Embodiment 1
[0045] Embodiment 1: the arrangement of the first light collimation member 410 .
[0046] In specific implementation, in the above-mentioned display device provided by the embodiment of the present invention, the display panel 100 can specifically adopt the following Figure 4a to Figure 4d The electroluminescent display panel shown can also be used as Figure 5a to Figure 5b The LCD panel shown.
[0047] When the display panel adopts an electroluminescence display panel, such as Figure 4a to Figure 4d As shown, the display panel 100 specifically includes: a base substrate 110, a pixel control circuit device 120 disposed on the base substrate 110, a plurality of light emitting elements 130 disposed on the pixel control circuit device 120, and a cover light emitting element 130 The encapsulation film 140; wherein, the pixel control circuit device 120 is composed of a plurality of thin film transistors, and only one thin film transistor is schematically shown in the figure. ...
Embodiment 2
[0059] Embodiment 2: the arrangement of the second light collimation member 420 .
[0060] When the display panel adopts an electroluminescence display panel, in the above-mentioned display device provided by the embodiment of the present invention, as Figure 4a to Figure 4d As shown, the second light collimating member 420 may include: one or a combination of the gate film layer 121 and the source-drain film layer 122 in the pixel control circuit device 120, and the anode layer 131 in the light emitting element 130 is arranged in the same layer The light-shielding member has a light-shielding area in the non-light-emitting area where the photosensitive device 300 is disposed, and has a light-transmitting area above the photosensitive device 300 .
[0061] exist Figure 4a with Figure 4b shows a case where a light-shielding component is set in the same layer as the source-drain film layer 122, in Figure 4c shows the case where two light-shielding components are respectiv...
Embodiment 3
[0064] Embodiment 3: The photosensitive device 300 is disposed in the non-display area of the display panel 100 .
[0065] Furthermore, when the photosensitive device 300 is arranged in the non-light-emitting area of the display area of the display panel 100, the light-shielding area B must not be set in the opening area of the pixel unit Pixel by the light-collimating member 400, so it is inevitable that stray light will be incident to the photosensitive device 300 . In the case of a high requirement for the definition of texture recognition, during specific implementation, in the above-mentioned display device provided by the embodiment of the present invention, the photosensitive device may also be arranged in the non-display area of the display panel.
[0066] Taking the liquid crystal display panel as an example for the display panel, in the above-mentioned display device provided by the embodiment of the present invention, as Figure 5b As shown, the first lig...
