Structure, such as hole transmission layer, electron transfer layer, electronic barrier layer, hole blocking layer etc..It is formed by the light-emitting component 12
Display component be top light emitting structure, certainly can also be according to different uses and flexible setting is bottom light emitting structure, two-sided hair
Photo structure.
In above-mentioned display component 100, according to the control of driving circuit and TFT thin film transistor (TFT) 112, it can be achieved that the member that shines
The independent control of part 12, i.e., one or more light-emitting components 12 are lighted.In addition, the light-emitting component 12 is for issuing same color
Optical signal, such as white, black；The optical signal of different colours, such as red, blue, green, yellow etc. can also be issued.
Further, layer please is collimated due to will be arranged above the sensor devices Q1 of photosensitive pixel 220 in conjunction with referring to Fig. 6
24 collimation part 240, and collimating part 240 is extinction structure, therefore in order to not influence the normal display of display component 100, sense
The sensor devices Q1 of light pixel 220 is necessarily placed above non-display area L2.In addition, due to switching device Q2 area compared with
It is small, therefore switching device Q2 is arranged in the L1 of display area, will not influence very much the display effect of display component 100.Certainly, it is
Reach better display effect, preferably by the structure setting of photosensitive pixel 220 above non-display area L2.It is understood that
It is that, if the device in photosensitive pixel 220 is transparent configuration, which also can be set in the display area of display component 100
In L1, such as the sensor devices Q1 of transparent configuration.It should be noted that display pixel includes tri- kinds of display pictures of R, G, B in Fig. 6
Element, it is not limited to which there are also other display pixels.Here display pixel can also refer to including in tri- kinds of display pixels of R, G, B
One or more.Moreover, the merely illustrative explanation of the arrangement architecture of the display pixel, it is not limited to which there are also other arrangement knots
Structure.
In some embodiments, in the processing procedure of above-mentioned display module 1, can structure as described above be respectively formed
Then package assembling 200 and display component 100 recycle package assembling 200 to be packaged display component 100.Certainly, may be used
With formed package assembling 200 part-structure after, just progress display component 100 encapsulation.For example, first on encapsulation cover plate 21
After sequentially forming photosensitive layer 22 and touch control layer 23, the encapsulation cover plate 21 for forming photosensitive layer 22 and touch control layer 23 is used to encapsulate display
