Specifically, the first display panel 2 may be an OLED organic light emitting display panel, i.e. having advantages of self-luminescence, high brightness, good display effect, etc., for example, the first display panel may include a plurality of light emitting pixels, each of which includes at least two color sub-pixels and a pixel driving circuit, such as a red sub-pixel, a green sub-pixel and a blue sub-pixel; the drive circuitry for driving the emissive pixels may be thin film transistors, such as the 2T1C, 7T1C circuits. Of course, other display panels, such as a liquid crystal display panel, a plasma display panel, a CRT display panel, or a Micro-LED display panel, etc. may be used. The projection area 22 may be transparent, transparent or non-transparent, for example, a common non-display area such as a camera area or a frame area; the particular location of the projection area 22 is not a particular requirement of the present invention.
The display module further comprises a light-extracting module 200, wherein the light-extracting module 200 is arranged corresponding to the projection area 22; the light-extracting module comprises a camera, a fingerprint sensor and an iris sensor, and can meet the functional requirements of image acquisition, fingerprint identification and the like.

More specifically, the display device 100 further includes a cover plate 1 disposed on a light-emitting surface side of the first display panel 2, the cover plate 1 being transparent to protect the light-emitting display panel, and a housing 5.

The display module further includes a projection module 4, and the projection module 4 is configured to project the second display image to the projection area 22, so that the projection area can correspondingly display the second image. For example, the projection module 4 may be located between the first display panel 2 and the housing 5, the projection area 22 may not overlap with the second display panel 3 in the front projection direction of the first display panel 2, and is disposed corresponding to the second display panel 3, and may project the second display image to the projection area 22, so that the first display image displayed by the first display panel 2 and the second display image displayed by the second display panel 3 may form a substantially continuous image, or the second display image displayed by the second display panel 3 serves as an auxiliary display, so as to meet the requirement that the projection area 22 serves as a functional area.
In a possible embodiment, the projection area 22 includes a first state and a second state, in the first state, the projection area 22 displays a second display image projected by the projection module 4, for example, when the display module needs to perform normal display, the second display panel 3 projects information that needs to be displayed in the projection area 22 through the projection module 4, so as to achieve a function of normal display; in the second state, the projection area 22 no longer displays the second display image, and the light-capturing module 200 captures light rays emitted from the projection area 22 to capture the image, for example, when the display module needs to capture light rays, the projection module 4 is turned off, so that the projection area 22 does not have light-emitting pixels, and thus the light transmittance is very high, and the light-capturing module 200 captures required optical information through the projection area 22 without interference.
Specifically, the second display panel 3 can switch the working state according to the on and off of the light extraction module 200.

When the detection module detects that the light-taking module 200 is in the non-working state and the closed state, the driving control module drives the second display panel 3 to be switched to the first state for displaying, and controls the projection module 4 to adjust the projection mode, so that the second display image is better projected to the projection area 22, and full-screen display is realized; when the detection module detects that the light-extracting module 200 is in the working state and the open state, the driving control module drives the second display panel 3 to switch to the second state, so that the light-extracting module 200 collects the light rays shot from the projection area 22 for image collection.
According to the display module and the display device provided by the embodiment of the invention, the second display panel separated from the first display panel is arranged, and the projection module is utilized to project the picture displayed by the second display panel to the projection area of the first display panel, so that the effect that the display can be realized in the non-display area of the traditional display panel is achieved, the screen occupation ratio of the display screen is increased, and compared with the traditional implementation mode, the following difficulties are overcome:
the existing light-transmitting area is used for increasing the light transmittance, the pixel driving circuit is arranged in the non-display area, the light-emitting pixels are reserved in the projection area (the light-transmitting area), but the area of the non-display area is limited, so that the setting quantity of the pixel driving circuit is limited, the higher screen occupation ratio is prevented from being obtained, if the distance between the pixel driving circuit and the light-emitting pixels is far away, the problem of the overlarge impedance and uneven display is caused, and the problem of light diffraction is caused due to the regular shading of the light-emitting pixels, and the image collected by the light-taking module is blurred. On the other hand, the density of the light-emitting pixels reserved in the projection area (light-transmitting area) is low, and the pixels can be deformed in corresponding shapes or sizes, so that the brightness of the pixels is increased during normal display to make up for the brightness difference with the normal display area, and thus the aging of the light-emitting pixels reserved in the projection area (light-transmitting area) is accelerated, and the problem of non-uniform display is caused.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
