The inventors of the present application consider that the display panel 100 in the touch display panel 200 may adopt a display structure such as an LED, a Micro-LED, or an OLED. Therefore, the present application provides one possible implementation manner for the touch display panel 200 as follows:
as shown in fig. 8, the touch display panel 200 of the embodiment of the present application includes: a touch panel 210, and the display panel 100 adopting the LED or Micro-LED or OLED display structure provided in the foregoing embodiments.
The touch panel 210 is located between the cathode layer 170 and the first polarizer 110 in the display panel 100.
In this embodiment, the touch panel 210 is located between the cathode layer 170 and the first polarizer 110 in the display panel 100, that is, the touch panel 210 is located inside the display panel 100 adopting an LED or Micro-LED or OLED display structure, and since the pencil hardness of the first polarizer 110 is not less than 3H and not more than 9H, the first polarizer 110 can not only protect the display devices such as the cathode layer 170, the light emitting layer 160, and the anode layer 150, but also protect the touch panel 210.

Based on the same inventive concept, an embodiment of the present application provides a display device, including: the display panel 100 according to any of the previous embodiments. Alternatively, any of the touch display panels 200 provided in the foregoing embodiments.
The display device may be at least one of any products (or components) with a display function (or touch display function), such as an electronic whiteboard, a television, a digital photo frame, a mobile phone, an intelligent watch, a tablet computer, and the like.
In this embodiment, as the display device adopts any one of the display panels 100 provided in the foregoing embodiments or any one of the touch panels provided in the foregoing embodiments, the principle and technical effects thereof please refer to the foregoing embodiments, which are not described herein again.
The following description will be made for a display panel with an LCD display structure, by taking a specific case of a backlight structure with direct-type incident light and a specific case of a backlight structure with side-type incident light as examples.
Case one: the LCD display panel adopting the direct-type light-incident backlight source structure utilizes the glass diffusion plate to replace the traditional diffusion plate made of PS (polystyrene) or PC (polycarbonate). Glass density 2.4g/cm3(grams per cubic centimeter) and an elastic modulus > 68G Pa (gigapascal); the PS density is 1.04-1.9 g/cm3The elastic modulus is 3-3.5G Pa; the density of PC is 1.18-1.22 g/cm3The modulus of elasticity is 2.32G Pa. From the comparison of material properties, the glass has a higher density and thus a higher weight than conventional PS or PC diffuser plates.
Effect on weight loss: weight of cover plate (length x width x thickness x 2.4 g/cm)3) + PC or PS (length X width X thickness X1.9 g/cm)3Or 1.22g/cm3) Diffuser weight-glass diffuser weight (Length × Width × thickness × 2.4 g/cm)3). Taking 65inch as an example, assuming a cover plate thickness of 7mm (mm) and a diffuser plate PS material thickness of 2mm, for simplicity of calculation, the cover plate and diffuser plate have the same length and width dimensions, the weight reduction range is (cover plate weight + PS diffuser plate weight-glass diffuser plate weight)/(cover plate weight + PS diffuser weight): 1.58 × length/2.06 × length/width ═ 76.7%, or the weight of the new structure is 23.3% of the weight of the conventional structure.
The traditional design is glass cover plate + PS diffuser plate, the new structure has no glass cover plate, only has glass diffuser plate, so the reduction of weight is (traditional structure weight-new structure weight)/traditional structure weight. The thickness of the diffuser plate is unchanged.
Case two: the LCD display panel with the side-in type light-in backlight source structure is adopted, and a glass light guide plate is used for replacing a traditional light guide plate made of MS (polyacrylate) or PMMA (polymethyl methacrylate). Glass density 2.4g/cm3The elastic modulus is more than 68G Pa; MS Density 1.13g/cm3The elastic modulus is 1.32-1.42G Pa; PMMA density 1.18g/cm3And the elastic modulus is 2.35-3G Pa.
Effect on weight loss: weight of cover plate (length x width x thickness x 2.4 g/cm)3) + MS or PMMA (length X width X thickness X1.42 g/cm)3Or 1.18g/cm3) Light guide plate weight-glass light guide plate weight (length × width × thickness × 2.4 g/cm)3). Taking 65inch as an example, the thickness of the cover plate is 7mm, the thickness of the PMMA material of the light guide plate is 2mm, and for simple calculation, the length and width of the cover plate and the light guide plate are the same, the weight reduction range is (weight of the cover plate + weight of the PMMA light guide plate-weight of the glass light guide plate)/(weight of the cover plate + weight of PMMA diffusion): 1.436 × length width/1.916 × length × width 74.9%, or the weight of the new structure is 25.1% of the weight of the conventional structure.
For the function of thinning the structure, the direct type incident light backlight source and the side type incident light backlight source are not different: the conventional thickness range of the cover plate is generally 2 mm-10 mm, and the thickness of the optical adhesive layer is generally 0.3 mm. The thickness of the structure can be reduced by 2.3 mm-10.3 mm.
By applying the embodiment of the application, at least the following beneficial effects can be realized:
1. in the display panel 100, the first polarizer 110 located on the light exit side of the display panel 100 is made of a material having a pencil hardness of not less than 3H and not more than 9H, which has relatively excellent mechanical properties, so that the first polarizer 110 can provide sufficient scratch-resistant protection for the display panel 100, thereby preventing a display device in the display panel 100 from being scratched and damaged, and the first polarizer 110 can also provide a certain strength of support for the display panel 100, thereby reducing the probability of the display panel 100 being damaged, such as bent or even broken.
2. In the display panel 100 adopting the LCD display structure, the diffusion plate 142 or the light guide plate 144 in the backlight assembly 140 is made of a material having an elastic modulus not less than 68 gpa, so that the diffusion plate 142 or the light guide plate 144 has a certain strength, and can provide a certain strength for the whole display panel 100, thereby reducing the probability of the display panel 100 being damaged, such as bent or even broken.
3. In the touch display panel 200, the first polarizer 110 with a pencil hardness of not less than 3H and not more than 9H is used on the light exit side of the display panel 100 in the touch display panel 200, so that the first polarizer 110 can provide sufficient scratch-resistant protection for the display panel 100, thereby preventing a display device in the display panel 100 from being damaged by scratching, and the first polarizer 110 can also provide a certain strength of support for the display panel 100, thereby reducing the probability of the display panel 100 being bent or even broken or other damages.
4. In the touch display panel 200, with the help of the first polarizer 110, the display panel 100 is beneficial to realizing the elimination of the traditional cover plate structure, so that the cover plate structure can be omitted, the light and thin development of the touch display product is further promoted, the display picture is closer to the surface of the touch display product, the dislocation between the actual display position and the visual sense position is reduced or even eliminated, the dislocation between the touch point and the display point is reduced or even eliminated, and the touch precision is improved; the laminating process between the cover plate and the display device or the touch device can be omitted, the laminating light leakage problem is avoided, and the laminating cost is saved.
