[0042] figure 2 It is a schematic structural diagram of the display panel according to the first embodiment of the present invention. From figure 1 It can be seen from the figure that the display panel in the embodiment of the present invention includes a substrate 20 and a plurality of depth imaging devices, and each depth imaging device is disposed on the substrate 20 . In order to explain the working principle of the depth camera device in more detail, figure 2Only one depth camera device is shown in . The depth camera device includes a light receiving unit 32 and a collimated light source 31 for emitting parallel light. The display panel also includes a shielding layer 33 disposed between the collimated light source 31 and the measured object 100, the shielding layer 33 is provided with a hollow structure 331, and the light emitted by the collimated light source 31 passes through the hollow structure 331 to form a two-dimensional structured light pattern , the two-di...

[0059] Figure 8 It is a schematic structural diagram of the display panel according to the second embodiment of the present invention. Different from the first embodiment, in this embodiment, if Figure 8 As shown, the display panel further includes a touch electrode layer 51 disposed between the collimated light source 31 and the shielding layer 33 . exist Figure 8 Among them, the touch electrode layer 51 is disposed between the flat layer 34 and the shielding layer 33 . The shielding layer 33 is disposed on the touch electrode layer 51 . It is easy to understand that the touch electrode layer 51 generally includes row electrodes and column electrodes, with gaps between adjacent electrodes. It is easy to understand that the gap between adjacent electrodes includes the gap between adjacent row electrodes, the gap between adjacent column electrodes, and the gap between adjacent row electrodes and column electrodes. In order to ensure that the light emitted by the collima...

Abstract

The invention discloses a display area and a display device. The display panel includes a plurality of depth imaging devices disposed on a substrate and a processor electrically connected to the depthimaging device, the depth imaging device includes a light receiving unit and a collimated light source for emitting parallel light, the display panel further includes a shielding layer disposed between the collimated light source and the object to be measured, the shading layer is provided with a hollow structure, the light emitted by the collimated light source passes through the hollow structure to form a two-dimensional structured light pattern, the light receiving unit receives the reflection pattern of the two-dimensional structured light pattern passing through the object, and the processor obtains the depth information of the object according to the light emitted by the collimated light source and the reflection pattern. The display panel integrates the depth information recognition function and no longer uses the depth camera to obtain the depth information of the object, thus reducing the cost of the display panel and facilitating the lightweight design of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the development of 3D technology, more and more technical applications such as stereoscopic display, machine vision, and satellite remote sensing need to obtain the depth information of the scene. At present, the technical method usually used is to use the depth camera to obtain the depth information of the target in the camera field of view. . [0003] However, the depth camera has the characteristics of large size and high price, so it is difficult to combine with the display products for the purpose of pursuing thinness and lightness. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide a display panel and a display device to solve the problems of high cost of identifying depth information of the display panel and the inability to realize lig...
