In an alternative embodiment, the second display panel 2 further comprises a second operating state in which the second display panel 2 overlaps the first display panel 1 in a first direction X, the first direction X being the direction from the first display panel 1 to the second display panel 2.

Specifically, with continued reference to fig. 1, the second display panel 2 further includes a second operating state, where the second operating state may be an undeployed state of the second display panel 2, and in the undeployed state of the second display panel 2, along the first direction X, the second display panel 2 overlaps the first display panel 1, which may be understood that the second display panel 2 covers the first display panel 1, and in the undeployed state of the second display panel 2, the second display panel 2 may display other graphics to achieve a similar effect of beautifying and decorating on a mobile phone casing.

It should be noted that: fig. 4 is a semi-unfolded state of the second display panel 2 between the first working state and the second working state, when the display device includes a housing 6, the second display panel 2 and the housing 6 may be rotated, and when the second display panel 2 rotates above the first display panel 1, the display surfaces of the first display panel 1 and the second display panel 2 are on the same side after being unfolded, as shown in fig. 3; when the second display panel 2 is in the undeployed state, a double-sided display can be realized, as shown in fig. 1; of course, according to practical situations, other manners may be used between the second display panel 2 and the housing 6, for example, a sliding manner may be used between the second display panel 2 and the housing 6, and a double-sided display may be also realized, which is not limited in this embodiment.

Of course, according to the actual situation, the third working state and the fourth working state may be two states, and the states opened by the two states are different, so that the difference between the first transmittance and the second transmittance can be realized, thereby controlling the transparency of the second display panel 2.

It should be noted that, the driving unit 231 may be transparent or translucent, and even if the driving unit is of a translucent structure, only the position where the electronic components are disposed is opaque, and the gaps between the electronic components are still transparent, thereby reducing the shielding of the upper light emitting chip.

Alternatively, as shown in fig. 5, when the second display panel 2 is in the undeployed state and the light valve 4 is in the closed state, for example, the first transmittance is low, for example, the low transmittance may be lower than 20%, so that the second display panel 2 becomes a non-transparent screen, which can be understood that the second display panel 2 is a normal display screen. If the display device includes the housing 6, the decorative pattern is printed on the back of the housing 6, when the second display panel 2 is in the undeployed state and the light valve 4 is in the opened state, if the second transmittance is high, the high transmittance may be higher than 70%, the decorative pattern on the back of the housing 6 and the image displayed on the second display panel 2 are superimposed together, and the display effect of the display module is further improved by the superimposed picture.

Specifically, as shown in fig. 7 and 8, the camera assembly 3 includes a camera 31, the camera 31 may collect second data, the second data may be image or video data, an opening 41 is formed on the light valve 4, the opening 41 penetrates through the light valve 4 in the first direction X, and the front projection of the camera 31 on the plane of the first display panel 1 overlaps with the front projection of the opening 41 on the plane of the first display panel 1, so as to avoid shielding the camera 31, thereby being beneficial to the camera 31 to collect the second data, alternatively, the front projection of the camera 31 on the plane of the first display panel 1 is located within the front projection of the opening 41 on the plane of the first display panel 1, and being more beneficial to the camera 31 to collect the second data; of course, according to practical situations, the front projection of the camera 31 on the plane of the first display panel 1 only partially overlaps with the front projection of the opening 41 on the plane of the first display panel 1, so as to reduce the shielding of the camera 31 as much as possible, and avoid affecting the camera 31 to collect the second data as much as possible.

In an alternative embodiment, with continued reference to fig. 1, the resolution of the first display panel 1 is higher than the resolution of the second display panel 2, which refers to the number of display pixels per unit area, and the transparency of the second display panel 2 is increased by decreasing the resolution of the second display panel 2.

Alternatively, as shown in fig. 1, with continued reference to fig. 1, the pixel density of the first display panel 1 is higher than the pixel density of the second display panel 2, the pixel density representing the number of pixels per inch, the transparency of the second display panel 2 is increased by decreasing the pixel density of the second display panel 2; for example, the pixel density of the first display panel 1 may be 300PPI to 450PPI, and the pixel density of the second display panel 2 may be 100PPI to 200PPI.

In an alternative embodiment, as shown in fig. 1, the thickness of the second display panel 2 is not smaller than the thickness of the first display panel 1, so that the mechanical performance between the second display panel 2 and the housing 6 is improved when the display module is fixed on the housing 6, by the thickness of the second display panel 2 being not smaller than the thickness of the first display panel 1.

In an alternative embodiment, with continued reference to FIG. 1, the second display panel 2 is any one of a Micro LED display screen, a Mini LED display screen, or an OLED display screen.

The second display panel 2 may also be a Mini LED (sub-millimeter light emitting diode) display screen, and the size of the LED is smaller than 200 μm, and since the Mini LED is smaller than the conventional LED, the light source of the LCD panel can be controlled more precisely, and the LCD panel has higher contrast ratio by combining with a finer Local Dimming technology.

The second display panel 2 may also be an OLED display, where an OLED is a current-type organic light emitting device, and is a phenomenon of emitting light by injection and recombination of carriers, and the light emission intensity is proportional to the injected current. Under the action of an electric field, holes generated by the anode and electrons generated by the cathode of the OLED move, are respectively injected into the hole transmission layer and the electron transmission layer and migrate to the light-emitting layer, and when the hole transmission layer and the electron transmission layer meet at the light-emitting layer, energy excitons are generated, so that light-emitting molecules are excited to finally generate visible light.

It should be noted that: the second display panel 2 may also be an LED display screen, and since the Micro LED display screen has advantages of high brightness, wide color gamut, long service life, quick response, and the like, compared with the LED display screen and the OLED display screen, when the display module is applied to a vehicle, since the Micro LED is smaller than 100 μm and does not need a packaging structure of a polarizing film, the transparency of the Micro LED display screen has unique advantages compared with the LED display screen, the Mini LED display screen, and the OLED display screen.
