The second substrate 2 includes sensor groups 21 corresponding to at least some of the light emitting units 11 one to one, and the sensor groups 21 include first optical sensors 211 and second optical sensors 212.
The orthographic projection of the first optical sensor 211 on the first substrate 1 is located in the display light-emitting area a and is used for detecting the light L of the display light-emitting area aAAnd an external light L passing through the display light emitting region Ain。
The orthographic projection of the second optical sensor 212 on the first substrate 1 is positioned in the non-display light-emitting area B and is used for detecting the light L of the non-display light-emitting area BB。
Specifically, as shown in fig. 2, the display light-emitting area a refers to the light L emitted by the light-emitting unit 11AThe non-display light-emitting region B is a region where light emitted from the light-emitting unit 11 is blocked and cannot be emitted to the outside of the display panel; it can be known from the reversibility of the optical path that the display light-emitting region a can also let in external light, and the non-display light-emitting region B cannot let in external light, so that the non-display light-emitting region B is not affected by external light.
The present example provides a displayA display panel for displaying light of the light emitting region A and external light L passing through the light emitting region A by dividing the light emitting unit 11 corresponding to the sub-pixel SP into a display light emitting region A and a non-display light emitting region B and providing a first optical sensor 211 and a second optical sensor 212 corresponding to the display light emitting region A and the non-display light emitting region B, respectivelyinThe light L of the non-display light-emitting region B, which can be collected by the first optical sensor 211BLight that can be collected by the second optical sensor 212 while the same light-emitting unit 11 displays the light-emitting region a and the non-display light-emitting region B has substantially the same characteristics. Therefore, the data collected by the two optical sensors can be used for calculating external light data, the external light data can be converted into corresponding operation instructions through data processing, and the operation instructions can control the display panel to display corresponding pictures, namely the display panel provided by the embodiment can be controlled through a non-contact mode, so that a user can operate the display device through the non-contact mode, and the diversity and the interestingness of man-machine interaction are improved.
Although the non-display light-emitting region B is shown on the left side of the display light-emitting region a in fig. 1, in practice, the non-display light-emitting region B may be located on multiple sides of the display light-emitting region a: specifically, the non-display light-emitting region B is located on adjacent two sides of the display light-emitting region a (e.g., on the left and upper sides of the display light-emitting region a), on opposite sides (e.g., on the left and right sides of the display light-emitting region a), on three sides (e.g., on the left, upper and lower sides of the display light-emitting region a), or surrounds the display light-emitting region a.
With continued reference to fig. 2, it should be noted that the light L of the display light-emitting area detected by the first optical sensor 211ANot all the light of the light emitting area A but the light L of the light emitting area AAMost of them are capable of exiting the display panel for display; the second optical sensor 212 detects the light L in the non-display light-emitting region BBThe light L in the non-display light-emitting area B is not the whole light in the non-display light-emitting area ABAnd a part of the second light is absorbed by other structures or cannot be reflected, refracted and scattered by the second lightThe optical sensor 212 detects.
Referring to fig. 3, optionally, in the display panel provided in this embodiment, the light emitting unit 11 includes: an anode layer 111, an organic light emitting layer 112, and a cathode layer 113; the anode layer 111 has light permeability; the organic light emitting layer 112 covers the anode layer 112 and is located in the display light emitting region a and the non-display light emitting region B; the cathode layer 113 covers the organic light emitting layer 112 and has light transmittance. Specifically, the display panel in this embodiment is an organic light emitting display panel, and the material of the anode layer 111 is usually Indium Tin Oxide (ITO) to ensure that the light emitted from the light emitting unit 11 can exit the display panel through the anode layer 111, and the organic light emitting layer 112 can also transmit the light. Therefore, by providing the anode layer 111 and the cathode layer 113 with light permeability, the light L in the light emitting region a can be displayedAExternal light LinThe light L passing through the cathode layer 113 having light transmissivity is collected by the first optical sensor 211, and is not emitted to the display light emitting region BBThe light passing through the cathode layer 113 having light transmissivity is collected by the second optical sensor 212.
With reference to fig. 3, further, the thickness of the cathode layer 113 is 5nm to 20nm, the material includes an aluminum metal layer, and the cathode layer may be manufactured by an aluminum metal thinning technique during the manufacturing process; or the thickness of the cathode layer 113 is 50nm to 80nm, and the material includes a magnesium-silver metal layer. Through the materials and the corresponding thickness, the light transmittance of the cathode layer 113 can be controlled to be 5% -10%, and at the moment, the reflectivity of the cathode layer 113 is also high, so that the light can be collected by the first optical sensor 211 and the second optical sensor 212, and the display effect can not be influenced.
Referring to fig. 3, optionally, in the display panel provided in this embodiment, the first substrate 1 further includes a first substrate 12 and a light shielding layer 13: the light shielding layer 13 is positioned on one side of the first substrate 12 close to the second substrate 2 and on one side of the organic light emitting layer far away from the second substrate 2; the light-shielding layer 13 covers the non-display light-emitting region B in an orthographic projection on the second substrate 2. The present embodiment uses the light shielding layer 13 to shield the non-display light emitting region B of the corresponding light emitting unit 11, and can also shield the second optical sensor 212, so that the external light is not collected by the second optical sensor.
With reference to fig. 3, optionally, in the display panel provided in this embodiment, the first substrate 1 further includes a first substrate 12 and a source-drain metal layer 17: the source-drain metal layer 17 is positioned on one side of the first substrate 12 close to the second substrate 2 and on one side of the organic light-emitting layer 112 far away from the second substrate 2; the orthographic projection of the source-drain metal layer 17 on the second substrate 2 covers the non-display light-emitting area B. In the present embodiment, the source/drain metal layer 17 is used to shield the non-display light-emitting region B of the corresponding light-emitting unit 11, so as to shield the second optical sensor 212, so that the external light is not collected by the second optical sensor.
With reference to fig. 3 and 4, no matter the source/drain metal layer 17 is used or the light shielding layer 13 is used to shield the non-display light emitting region B, an additional film layer for shielding light is not required, which is beneficial to simplifying the manufacturing process of the display panel.
Referring to fig. 3 or fig. 4, specifically, the source-drain metal layer 17 includes a source metal 171 and a drain metal 172. The thin film transistor shown in fig. 4 is a top-gate thin film transistor, i.e., a gate layer 16 is formed above an active layer 14, and a gate insulating layer 15 is disposed between the gate layer 16 and the active layer 14. The active layer 14 includes a channel region 141, and a source region 142 and a drain region 143 at both sides of the channel region 141.
The source metal 171 is connected to the source region 141 of the active layer 14, and the drain metal 172 is connected to the drain region 143 of the active layer 14; the source metal 171 is a signal line of the light emitting unit 11 shown in fig. 4, and the drain metal 172 is electrically connected to the anode layer 111 of the light emitting unit 11, so that when an electrical parameter input by the gate layer (gate line) 16 satisfies a conduction requirement of the thin film transistor, the channel region 143 is conducted, so that the source metal 171 and the drain metal 172 are conducted, and an input signal (a driving current or a driving voltage) of the source metal (signal line) 171 is input to the light emitting unit 11, so that the light emitting unit 11 is controlled to emit light with a corresponding driving current or driving voltage.
Although fig. 4 shows a thin film transistor having a top gate structure, a thin film transistor having a bottom gate structure may be used.
Referring to fig. 5, optionally, in the display panel provided in this embodiment, the first substrate 1 further includes a first substrate 12 and a color filter layer 18: the color filter layer 18 is positioned on one side of the first substrate 12 close to the second substrate 2 and on one side of the organic light-emitting layer far away from the second substrate 2; the color filter layer 18 includes a plurality of filter units 181, and the orthographic projection of the filter units 181 on the first substrate 12 covers the orthographic projection of the display light-emitting areas a of the corresponding light-emitting units 11 on the first substrate 12. By providing the color filter layer 18, the organic light emitting layers 112 of the light emitting units 11 can be made of the same material, and the electrical properties of the light emitting units 11 are the same, thereby avoiding the optical sensor acquisition error caused by the difference in the material of the organic light emitting layers 112 and the difference in the electrical properties of the light emitting units 11.
Specifically, the filter unit 181 in the color filter layer 18 corresponds to each light emitting unit, and the filter unit 181 may be divided into a red filter unit, a green filter unit, and a blue filter unit, which correspond to the red sub-pixel (R), the green sub-pixel (G), and the blue sub-pixel (B) in the pixel unit, respectively. In some cases, a white sub-pixel (W) is further included in one pixel unit, and the filter unit 181 corresponding to the white sub-pixel (W) is colorless and transparent, or the filter unit 181 is not required to be disposed at a corresponding position of the white sub-pixel (W).
It should be noted that the present application does not limit the arrangement of the pixels, that is, the pixel units of the display panel provided by the present application may adopt any arrangement manner.
Referring to fig. 6, optionally, in the display panel provided in this embodiment, the first substrate 1 further includes a first substrate 12 and an optical imaging layer 19: the optical imaging layer 19 is positioned on one side of the first substrate 11 far away from the second substrate 2 and comprises a light resistance unit 191, and the light resistance unit 191 is made of infrared light resistance material; the first optical sensor 211 and the second optical sensor 212 are both infrared sensors.

The control method provided by the application can realize human-computer interaction through gesture change. The control method provided by the embodiment of the present application is described by taking a television as an example. The "gesture change" as referred to herein may refer not only to a motion of a hand but also to other motions of a human body, for example, a head motion such as nodding or shaking, a body motion such as turning or tilting of a body in one direction, and the like.
Specifically, in some cases, when a user needs to change channels, adjust volume, or the like, for a television, a corresponding gesture or other action may be made. In other cases, the user may play certain games using the television, and during the playing of these games, the user may make corresponding gestures or other actions to implement certain game operations.
