Detailed Description
In order to make the technical problems solved by the present utility model, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the embodiments of the present utility model will be described in further detail below with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model.
As shown in fig. 1 and fig. 2, the touch display screen provided by the utility model comprises a display layer 1, a touch layer 2, a pattern film layer 3 and a light-transmitting cover plate 4. The display layer 1 is capable of receiving an electric signal, an image signal, and displaying an image. The display layer 1 has a light emitting surface on which light emitting elements are distributed. For example: when the touch display screen is an OLED screen, the Light emitting element is an Organic Light emitting diode (Organic Light-EmittingDiode, OLED); when the touch display screen is an LCD screen, the light emitting element is a thin film transistor (ThinFilmTransistor, TFT). The touch layer 2 has a capacitive touch circuit or a resistive touch circuit, and generates a corresponding electrical signal by a touch operation of a user. The pattern film layer 3 includes an optical base film 31 and a pattern layer 32, and the pattern layer 32 is formed on the optical base film 31 by means of ink printing, spraying or gravure. The pattern layer 32 is an ornamental pattern such as a motif, wood grain, solid background pattern, or colored background pattern. The transparent cover plate 4 has good light transmittance, and the transparent cover plate 4 is a glass plate.
Along the thickness direction of the touch display screen, the touch display screen is provided with a display surface and a back surface which are opposite to each other, and when a user uses the touch display screen or views the touch display screen, the display surface of the touch display screen faces the user. Along the thickness direction of touch-control display screen, display layer 1, touch-control layer 2, pattern rete 3 and printing opacity apron 4 arrange in proper order, and display layer 1 is located the one side that is close to the back of touch-control screen, and printing opacity apron 4 is located the one side that is close to the display surface of touch-control screen. The luminous surface of the display layer 1 faces the transparent cover plate 4, the touch control layer 2 is positioned between the luminous surface of the display layer 1 and the transparent cover plate 4, and the pattern film layer 3 is positioned between the touch control layer 2 and the transparent cover plate 4. When the light emitting surface of the display layer 1 is lighted and displays an image, light emitted on the light emitting surface sequentially passes through the touch layer 2, the pattern film layer 3, and the light-transmitting cover plate 4 and is transmitted outward, so that a user can view the image on the display layer 1. When the light emitting surface of the display layer 1 is not lighted, i.e., the display layer 1 is in a turned-off state, external natural light is irradiated to the pattern film layer 3 through the light-transmitting cover plate 4 and reflected to the outside, so that a user can view the pattern on the pattern film layer 3.
It can be understood that when the touch display screen is in the off state, the whole touch display screen can display a black picture. There is great colour difference between touch display screen and the colour of surrounding environment, influences holistic display effect. By arranging the pattern film layer 3 in the touch display screen, the touch display screen can display patterns on the pattern film layer 3 when the touch display screen is in a screen-off state. The touch display screen can still display patterns, wood grains or pure-color background patterns when the touch display screen is in a screen-off state, so that the color difference between the touch display screen and the surrounding environment is reduced, and the static visual effect of the touch display screen in the screen-off state is improved.
Optionally, the touch display screen further comprises a OCA (OpticallyClearAdhesive) optical adhesive layer 5.OCA optical cement is a special adhesive for cementing transparent optical elements in the prior art, and has the characteristics of no color, transparency, light transmittance of more than 95 percent and the like. The touch control layer 2 and the pattern film layer 3 are fixedly bonded through the OCA optical adhesive layer 5, and the pattern film layer 3 and the light-transmitting cover plate 4 are fixedly bonded through the OCA optical adhesive layer 5.
Optionally, the touch layer 2 includes two parallel transparent conductive layers 21 disposed at intervals, and an adhesive layer 22 is disposed between the two transparent conductive layers 21. The adhesive layer 22 is the same as the OCA optical adhesive layer 5 in material, and both transparent conductive layers 21 are adhered and fixed by the OCA optical adhesive. A plurality of touch circuits are respectively arranged on the two transparent conductive layers 21, and the touch circuits in the two transparent conductive layers 21 are mutually capacitively coupled so as to generate corresponding electric signals during touch operation. Of course, in another embodiment, the touch layer 2 may also include a transparent conductive layer 21, and the touch circuits that are capacitively coupled to each other are disposed on the transparent conductive layer 21.
It is understood that the touch layer 2 includes Indium Tin Oxide (ITO), nano silver wire, and the like. In practical applications, the transparent conductive layer 21 may be made of indium tin oxide, and the touch circuit may be made of nano silver wire. The transparent cover plate 4 is usually made of glass, which is a hydrophilic material, and a water washing process is performed during the processing of the transparent cover plate 4, so that a part of water vapor is attached to the transparent cover plate 4. Through set up pattern rete 3 between touch-control layer 2 and printing opacity apron 4 for pattern rete 3 separates touch-control layer 2 and transparent apron 4, avoids the steam on the printing opacity apron 4 to pass OCA optical glue layer 5 and enter into touch-control layer 2 and produce chemical reaction with the silver ion and lead to the working property of touch-control layer 2 to reduce. Meanwhile, the transparent cover plate 4 is made of soda lime glass, and the pattern film layer 3 can avoid the defects of whitening, cracking and the like of the touch layer 2 caused by the fact that sodium ions in the transparent cover plate 4 migrate to the touch layer 2.
Alternatively, the pattern film layer 3 includes an optical base film 31 and a pattern layer 32. The optical base film 31 is a PET (polyethylene terephthalate) film. The transmittance of the optical base film 31 is more than 90%. The pattern layer 32 is a paint formed by using polyester resin or polyester ethylene (PVC) as a base material and adding nano-scale color master and various additives. The pattern layer 32 is formed on the optical base film 31 by an ink printing, spraying or gravure process so that the entire pattern film layer 3 exhibits a corresponding pattern, for example: wood grain, decorative pattern, etc. Since the pattern layer 32 is provided on the optical base film 31, the transmittance of the entire film layer 3 is reduced.
The overall transmittance of the patterned film layer 3 is 30% -70%. It can be understood that the transmittance of the patterned film layer 3 may affect the display effect of the entire touch display screen. The transmittance of the patterned film layer 3 includes, but is not limited to, 30%, 40%, 50%, 60%, and 70%. When the transmittance of the pattern film layer 3 is selected to be 30%, the transmittance of the light emitted by the display layer 1 on the pattern film layer 3 is lower when the touch display screen is in a bright screen state, so that the image picture presented on the display surface of the touch display screen is dark. When the touch display screen is in a screen-off state, the display layer 1 does not emit light. The external light irradiates the pattern film layer 3, and the transmittance of the light is low, so that most of the light is reflected to the outside, and further the pattern picture corresponding to the pattern layer 32 presented on the display surface of the touch display screen is bright (clear); when the transmittance of the pattern film layer 3 is selected to be 70%, the transmittance of the light emitted by the display layer 1 on the pattern film layer 3 is higher when the touch display screen is in a bright screen state, so that the image picture presented on the display surface of the touch display screen is brighter. When the touch display screen is in a screen-off state, the display layer 1 does not emit light. The external light irradiates onto the pattern film layer 3, and the transmittance of the light is high, so that a small portion of the light is reflected to the outside, and the pattern image corresponding to the pattern layer 32 displayed on the display surface of the touch display screen is dark (dim). Therefore, in practical application, the transmittance of the pattern film layer 3 can be reasonably selected according to the specific use situation of the touch display screen.
The thickness of the pattern layer 32 is 30nm to 200 μm. The thickness of the pattern layer 32 directly affects the transmittance of the entire pattern film layer 3. That is, the thinner the pattern layer 32, the higher the overall transmittance; the thicker the pattern layer 32, the lower the overall transmittance. Therefore, in practical application, the thickness of the pattern layer 32 can be reasonably selected according to the specific use situation of the touch display screen, so as to ensure that the transmittance of the pattern film layer 3 is between 30% and 70%. Specifically, the thickness of the pattern layer 32 includes, but is not limited to, 30nm, 100nm, 500nm, 1000nm, 50 μm, 100 μm, 150 μm, and 200 μm.
Alternatively, the optical base film 31 has a first side facing the transparent cover plate 4 and a second side facing the touch layer 2, and the pattern layer 32 is disposed on the first side, or disposed on the second side, or disposed on both the first side and the second side. In practical applications, the setting position of the pattern layer 32 can be flexibly selected according to the actual setting thickness of the pattern layer 32 and the pattern forming process.
Alternatively, referring to fig. 2, a pattern layer 32 is disposed on the first side of the optical base film 31, and the pattern layer 32 covers the entire first side. The structure is suitable for forming a solid background pattern. Referring to fig. 3, a pattern layer 32 is disposed on the first side of the optical base film 31, and the pattern layer 32 does not entirely cover the first side. The pattern layer 32 has a hollowed-out portion therein so that the entire pattern layer 32 forms a unique shape. The structure is suitable for forming patterns such as wood grains, decorative patterns and the like.
Optionally, a gap 6 is provided between the display layer 1 and the touch layer 2. The display layer 1 is separated from the touch layer 2, so that the problem of touch interference caused by direct contact between the display layer 1 and the touch layer 2 can be avoided. The touch display screen with the structure is manufactured by adopting a frame pasting technology, namely, the display layer 1 and the touch layer 2 are fixed through double faced adhesive tape, and the double faced adhesive tape is positioned at the edge positions of the display layer 1 and the touch layer 2. This structure separates the display layer 1 from the touch layer 2 and forms an air layer.
Optionally, the gap 6 between the display layer 1 and the touch layer 2 is filled with a transparent medium. The transparent medium may be made of PC (polycarbonate), PET or PMMA (polymethyl methacrylate) material. The touch display screen with the structure is manufactured by adopting a zero attaching process, namely, the display layer 1 and the touch layer 2 are fixed through double-sided adhesive, the double-sided adhesive is positioned at the edge positions of the display layer 1 and the touch layer 2, and a transparent medium is filled in a gap between the display layer 1 and the touch layer 2.
Optionally, a glue layer is arranged between the display layer 1 and the touch layer 2. The adhesive layer can be a water adhesive or an OCA optical adhesive. The touch display screen with the structure is manufactured by adopting a full-lamination process, namely the display layer 1 and the touch layer 2 are bonded together through an adhesive layer.
Optionally, the touch display screen further includes a frame structure, and the display layer 1, the touch layer 2, the pattern film layer 3, and the periphery of the light-transmitting cover plate 4 are encapsulated on the frame structure. The frame structure is also provided with various electronic devices, which play roles of electric energy transmission, signal processing, circuit control and the like.
The transmittance described in this embodiment is the transmittance of light in the medium.
The touch display screen in the embodiment can be applied to mobile phones, flat plates, conference display equipment, exhibition hall display equipment, curtain screens and the like. The pattern display effect of the pattern film layer 3 can be flexibly selected according to the application scene which is not used. For example, when the touch display screen is hung on a wall surface for use, the pattern layer 32 in the pattern film layer 3 can be set to be a pure-color pattern matched with the color of the wall surface, so that the color difference between the touch display screen and the wall surface in the screen-off state is reduced, and the overall display effect is improved. When the touch display screen is used in an exhibition hall, the pattern layer 32 in the pattern film layer 3 can be set to be a pattern such as wood grain, a decorative pattern and the like, so that the static visual effect of the touch display screen in the screen-off state is improved.
