Background
Along with the increasing requirements of the market and users on the intellectualization, automation, convenience and safety of automobiles, software of various functions required to be realized by the vehicle-mounted touch screen is more and more abundant. In the prior art, a vehicle-mounted touch screen can only display a specific number of application programs on a touch interface for a user to operate or view, and the requirement of the user on more application programs cannot be met. The user needs to manually switch the touch interfaces to display different applications, and different touch interfaces can only display one color, and patterns with different colors cannot be displayed on the same touch interface.
SUMMERY OF THE UTILITY MODEL
The application provides a display device. The display device can display patterns with different colors on the same touch interface, so that the display device can be switched among a plurality of display interfaces, and the display device is intelligent and convenient. The application also provides a terminal device.
In a first aspect, a display device is provided. The display device can be applied to terminal equipment. The display device comprises a luminous layer and a photosensitive layer which is arranged on the light-emitting side of the luminous layer in a laminated mode. The photosensitive layer is arranged on the light-emitting side of the light-emitting layer in a laminated manner, so that light with different wavelengths emitted by the light-emitting layer can be irradiated to the photosensitive layer.
The photosensitive layer comprises M photosensitive sublayers, and M is an integer greater than or equal to 2. That is, the photosensitive layer includes two or more photosensitive sublayers. The M layers of the photosensitive sublayers are sequentially stacked in the light emitting direction of the light emitting layer. That is, two or more photosensitive sublayers sequentially stacked are provided in the light exit direction of the light emitting layer. The light emitting layer is used to switch light emission among the M wavelengths. Each photosensitive sublayer in the photosensitive layer corresponds to M kinds of wavelength light respectively and is used for being excited by the corresponding wavelength light to display patterns with different colors.
each photosensitive sublayer in the photosensitive layer displays patterns with different colors under the excitation of light with different wavelengths. That is, each photosensitive sublayer in the photosensitive layer is used to display a pattern of a different color. Since M is an integer greater than or equal to 2, the photosensitive layer can display a pattern of two or more colors. That is, the display device is capable of displaying a pattern of two or more colors.
In this embodiment, when light of different wavelengths emitted by the light emitting layer is irradiated onto the photosensitive layer, different photosensitive sublayers in the photosensitive layer can be activated to display patterns of different colors, so that the display device displays the patterns of different colors. Because the light-emitting layer can emit light in M wavelengths in a switching mode, the display device can change the display interface to display patterns with different colors without manually switching the touch interface. That is, the display device can display patterns with different colors on the same touch interface, so that the display device can be switched among a plurality of display interfaces, and the display device is more intelligent and convenient.
In one embodiment, the light emitting layer of the display device automatically switches light emission in M wavelengths, which allows the display device to automatically switch between multiple display interfaces, thereby making the display device more automated. Each display interface in the plurality of display interfaces displays different colors or different patterns.
Specifically, the display device includes a controller. The controller controls the light emitting layer to switch light emission among the M wavelengths according to a preset frequency.
In this embodiment, the controller controls the light emitting layer to emit light with different wavelengths according to a preset frequency, so that the display device can realize automatic switching among a plurality of display interfaces, and the display device is more automatic, intelligent and convenient. Wherein, the controller can control the luminous layer to automatically switch the luminous frequency to be the same or different. That is, the switching intervals of the light emitted from the light emitting layers can be the same or different.
In one embodiment, the controller can control the light emitting layers to automatically switch display colors at the same or different frequencies. That is, the switching intervals of the emission wavelengths of the light emitting layers can be the same or different. The intervals of the light emitted by the light emitting layers are the same, so that the frequency of the light emitting layers for switching the light emitting wavelength is kept consistent, and a user can predict the time for the display device to display the next display interface. The intervals at which the light emitting layers emit light can also be different. For example: when some common software icons exist in the display interface, the display time of the display interface can be longer, so that the frequency of seeing the common software by a user is higher.
When the colors displayed by one of the display interfaces are multiple, if one of the colors displayed by the display interface is different from the colors displayed by other display interfaces, the display interface is judged to be different from the colors displayed by other display interfaces. That is, each of the plurality of display interfaces displays a different color, and each color displayed by the display interface is not required to be different, but only at least one color displayed by the display interface is required to be different. Accordingly, each of the plurality of display interfaces displays different patterns, and each display interface is not required to display different patterns, but only needs to display different patterns.
In one embodiment, the photoactive sub-layer includes a photoactive pigment that reacts under illumination with light of a particular wavelength. The photosensitive pigment can enable the photosensitive sub-layer to display a pattern of a specific color.
Wherein the photosensitive pigment includes sub-photosensitive pigments that are photosensitive to different colors. When M is equal to 3, that is, the photosensitive layer includes three photosensitive sublayers. At this time, the photosensitive pigment includes at least three kinds of sub-photosensitive pigments.
In the embodiment of the present application, each sub-photosensitive pigment is activated only by the light with a specific wavelength, so that the corresponding color is displayed. If the sub-photosensitive pigment is not irradiated with light of a corresponding wavelength, the sub-photosensitive pigment is not activated, and thus the sub-photosensitive pigment does not exhibit a color. For example: the photosensitive pigment in the photosensitive layer comprises blue sub-photosensitive pigment sensitive to blue and red sub-photosensitive pigment sensitive to red, and when the wavelength of light emitted by the light-emitting layer is blue wavelength light, only the blue sub-photosensitive pigment is activated, so that blue is displayed. And the red sub-photosensitive pigment does not show red color because it is not activated.
In one embodiment, the light emitting layer is configured to emit light of M wavelengths and is invisible light. The photosensitive layer comprises M photosensitive sublayers, and the M photosensitive sublayers of the photosensitive layer are used for being excited by the light with the M wavelengths emitted by the luminous layer in a one-to-one correspondence manner to display M color patterns.

And the three photosensitive sublayers of the photosensitive layer are used for being excited by the light with the three wavelengths in a one-to-one correspondence manner to display patterns with three colors. That is, each of the three photosensitive sublayers displays a color pattern, and the colors displayed by each photosensitive sublayer are different.
Specifically, three photosensitive sublayers in the photosensitive layer include one photosensitive sublayer capable of being activated by light of a red wavelength emitted by the light emitting layer, one photosensitive sublayer capable of being activated by light of a green wavelength emitted by the light emitting layer, and one photosensitive sublayer capable of being activated by light of a blue wavelength emitted by the light emitting layer. In the embodiment of the present application, the order of the light with three wavelengths of red, green and blue emitted from the light emitting layer is not limited, and the time interval between displaying colors is also not limited. Accordingly, the stacking order of the three photosensitive sublayers in the photosensitive layer is also limited. In an alternative embodiment, the color sequence emitted by the light emitting layer can be red, green and blue wavelengths, and the stacking sequence of the three photosensitive sublayers in the photosensitive layer can be a photosensitive sublayer activated by red wavelength light, a photosensitive sublayer activated by green wavelength light and a photosensitive sublayer activated by blue wavelength light.

The photosensitive layer comprises more than three photosensitive sublayers. Specifically, the number of photosensitive sublayers in the photosensitive layer is adapted to the type of light emitted by the light emitting layer. For example, the light emitting layer can emit light of four wavelengths, and the photosensitive layer includes four photosensitive sublayers; the luminous layer can emit light with five wavelengths, and the photosensitive layer comprises five photosensitive sublayers.
In this implementation, the light emitting layer emits light with three or more wavelengths, and the photosensitive layer includes three or more photosensitive sublayers, so that the display device can be switched among three or more display interfaces, and the number of display interface switching is increased, so that the display device can display icons of more kinds of functional software.

When the light emitting layer 41 emits light of a certain wavelength band, the light of the wavelength band irradiates the photosensitive layer 42, and one photosensitive sublayer 421 in the photosensitive layer 42 displays a pattern of a corresponding color. For example, when the luminescent layer 41 emits infrared light of a certain wavelength band, the infrared light of the wavelength band is irradiated to the photosensitive layer 42, and one photosensitive sublayer 421 in the photosensitive layer 42 displays a pattern of a corresponding color; when the luminescent layer 41 emits infrared light of another wavelength band, the infrared light of the wavelength band irradiates the photosensitive layer 42, and one photosensitive sublayer 421 in the photosensitive layer 42 displays a pattern of another corresponding color; similarly, the ultraviolet light of different bands is similar.
Since M is an integer of 2 or more, the photosensitive layer 42 can display a pattern of two or more colors. That is, the display device 2 can display a pattern of two or more colors.
In this embodiment, when light with different wavelengths emitted from the light emitting layer 41 is irradiated onto the photosensitive layer 42, different photosensitive sub-layers 421 in the photosensitive layer 42 can be activated to display different color patterns, so that the display device 2 displays different color patterns. Since the light emitting layer 41 can switch light emission among M wavelengths, the display device 2 can change the display interface to display different color patterns without manually switching the touch interface. That is, the display device 2 can display patterns with different colors on the same touch interface, so that the display device 2 is switched among a plurality of display interfaces, and the display device 2 is more intelligent and convenient.
further, the controller 3 is configured to control the light emitting layer 41 to switch the light emitting wavelength, so that the display device 2 excites different photosensitive sub-layers 421 to display different color patterns. When the display device 2 switches light emission between the plurality of photosensitive sub-layers 421, the display device 2 can switch between a plurality of display interfaces. Wherein, each display interface in the plurality of display interfaces displays different colors or different patterns.
In one embodiment, the controller 3 is configured to control the light emitting layer 41 to switch light emission among M wavelengths according to a predetermined frequency. The frequency at which the controller 3 controls the light-emitting layer 41 to automatically switch the emission wavelength can be the same or different. That is, the switching intervals of the emission wavelengths of the light emitting layers 41 may be the same or different. The intervals of the light emitting wavelengths of the light emitting layers 41 are the same, so that the frequency of switching the light emitting wavelengths of the light emitting layers 41 is kept consistent, and thus, a user can predict the time when the display device 2 displays the next display interface. The intervals of the light emission wavelengths of the light emitting layers 41 may be different. For example: when some common software icons exist in the display interface, the display time of the display interface can be longer, so that the frequency of seeing the common software by a user is higher.
When the display colors of one display interface in the plurality of display interfaces are multiple, if the display colors of one display interface are different from those of other display interfaces, the display colors of the display interface are judged to be different from those of other display interfaces. That is, each of the plurality of display interfaces displays a different color, and not each of the display interfaces displays a different color, but only at least one of the display interfaces displays a different color. Accordingly, each of the plurality of display interfaces displays different patterns, and each of the plurality of display interfaces is not required to display different patterns, but only at least one of the patterns that the display interfaces are required to display is different.
As shown in fig. 4, when the display device 2 displays one color, the display interface displays one pattern; when the display device 2 displays another color, the display interface displays another pattern. The two display interfaces have different colors and patterns. Here, the display interface of the display device 2 displays a plurality of patterns, and if one of the patterns changes, it is determined as a different display interface.
As shown in fig. 5, when the display device 2 displays one color, the display interface displays one pattern; when the display device 2 displays another color, the display interface displays another pattern. The two display interfaces have different colors and patterns. Here, one pattern is displayed on the display interface of the display device 2, and if the pattern changes, it is determined as a different display interface.
In the present embodiment, the light with different wavelengths emitted by the light emitting layer 41 is irradiated to the photosensitive layer 42, so that different photosensitive sub-layers 421 in the photosensitive layer 42 are excited to display different color patterns, and the display device 2 can display different colors. Because the light with different wavelengths displayed by the light emitting layer 41 is controlled by the controller 3, the patterns with different colors can be automatically switched and displayed, so that the display device 2 is automatically switched among a plurality of display interfaces, and the display device 2 is more automatic, intelligent and convenient.
Further, the photosensitive sublayer 421 includes a photosensitive pigment that reacts under irradiation of light of a specific wavelength. The photosensitive pigment enables the photosensitive sublayer 421 to display a pattern of a specific color. Wherein the photosensitive pigment includes sub-photosensitive pigments that are photosensitive to different wavelengths. When M is equal to 3, that is, the photosensitive layer 42 includes three photosensitive sublayers 421. At this time, the photosensitive pigment includes at least three seed photosensitive pigments.
In the embodiment of the application, each sub-photosensitive pigment is activated only under the irradiation of light with a specific wavelength, so that the corresponding color can be displayed. If the sub-photosensitive pigment is not irradiated with light of a corresponding wavelength, the sub-photosensitive pigment is not activated, and thus the sub-photosensitive pigment does not display a color. For example: the photosensitive pigment in the photosensitive layer 42 includes a blue sub-photosensitive pigment sensitive to blue and a red sub-photosensitive pigment sensitive to red, and when the color displayed by the luminescent layer 41 is blue, only the blue sub-photosensitive pigment is activated, so that blue is displayed. And the red sub-photosensitive pigment does not show red color because it is not activated.
Further, the light emitting layer 41 is for emitting light of M wavelengths and is invisible light. Correspondingly, the photosensitive layer 42 includes M photosensitive sublayers 421, and the M photosensitive sublayers 421 of the photosensitive layer 42 are configured to be excited by the M wavelengths of light emitted by the light emitting layer 41 in a one-to-one correspondence to display M color patterns.
In the first embodiment of the present application, the light emitting layer 41 emits light with multiple invisible wavelengths, so that the display interface can be switched between multiple different interfaces, and the interference of the light emitting layer 41 emitting visible light with naked eyes on the display interface can be avoided, thereby improving the quality of the display device 2.
Further, the light emitting layer 41 is for emitting light of both infrared and ultraviolet wavelengths. The photosensitive layer 42 includes two photosensitive sublayers 421. The two photosensitive sublayers 421 are an infrared excitation pigment layer and an ultraviolet excitation pigment layer, respectively. Wherein, the infrared excitation pigment and the ultraviolet excitation pigment are both the prior art and can be selected correspondingly according to the requirement.
As shown in fig. 3, in one embodiment, the upper photosensitive sublayer 421 of the two photosensitive sublayers 421 is an infrared excitation pigment layer, and the lower photosensitive sublayer 421 is an ultraviolet excitation pigment layer. In another embodiment, the upper photosensitive sublayer 421 of the two photosensitive sublayers 421 is an ultraviolet excited pigment layer, and the lower photosensitive sublayer 421 is an infrared excited pigment layer. That is, in the embodiment of the present application, the alignment order of the photosensitive pigment layers is not limited.
When the luminescent layer 41 emits infrared light of a certain wavelength band, the infrared light of the wavelength band irradiates the photosensitive layer 42, and one photosensitive sublayer 421 in the photosensitive layer 42 displays a pattern of a corresponding color; when the light emitting layer 41 emits ultraviolet light, the ultraviolet light is irradiated to the photosensitive layer 42, and one photosensitive sublayer 421 in the photosensitive layer 42 displays a pattern of another corresponding color.
In the first embodiment of the present application, the light emitting layer 41 emits two kinds of infrared light and ultraviolet light with invisible wavelengths to the naked eye, so that the display interface can be switched between two different interfaces, and the interference of the visible light emitted by the light emitting layer 41 on the display interface can be avoided, thereby improving the quality of the display device 2.
In other embodiments, the light emitting layer 41 can also emit a plurality of infrared light with different wavelength bands or a plurality of ultraviolet light with different wavelength bands, and the photosensitive layer 42 includes three or more photosensitive sub-layers 421. Three or more photosensitive sub-layers 421 in the photosensitive layer 42 can emit different display colors corresponding to infrared light of different bands or ultraviolet light of different bands.
In the embodiment of the present application, the light emitting layer 41 emits infrared light or ultraviolet light with various wavelengths invisible to the naked eye, so that the display interface can be switched between various different interfaces, and the light emitting layer 41 can be prevented from emitting visible light to the naked eye to interfere with the display interface, thereby improving the quality of the display device 2.
further, the photosensitive sub-layer 421 is a photosensitive pigment layer having a predetermined pattern.
In this embodiment, the photosensitive sub-layer 421 is a photosensitive pigment layer with a predetermined pattern, that is, in this embodiment, the different patterns displayed on the display interface are directly determined by each photosensitive sub-layer 421 in the photosensitive layer 42, which reduces the requirement of the display device 2 on the processor or the controller 3. Wherein the different patterns can be printed by photosensitive ink.

In the process of fabricating the cover plate 43, the cover plate 43 includes a first protection film 432 and a second protection film 433. When the cover plate 43 is assembled to the touch layer 44, the second protective film 433 is removed and then adhered to the touch layer 44 by the first adhesive 45.
The first protection film 432 can protect the cover plate 43 and prevent the cover plate 43 from being scratched. When the cover plate 43 is not assembled with the touch layer 44, the second protective film 433 can protect the photosensitive layer 42 in the cover plate 43, so as to prevent the photosensitive layer 42 from being damaged.

The light emitting layer 41 is provided with a plurality of display regions. The light emitting layers 41 of different display areas are used to emit light of different wavelengths. The controller 3 is used to control the display areas so that the light emitting layers 41 in different display areas emit light of different wavelengths. Wherein the wavelengths of the different light emitted by each display region can be the same or different.
In this embodiment, different regions of the light emitting layer 41 are used for emitting light with different wavelengths, so that the display interface of the display device 2 can simultaneously display patterns of two colors, thereby realizing the partition display of the display interface. One part of the display device 2 displays a pattern of one color and the other part is capable of displaying a pattern of another color. The different areas display different color patterns, so that the display interface of the display device 2 can realize that the color and the pattern displayed in one part of the areas are kept unchanged, and the color and the pattern displayed in the other part of the areas can be changed. The pattern displayed in the area where the display interface of the display device 2 is kept unchanged can be a common software pattern, and the pattern displayed in the area where the display interface is changed can be an uncommon software pattern, so that different requirements of a user can be met, and the user experience of the display device 2 is improved.

The photosensitive layer 42 includes three photosensitive sublayers 421, and the three photosensitive sublayers 421 of the photosensitive layer 42 are used to be excited by the light with three wavelengths in a one-to-one correspondence manner to display the three color patterns. That is, each photosensitive sublayer 421 of the three photosensitive sublayers 421 displays a pattern of one color, and the color displayed by each photosensitive sublayer 421 is different.
In other embodiments, the light-emitting layer 41 can emit light at only two wavelengths that are visible to the naked eye, and the light-emitting layer 41 can also emit light at three or more wavelengths that are not visible to the naked eye.
