The invention provides a display screen, a display device and a display method, wherein the display screen comprises a backlight module and a display panel which are arranged along a first direction; the display panel comprises a first substrate, a first electrode, a cholesteric liquid crystal, a second electrode and a second substrate which are arranged along a first direction, wherein the first electrode and the second electrode are used for driving the cholesteric liquid crystal to enable the cholesteric liquid crystal to be in a transmission state or a reflection state; when the cholesteric liquid crystal is in a transmission state, the backlight module is in an opening state, and light rays generated by the backlight module penetrate through the cholesteric liquid crystal. When the cholesteric liquid crystal is in a transmission state, the backlight module is in an opening state, the display screen can realize initiative, and when the cholesteric liquid crystal is in a reflection state, the display screen realizes passive display by virtue of ambient light and is used for displaying the handwritten content of a user.
Referring to fig. 1, the display panel includes a backlight module 10, a display panel 20 and a protective cover 30 sequentially disposed along a first direction X. When the display panel 20 is in a transmissive state, the light generated by the backlight module 10 forms an image after passing through the display panel 20, and when the display panel 20 is in a reflective state, the content handwritten by the user can be reflected by the ambient light. The protective cover plate is used for protecting the display panel 10 from being damaged by external force.
The display panel 20 includes a first polarizer 21, a first substrate 22, a first electrode 23, a cholesteric liquid crystal 24, a second electrode 25, a color filter layer 26, a second substrate 27, and a second filter layer 28, which are sequentially disposed along a first direction X.
The first polarizer 21 and the second polarizer 28 both include polarizing films, and the polarizing films are usually polymer stretched films, such as PVA films (polyvinyl alcohol films), which have the advantages of high transparency, high ductility, good film forming characteristics, and the like. Optionally, the first polarizer 21 and the second polarizer 28 may further include a TAC (triacetyl cellulose) film, a protection film, and the like, where the TAC film may support the lower polarizing film, so as to ensure that the lower polarizing film does not retract, and protect the PVA film from being damaged by water vapor and ultraviolet rays; the protective film may protect the first polarizer 21 and the second polarizer 28 from external force.
The first substrate 22 and the second substrate 27 are disposed in the cell, and may be made of a glass material or a thin film having high light transmittance, and are used to support the structures such as the first electrode 23, the second electrode 25, the cholesteric liquid crystal 24, and the like in the cell.
The first electrode 23 and the second electrode 25 are used to drive the cholesteric liquid crystal 24. In this embodiment, the first electrode 23 is an opaque electrode, and the second electrode 25 is a transparent electrode, such as ITO (indium tin oxide). When the voltage applied between the first electrode 23 and the second electrode 25 is different, the cholesteric liquid crystal 24 assumes different states. Referring to FIG. 2, the first is a planar texture state (p-state), which can be understood as a reflective state; the second is the focal conic texture state (fc-state), which can be understood as the transmissive state; the third is vertical texture (h-state) or field nematic phase; the fourth is a varying planar state (p-state). Of these states of cholesteric liquid crystals, only the p-state and the fc-state are stable in the absence of an external field. The h state exists only when there is an external field, and the p state is a plane-like state with a helical pitch, which occurs mainly during the transition of the liquid crystal molecules from the homeotropic state to the planar state.
Optionally, when the voltage applied between the first electrode 23 and the second electrode 25 is within a first threshold range, the cholesteric liquid crystal 24 is in a transmissive state, and at this time, the backlight module 10 is in an on state, the light generated by the backlight module 10 can pass through the cholesteric liquid crystal 24, and the display screen realizes active display through the backlight module 10, which is equivalent to a normal liquid crystal display screen; when the voltage applied between the first electrode 23 and the second electrode 25 is within the second threshold range, the cholesteric liquid crystal 24 is in a reflective state, the backlight module 10 is in a closed state, and at this time, a user can write handwriting on the display screen, and the cholesteric liquid crystal in a corresponding deformation region is changed to form handwriting due to deformation of the display panel caused by the pressure of the handwriting, so that the handwriting can be observed through reflection of ambient light. Therefore, the functions of the handwriting board and the liquid crystal display can be realized simultaneously, and in the handwriting mode, the display light of the display screen is the reflected light of the environment, so that the energy consumption is very low, and the eyes cannot be damaged.
In this embodiment, the first threshold range is 0 to 15V, and the second threshold range is 15 to 25V. Note that the driving voltage of the cholesteric liquid crystal in the present invention is higher than that of the general liquid crystal.
Of course, the reflective and transmissive states may also be obtained in other ways. For example, for cholesteric liquid crystal in h state, when the voltage drops rapidly to zero, the liquid crystal molecules return to p state; when the voltage is slowly decreased, the liquid crystal molecules are transformed into the fc state.
The color filter layer 26 includes a plurality of black matrixes 261 and color resists 262 (e.g., red resists, green resists, and blue resists) disposed between the black matrixes 261. When the cholesteric liquid crystal 24 is in a transmissive state, the black matrix 261 can cover the first electrode 23 to prevent the reflected light of the first electrode 23 from affecting the display light, and the color resistor 262 can precisely select the light wave of a small-range wavelength band to be passed through, and filter out other wavelength bands which are not desired to be passed through, so that the human eye can receive a saturated color light.
In this embodiment, the color filter layer 26 is located between the second electrode 25 and the second substrate 27; in other embodiments, the color filter layer 26 may also be located between the first electrode 23 and the cholesteric liquid crystal 24. In practice, the color filter layer 26 may be disposed between the first electrode 23 and the second substrate 27 to ensure that the black matrix 261 covers the first electrode 23.
Referring to fig. 3, in another embodiment, the display screen further includes a touch panel 40, and other structures are similar to those of the foregoing embodiments. The display panel 20, the touch panel 40 and the protective cover 30 are sequentially disposed along a first direction. Unlike the foregoing embodiments, in the present embodiment, handwriting is performed by the touch panel 40, and unlike the principle of a handwriting pad, the display panel of the present embodiment is not deformed during handwriting. When the user operates the touch panel 40, the voltage applied between the first electrode 23 and the second electrode 25 is controlled to make the cholesteric liquid crystal in a reflective state and present a touch trajectory of the user, which is similar to the principle of handwriting on a touch screen, except that the reflected light of the ambient light is used as the display light of the display screen.
Optionally, the touch panel 40 is connected to the display panel 20 through a full-lamination process, and the full-lamination process is adopted, so that the thickness of the display screen is reduced, and dust is prevented from entering the touch sensor.
Referring to fig. 4, in another embodiment, the display panel 20, the protective cover 30 and the touch panel 40 are sequentially disposed along a first direction X. The position of the touch panel 40 is selected more, and is not listed in this embodiment.
In another aspect, the present invention further provides a display device, which includes the display screen of any one of the foregoing embodiments. The display device is, for example, a mobile phone, a tablet computer, a monitor, a notebook computer, a flat tv, a conference tablet, and other devices having a display function. Of course, the display device may also include other components, such as a processing system, a power supply system, and the like. Further, the display device may further include a storage system, a communication system, and the like, and this embodiment is not described in detail.
In another aspect, the present invention further provides a display method for the display device. In this embodiment, the display method includes:
step S1: and receiving a control instruction of a user and selecting a display mode.
Optionally, the control instruction may be a remote control instruction sent by a remote control device, and the remote control device may be a dedicated remote controller or a terminal device integrating a remote control function; the control instruction can also be a key instruction and is sent out by operating an entity key on the display device; the control instructions may also be touch instructions. The display modes of the display device are, for example, a backlight display mode (corresponding to the cholesteric liquid crystal being in a transmissive state) and a reflective display mode (corresponding to the cholesteric liquid crystal being in a reflective state).
Step S2: and controlling the state of the cholesteric liquid crystal and the state of the backlight module according to the display mode selected by the user.
Alternatively, the control process may be performed by a processing element. When the display mode selected by the user is the backlight display mode, controlling the voltage applied between the first electrode 23 and the second electrode 25 to make the cholesteric liquid crystal 24 in the transmission state and simultaneously controlling the backlight module 10 to be turned on; when the display mode selected by the user is the reflective display mode, the voltage applied between the first electrode 23 and the second electrode 25 is controlled to make the cholesteric liquid crystal 24 in the reflective state, and the backlight module 10 is controlled to be turned off.
When the cholesteric liquid crystal is in a transmission state, the backlight module is in an open state, the display screen is used for active display, and when the cholesteric liquid crystal is in a reflection state, the display screen realizes passive display by virtue of ambient light and is used for displaying the handwritten content of a user.
Although the present invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
