to the second touch electrode 1222 to transmit the touch signal. In fig. 6, the solid lines and the dotted lines respectively indicate that the first touch layer 122a of the package layer 121 on the side away from the display layer group 110 is disposed and the second touch layer 122c of the package layer 121 on the side close to the display layer group 110 is disposed.
The touch docking pin 115 is connected to the second touch connection line 1232 through a conductive adhesive, and the fingerprint docking pin 116 is connected to the second fingerprint connection line 1242 through a conductive adhesive.
The first circuit board 130 is electrically connected to the first touch connection line 1231, the first fingerprint connection line 1241, the touch docking pin 115, and the fingerprint docking pin 116, so as to implement a touch control function and a fingerprint identification control function. Specifically, the first touch connection line 1231 and the first fingerprint connection line 1241 on the upper side of the package layer 121 (i.e., the side away from the display layer group 110) may be bonded to the first circuit board through conductive paste. The touch docking pins 115 and the fingerprint docking pins 116 on the lower side of the package layer 121 (i.e., the side far away from the display layer group 110) may be bonded to the first circuit board through a conductive adhesive.
Meanwhile, the display layer group 110 usually has a display connection line 114 for connecting and transmitting display signals (data signals, scan signals, etc.). At this time, the display panel may further include a second circuit board 140 electrically connected to the display connection line 114, thereby implementing display function control. Alternatively, the first circuit board 130 may also be electrically connected to the display connection line 114, the touch connection line 123, and the second fingerprint connection line 124, so as to integrate the display control function, the touch control function, and the fingerprint identification control function.
In the embodiment of the present application, a local area of the touch sub-layer 122 is a fingerprint identification area. The fingerprint identification area is located at the edge of the display panel 100, so that the fingerprint connection line 124 is electrically connected to the fingerprint identification electrode 1223 in the fingerprint identification area. Of course, the present application is not limited thereto, and the fingerprint identification area may be located at a non-edge middle position.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
