Detailed Description
In order to facilitate understanding of the present invention, the touch display device, the touch display panel and the polarizer thereof will be described more fully with reference to the accompanying drawings. The preferred embodiments of the touch display device, the touch display panel and the polarizer thereof are shown in the attached drawings. However, the touch display device and the touch display panel and polarizer thereof may be implemented in many different forms and are not limited to the embodiments described herein. On the contrary, the embodiments are provided to make the disclosure of the touch display device and the touch display panel and polarizer thereof more thorough.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terms used in the description of the touch display device and the touch display panel and polarizer thereof are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 and fig. 2, a touch display panel 10 is provided in the present embodiment, and the touch display panel 10 can be applied to a mobile phone, a notebook computer, a game machine, and the like. Specifically, the touch display panel 10 includes a protective cover 100, a polarizer 200, a touch module 300, and a display module 400. Wherein, the material of the protective cover plate 100 is glass. In other embodiments, the material of the protective cover 100 may also be transparent plastic, acrylic, or any other material with a certain light transmittance that can protect the structure to which it is attached.
The polarizer 200 and the protective cover 100 are stacked, and the main function is to filter out parasitic light, to filter 99% glare, to enhance visual acuity, to improve color contrast and maximum visual comfort, i.e. the blind light is absorbed by the polarizer, and only the effective light in the same direction enters the sight line, so that the eyes can see objects clearly. Specifically, the polarizer 200 includes a polarizing body 210 and a decoration layer 220, the decoration layer 220 is disposed on the surface of the polarizing body 210 close to the protective cover 100, that is, the decoration layer 220 is located between the protective cover 100 and the polarizing body 210, and the decoration layer 220 divides the polarizing body 210 into a polarizing region 210a and a decoration region 210b, that is, the decoration layer 220 covers the decoration region 210 b.
Due to the low light transmittance of the decoration layer 220, a part of the structure of the protective cover 100 can be shielded, so that the touch display panel 10 can be divided into the visible region 12 and the non-visible region 14. It is understood that the decoration layer 220 can be formed on the polarization body 210 by printing, spraying or sputtering.
The decorative layer 220 is disposed on the polarizer 200, so that the PET film is not additionally disposed on the touch display panel 10 to form the decorative layer 220, and the thickness of 0.075mm to 0.1mm can be saved at least. Therefore, not only the material cost is reduced, but also the thickness of the entire touch display panel 10 is reduced, thereby increasing the electrical induction characteristic and improving the quality of the touch display panel 10.
The touch module 300 is disposed on the surface of the polarizer 200 away from the protective cover 100, and includes a touch lead (not shown) located in the non-visible area 14, and the touch lead is covered by the decoration layer 220 to avoid affecting the display effect of the touch display panel 10. In this embodiment, the touch lead is made of a metal material with conductive properties by a yellow light process of exposure, development and etching.
The display module 400 is disposed on the surface of the touch module 300 away from the polarizer 200, and the display module 300 can provide a light source for the touch display panel 10 to facilitate displaying.
Above-mentioned touch-control display panel 10 directly sets up decorative layer 220 on polarisation body 210, avoids additionally increasing the diaphragm that the one deck was provided with the decorative layer, not only can reduce touch-control display panel 10's whole thickness, and then reduces touch-control display device's thickness, can also save the processing procedure of laminating decorative diaphragm, simplifies the manufacture craft.
It should be noted that the polarizer 200 is a multi-layer composite material, which is not prone to generate color red stripes, and in addition, the problem of color red stripes is not prone to be generated in visual effect due to optical polarization compensation. Further, the thickness of the polarizer 200 is about 0.1mm, and can be reduced to 0.1mm or less, and the functions are complete. If the polarizer 200 is bent, the stress of the bent part is small, the laminating quality is good, and the polarizer can be used for laminating curved surfaces. The polarizer 200 has such characteristics that when the polarizer is applied to a curved (3D) touch display device, the thickness of the 3D touch display device can be reduced to increase the electric induction characteristic, and the rainbow texture problem can be prevented.
Further, the protective cover 100 includes a main body 110 and a bending portion 120 connected to the main body 110, and the bending portion 120 is located in the non-visible region 14. Accordingly, the polarization region 210a and the decoration region 210b are connected in a bending manner and respectively correspond to the main body 110 and the bending portion 120. Thus, the touch display panel 10 can achieve a three-dimensional effect to achieve a good visual effect. Meanwhile, in the embodiment, because the PET film is omitted from the touch display panel 10, the rainbow effect is not generated when the touch display panel 10 is manufactured into a three-dimensional panel, and the display quality can be ensured.
Specifically, a first arc portion 130 is disposed between the main body portion 110 and the bending portion 120, a second arc portion 212 is disposed between the polarization region 210a and the decoration region 210b, the second arc portion 212 is disposed opposite to the first arc portion 130, the first arc portion 130 includes a first side surface 132 (shown by a dotted line in fig. 1), and the first side surface 132 is connected to the main body portion 110, that is, the first side surface 132 is an interface between the first arc portion 130 and the main body portion 110. The second arc-shaped portion 212 includes a second side 212a (shown by a dashed line in fig. 1), and the second side 212a is connected to the polarization region 210b, i.e., the second side 212a is an interface between the second arc-shaped portion 212 and the polarization region 210b, and is also shown by a dashed line in the figure. In other embodiments, the first arc-shaped portion 130 and the second arc-shaped portion 212 may be omitted, in which case the main body portion 110 and the bending portion 120 are vertically connected, and the polarization region 210a and the decoration region 210b are also vertically connected.
Further, the decoration layer 220 includes a first ink layer 222 and a second ink layer 224, the second ink layer 224 is disposed on the surface of the polarization body 210, and the first ink layer 222 is disposed on the surface of the second ink layer 224 away from the polarization body 210. The first ink layer 222 includes a first inner side 222a and a first outer side (not shown), which are opposite to each other, the first inner side 222a is coplanar with the second side 212a, and the first outer side is coplanar with the side of the polarization region 210b away from the second arc-shaped portion 212. The second ink layer 224 includes a second inner side 224a and a second outer side (not shown), which are oppositely disposed, the second inner side 224a is located between the first inner side 222a and the first outer side, and the second outer side is coplanar with the first outer side, i.e., the width of the second ink layer 224 is smaller than the width of the first ink layer 222, so that the decoration layer 220 is stepped, and the first inner side 222a is connected with the second inner side 224a to form a stepped surface. Thus, the decoration layer 220 is set as two ink layers to prevent light leakage.
Generally, the first ink layer 222 defines the maximum range of the non-visible area 14, and the second ink layer 224 is used to increase the light shielding performance, so as to prevent the originally set non-visible area 14 from further increasing due to the printing tolerance, so that the decoration layer 220 is configured to be stepped. In other embodiments, the first inner side surface 222a may also be disposed between the second side surface 212a and the side surface of the decoration region 210b far from the second arc-shaped portion 212, at this time, the second side surface 212a is no longer an interface between the second arc-shaped portion 212 and the polarization region 210b, and the polarization region 210a may extend to a position corresponding to the first inner side surface 222 a. In this way, the range of the visible region 12 of the touch display panel 10 can be further increased.
It can be understood that decorative layer 220 can be three or even four ink layers, further increasing the light-shielding performance, and at this time, decorative layer 220 is still configured in a step shape.
Further, the touch display panel 100 further includes a first connection layer 500, and the first connection layer 500 is disposed on the surface of the protective cover 100 close to the polarization body 210 and is used for connecting the protective cover 100 and the polarization body 210. In this embodiment, the first connection layer 500 is an Optical Clear Adhesive (OCA) layer, and has good light transmittance.
In the non-visible region 14, the polarized body 210 is provided with the decoration layer 220, so that a gap exists between the protective cover 100 and the polarized body 210 in the visible region 12. Therefore, the touch display panel 100 further includes a transparent insulating layer 600, and the transparent insulating layer 600 is disposed on the surface of the polarization body 210 close to the protective cover 100 and extends to the decoration layer 220. In other embodiments, the transparent insulating layer 600 may also be an air layer or an OCA layer.
In this embodiment, the touch display panel 10 is a display touch display panel made of Organic Light Emitting Diodes (OLEDs), and therefore, the display module 400 in the touch display panel 10 is an active matrix organic light emitting diode panel module, which is disposed on the surface of the touch module 300 away from the polarizer 210 and can provide a light source for the touch display panel 10. The OLED has advantages of self-luminescence, wide viewing angle, almost infinite contrast, low power consumption, extremely high response speed, and the like, and can realize the thinning of the touch display panel 10. It can be understood that the touch module 300 and the active matrix organic light emitting diode panel module are connected 700 through the second connection layer. The touch module 300 is disposed on the surface of the polarizer 200 away from the protective cover 100, and the active matrix organic light emitting diode module is disposed on the surface of the touch module 300 away from the polarizer 200. Like the first connection layer 500, the second connection layer 700 is also made of OCA.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express a few embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
