The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
Example one
Fig. 1 is a schematic structural diagram of a display module according to a first embodiment of the present application, and referring to fig. 1, the display module includes a first display panel 110 and a second display panel 120, and the first display panel 110 and the second display panel 120 both have a light exit side and a light entrance side opposite to each other in a thickness direction thereof. Wherein the first display panel 110 and the second display panel 120 are stacked in a thickness direction. Specifically, the first display panel 110 is located at the light emitting side of the second display panel 120; one side of the first display panel 110 close to the second display panel 120 is a light incident side, and one side far away from the second display panel 120 is a light emergent side; one side of the second display panel 120 close to the first display panel 110 is a light emitting side thereof, and one side far away from the first display panel 110 is a light emitting side thereof.
The first display panel 110 may be a liquid crystal display panel (i.e., LCD), and the first display panel 110 includes a first polarizing film 111, a first opposite substrate 114, a first liquid crystal layer 113, and a first array substrate 112, which are sequentially disposed from a light-emitting side to a light-entering side thereof. The first array substrate 112 includes a first opposite region 1121 opposite to the first opposite substrate 114 and a first external lead region 1122 on at least one side of the first opposite region 1121, and the first external lead region 1122 may be used to bind the first driving unit 115. The first external lead region 1122 is provided with leads connected to the first driving unit 115, which is a non-display region.
In order to facilitate the binding of the first driving unit 115, the first external lead region 1122 of the first array substrate 112 may be protruded with respect to the first opposite substrate 114.
The second display panel 120 may also be a liquid crystal display panel, and the second display panel 120 includes a second polarizing film 121, a second array substrate 122 and a second liquid crystal layer 123, which are sequentially disposed from the light incident side to the light emitting side. The second array substrate 122 correspondingly includes a second opposite region 1221 and a second external lead region 1222 positioned at least one side of the second opposite region 1221, and the second external lead region 1222 is used for binding the second driving unit 125. The second external lead area 1222 is provided with a lead connected to the second driving unit 125, which is a non-display area.
In order to facilitate the bonding of the second driving unit 125, the width of the second external lead region 1222 of the second array substrate 122 may be greater than the width of the first external lead region 1122 of the first array substrate 112, such that the second external lead region 1222 of the second array substrate 122 is protruded with respect to the first external lead region 1122 of the first array substrate 112.
It should be noted that the first opposing substrate 114 may be a color film substrate, and the color film substrate includes a substrate and a color film layer formed on the substrate; the first array substrate 112 and the second array substrate 122 each include a substrate and a TFT (thin film transistor) array layer formed on the substrate; the substrate base plates of the first opposite base plate 114, the first array base plate 112 and the second array base plate 122 are all glass base plates.
In this embodiment, two liquid crystal display panels are stacked to realize true double contrast and double color display, and the brightness and the chromaticity are closer to the true human vision, and can be compared with the OLED in image quality, but the first external lead area 1122 and the second external lead area 1222 are provided with leads, which are non-display areas and are both located on the light emitting side, so that a front bezel needs to be manufactured to shield the first external lead area 1122 and the second external lead area 1222, which is not favorable for realizing a narrow bezel.
Example two
Fig. 2 is a schematic structural diagram of a display module according to a second embodiment of the present application, and referring to fig. 2, the display module includes a first display panel 110 and a second display panel 120, the first display panel 110 and the second display panel 120 are stacked in a thickness direction, and the first display panel 110 is located on a light emitting side of the second display panel 120.
The first display panel 110 may be a liquid crystal display panel, and the first display panel 110 includes a first polarizing film 111, a first array substrate 112, a first liquid crystal layer 113, and a first opposite substrate 114. The first array substrate 112 is located on a side of the first opposite substrate 114 away from the second display panel 120, the first polarizing film 111 is disposed on a side of the first array substrate 112 away from the second display panel 120, and the first liquid crystal layer 113 is disposed between the first array substrate 112 and the first opposite substrate 114, that is: the first polarizing film 111, the first array substrate 112, the first liquid crystal layer 113, and the first opposite substrate 114 are sequentially disposed from the light-emitting side to the light-entering side of the first display panel 110. The first array substrate 112 includes a first opposite region 1121 opposite to the first opposite substrate 114 and a first external lead region 1122 on at least one side of the first opposite region 1121.
It should be understood that, in the first display panel 110, the first external lead region 1122 and the first opposite region 1121 are arranged in a horizontal direction, which is perpendicular to the thickness direction of the first display panel 110.
For example, the first opposite substrate 114 may be a color filter substrate, and the color filter substrate includes a substrate, and a color filter layer, a black matrix, and a liner formed on the substrate. The first array substrate 112 includes a base substrate and a TFT array layer formed on the base substrate, and it is to be understood that a pixel electrode, an alignment layer, and the like may be further disposed on the base substrate.
It should be noted that the Color film layer is not limited to be disposed on the first opposite substrate 114, and may also be manufactured by using a COA (Color-filter on Array) technique, that is: the color film layer is directly manufactured on the array substrate according to the situation. The substrate substrates of the first opposite substrate 114 and the first array substrate 112 may be glass substrates, but are not limited thereto, and may also be PI (polyimide) substrates as the case may be.
In the present embodiment, the first array substrate 112 of the first display panel 110 may be understood as being located at the light-emitting side, and the opposite first opposite substrate 114 may be understood as being located at the light-entering side, that is: it is understood that the first array substrate 112 is inverted, and the leads of the first external lead region 1121 thereof can be understood to be located on the side of the substrate facing the first opposing substrate 114 due to the inversion of the first array substrate 112, so that the leads of the first external lead region 1122 can be shielded by the first array substrate 112 itself, and thus a narrow frame or no frame can be achieved.
Referring to fig. 2, the second display panel 120 may also be a liquid crystal display panel, and the second display panel 120 includes: a second polarizing film 121, a second array substrate 122, and a second liquid crystal layer 123. The second liquid crystal layer 123 is disposed between the first opposite substrate 114 and the second array substrate 122 of the first display panel 110, and the second polarizing film 121 is disposed on a side of the second array substrate 122 away from the first display panel 110.
That is, in the present embodiment, the first display panel 110 and the second display panel 120 may share an opposite substrate, that is: the first opposite substrate 114 is designed to reduce one substrate, so that the thickness of the display module can be reduced, and the production cost can be reduced.
It should be noted that the second array substrate 122 includes a substrate and a TFT array layer formed on the substrate, and it should be understood that the substrate may also be provided with a pixel electrode, an alignment layer, and other structures. The substrate of the second array substrate 122 may be a glass substrate, but is not limited thereto, and may also be a PI (polyimide) substrate, as the case may be.
In the second display panel 120, the second array substrate 122 includes a second opposite region 1221 and a second external lead region 1222 positioned at least one side of the second opposite region 1221. It should be understood that, in the second display panel 120, the first external lead area 1222 and the first opposite area 1221 are arranged in a horizontal direction, which is perpendicular to the thickness direction of the second display panel 120.
Wherein an orthogonal projection of the second external lead region 1222 on the first array substrate 112 is located within the first external lead region 1122 or coincides with the first external lead region 1122. So set up, second external lead area 1222 can be sheltered from by first external lead area 1122 completely, need not make the front bezel shelter from second external lead area 1222 to narrow frame or no frame can be accomplished.
Referring to fig. 2, a first driving unit 115 is bound to a side of the first external lead region 1122 close to the second display panel 120, and the first driving unit 115 drives the first display panel 110 for displaying; a second driving unit 125 is bonded to a side of the second external lead region 1222 near the first opposite substrate 114, and the second driving unit 125 drives the second display panel 120 for controlling light. The two driving units are arranged between the first array substrate 112 and the second array substrate 122, and a frame does not need to be manufactured to shield the two driving units, so that a narrow frame or no frame can be realized.
In addition, fig. 3 is a schematic diagram of a driving unit side binding of a display module according to a first embodiment of the present disclosure, and referring to fig. 3, in some embodiments, a first driving unit 115 is bound to a side of the first external lead region 1122 away from the first opposite region 1121, and a second driving unit 125 is bound to a side of the second external lead region 1222 away from the second opposite region 1221, so that the area of the opposite region can be increased appropriately, the light transmission area can be increased appropriately, and the display area can be increased accordingly.
The first array substrate 112 may be generally understood to include a light emitting surface far away from the second display panel 120, a light incident surface near the second display panel 120, and a side surface connecting the light emitting surface and the light incident surface, and the first driving unit 115 is disposed on the side surface of the first array substrate 112 and electrically connected to the leads of the first external lead region 1122. Accordingly, the second array substrate 122 can be understood as including a light emitting surface, a light incident surface and a side surface, and the second driving unit 125 is disposed on the side surface of the second array substrate 122 and electrically connected to the leads of the second external lead region 1222. The first driving unit 115 is disposed at the side of the first array substrate 112, the second driving unit 125 is disposed at the side of the second array substrate 122, and the two driving units can be shielded by a frame, and since the thicknesses of the first driving unit 115 and the second driving unit 125 are relatively small, even if the frame shielding is required, the size of the frame can be designed to be relatively narrow, that is: the narrow frame can be achieved by the embodiment.
In this embodiment, the two liquid crystal display panels are overlapped, light emitted from the backlight side is converted into linearly polarized light through the second polarizing film 121, then the light is converted into elliptically polarized light through the second liquid crystal layer 123 and the first liquid crystal layer 113, and then the light is converted into linearly polarized light through the first polarizing film 111, so that the display picture can be observed at the light emitting side, but the light path between the two liquid crystal layers is twice of that of a single-layer display module, so that serious color cast can be caused, and the image quality of the double-layer panel display module is influenced.
In order to avoid color shift, referring to fig. 2, the display module may further include a third polarizing film 140, where the third polarizing film 140 is disposed between the first display panel 110 and the second display panel 120, and particularly, may be disposed on a side of the first opposing substrate 114 away from the first array substrate 112, but is not limited thereto, and may also be disposed on a side of the first opposing substrate 114 close to the first array substrate 112, as the case may be.
In this embodiment, the third polarizing film 140 is disposed between the first display panel 110 and the second display panel 120, and the deflection of the third polarizing film 140 is utilized to adjust the optical path difference to be the same as that of the single-layer display module, so that the color shift is avoided, and the image quality of the double-layer panel display module is greatly improved.
EXAMPLE III
Fig. 4 is a schematic structural diagram of a display module in the third embodiment of the present application, and referring to fig. 4, the main differences between the display module in the third embodiment and the display module in the second embodiment are as follows: in the third embodiment, the second display panel 120 further includes a second opposite substrate 124, that is, the second display panel 120 does not share the first opposite substrate 114 of the first display panel 110, but additionally provides an opposite substrate, that is: and a second opposite substrate 124.
In this embodiment, the second array substrate 122 may include a second opposite region 1221 and a second external lead region 1222 positioned at least one side of the second opposite region 1221. The second opposite substrate 124 is disposed opposite to the second opposite region 1221, and the second opposite substrate 124 is disposed between the second array substrate 122 and the first opposite substrate 114, that is: the second polarizing film 121, the second array substrate 122, the second liquid crystal layer 123, and the second opposite substrate 124 are sequentially disposed from the light-in side to the light-out side of the second display panel 120 itself.
It should be noted that the second opposite substrate 124 may be a color film substrate, and the color film substrate includes a substrate, and a color film layer, a black matrix, and a liner formed on the substrate. However, the color film layer is not limited to be disposed on the second opposite substrate 124, and may also be fabricated by using COA technology, where the color film layer is directly fabricated on the second array substrate 122, as the case may be.
