Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1, the display screen 100 according to the present invention includes a transparent protection plate 10, an optical film 20, an ink layer 30, a functional layer 40, and a display layer 50, which are sequentially stacked, wherein the transparent protection plate 10 has a visible window 11 and a non-visible window 12, the non-visible window 12 surrounds the visible window 11, the optical film 20 is stacked on the transparent protection plate 10, and has a first transparent layer 21 corresponding to the visible window 11, and a second transparent layer 22 corresponding to the non-visible window 12. The ink layer 30 is stacked on the side of the optical film 20 away from the transparent protective plate 10 and covers the non-visible window 12. The functional layer 40 comprises a visible functional layer 41 corresponding to the visible window 11 and a non-visible functional layer 42 corresponding to the visible window 12. The visible functional layer 41 is stacked on the first light-transmitting layer 21, and the non-visible functional layer 42 is stacked on the ink layer 30. The functional layer 40 may be an optical adhesive, so that the display layer 50 is attached to the transparent protective plate 10; the display panel 100 may also be a touch layer for increasing a touch function of the display panel 100, and may also be a polarizer for enhancing a display effect of the display panel 100. The display layer 50 is stacked on a side of the functional layer 40 facing away from the optical film 20, and includes a visible region 50a and a non-visible region 50b corresponding to the visible window 11 and the non-visible window 12, respectively.
A visible light transmitting layer 41a is formed by the visible functional layer 41 and the first light transmitting layer 21, and the refractive index of the visible light transmitting layer 41a is the same as that of the second light transmitting layer 22, so that the reflection intensity increment of the non-visible region 50b is greater than that of the visible region 50a, and further the reflection intensity of the non-visible region 50b is approximately consistent with that of the visible region 11, thereby realizing that the appearance surface of the display screen 100 presents a color integration effect under the condition of power failure, and enhancing the visual effect of the display screen 100. It is understood that the display screen 100 is applied to a terminal device to display image information for the terminal device. The terminal equipment can be a mobile phone, a notebook computer, a tablet computer, an electronic reader, an electronic photo album and the like.
In this embodiment, the transparent protection plate 10 is a transparent glass plate, and the thickness of the transparent protection plate 10 is 0.3 to 2.0mm, preferably 1.5 mm. The transparent protective plate 10 includes an upper surface 10a and a lower surface 10b which are oppositely disposed. The upper surface 10a may serve as an external appearance surface of the display panel 100, and the lower surface 10b is plated with the reflective film 20. In the case where the display screen 100 is powered off, the color of the display layer 40 when powered off can be observed through the viewing window 11, and specifically, the light emitted from the display layer 40 is partially reflected by the transparent protective plate 10 and the viewing function layer 41a, so that there is distortion in observing the display layer 40. Similarly, the color of the ink layer 30 can be observed through the non-visible window 12, and specifically, a part of the light emitted from the ink layer 30 is reflected by the transparent protective plate 10 and the second light-transmitting layer 22, so that the observation of the ink layer 30 is also distorted. With the refractive indexes of the second light-transmitting layer 22 and the visual functional layer 41a being the same, that is, the reflection intensities of the second light-transmitting layer 22 and the visual functional layer 41a being the same, the distortion degree of the ink layer 30 viewed from the non-visual window 12 is the same as the distortion degree of the display layer 40 viewed from the visual window 11. On this basis, the color of the ink layer 30 is adjusted to be the same as the color of the display layer 50 when the power is off, so that the ink layer 30 is observed on the upper surface 10a of the transparent protective plate 10, and the display layer 50 is observed in a contrasting manner, thereby presenting no differentiation, so that the ink layer 30 and the display layer 40 cannot be distinguished when the power is off on the appearance surface of the display screen 100, presenting an integral effect, and enhancing a visual effect. In other embodiments, the transparent protective plate 10 may also be organic resin glass.
In this embodiment, the optical film 20 is plated on the lower surface 10b by a plating process, and covers the visible window 11 and the non-visible window 12. Specifically, the first light-transmitting layer 21 corresponds to the visible window 11, and the second light-transmitting layer 22 corresponds to the non-visible window 12. The first light-transmitting layer 21, the visible window 11 and the visible functional layer 412 together refract the observation light of the display layer 50, and jointly affect the observation effect of the display layer 50. The second transparent layer 22 and the non-visible window 12 jointly refract the observation light of the ink layer 30, and jointly affect the observation effect of the ink layer 30. Since the refractive index of the visible window 11 is the same as that of the non-visible window 12, by setting the refractive indexes of the first light-transmitting layer 21 and the second light-transmitting layer 22 to be different, the refractive index of the visible light-transmitting layer 41a is the same as that of the second light-transmitting layer 22, so that the visual effect of the second light-transmitting layer 22 on the ink layer 30 is the same as that of the visible light-transmitting layer 41a on the non-visible region 50 b. More specifically, the refractive index of the first light-transmitting layer 21 is greater than the refractive index of the second light-transmitting layer 22, and the reflection intensity of the first light-transmitting layer 21 to light is less than the reflection intensity of the second light-transmitting layer 22 to light, so that the reflection intensity of the first light-transmitting layer 21 and the visible functional layer 41 to light is consistent with the reflection intensity of the second light-transmitting layer 22 to light. The first light-transmitting layer 21 and the second light-transmitting layer 22 are subjected to film coating according to a film structure model obtained by using a film system design on a computer, so that the optical film 20 having the first light-transmitting layer 21 and the second light-transmitting layer 22 is obtained. By plating the optical film 20 on the lower surface 10b, the optical film 20 can achieve optical effects on two different areas, thereby reducing the steps of the coating process, reducing labor force, improving the visual effect of the display screen 100, and reducing labor cost. The thickness of the optical film 20 is less than or equal to 3 μm, preferably 2.5 μm. The optical film 20 may be added with a black pigment, so that the black color of the ink layer 30 observed from the non-visible window 12 is adjustable, and the black colors observed from the visible window 11 and the non-visible window 12 are more consistent, thereby achieving the effects of simple manufacturing of the display screen 100 and cost reduction. In other embodiments, the thickness of the reflective film 20 may also be 2.0 μm.
In this embodiment, the ink layer 30 is printed on the side of the reflective film 20 away from the lower surface 10b by a silk-screen printing process, that is, the medium contacting the observation surface of the ink layer 30 is the second light-transmitting layer 22. The viewing effect of the ink layer 30 is influenced by the second light transmitting layer 22. Specifically, the ink layer 30 is formed by applying a common black ink on a screen printing plate, printing the screen printing plate on the reflective film 20, and then baking and curing the screen printing plate. The ink layer 30 is made of black ink with uniform specification, and the black of the ink layer 30 can be adjusted by adjusting the black of the non-visible window 12, so that the black of the ink layer 30 is prevented from being adjusted, the ink with the same specification is used when the ink layer 30 is printed every time, the cost of the display screen 100 is reduced, and labor is saved. In other embodiments, the black color value of the ink layer 30 can be fine-tuned, so that the visual appearance of the display screen 100 is better.
In this embodiment, the functional layer 40 includes a visible functional layer 41 corresponding to the visible window 11 and a non-visible functional layer 42 corresponding to the non-visible window 12. The visible functional layer 41 is attached to the second light transmitting layer 22, facing away from the visible functional layer 41. The non-visible functional layer 42 is attached to the ink layer 30, and the non-visible functional layer 42 is shielded by the ink layer 30, so that the non-visible functional layer 42 is not visible. The thickness of the functional layer 40 is greater than the thickness of the ink layer 30, and generally, the thickness of the functional layer 40 is 0.02mm to 2.0 mm. It is understood that light irradiated to the display layer 50 through the functional layer 40 is refracted and reflected, and light emitted from the display layer 50 through the functional layer 40 is also refracted and reflected. The functional layer 40 affects the observation of the display layer 50, and the functional layer 40 has a predetermined refractive index, so that the reflection intensity of the reflective film 20 on the ink layer 20 is the same as the reflection intensity of the functional layer 40 on the display layer 50 by adjusting the refractive index of the reflective film 20, thereby avoiding the replacement of the functional layer 40 and the redesign of the functional layer 40, and achieving the effects of enhancing the visual effect of the display screen 100, saving labor, improving yield and reducing cost. In other embodiments, the functional layer 40 may also be a stack of multiple light-transmissive layers as needed to achieve multiple functions of the display screen 100.
In this embodiment, the display layer 50 includes a visible region 50a corresponding to the visible window 11 and a non-visible region 50b corresponding to the non-visible window 12. The visible region 50a is correspondingly attached to the visible functional layer 41, and the non-visible region 50b is correspondingly attached to the non-visible functional layer 42. The non-visible area 50b is obscured by the ink layer 30, and the non-visible area 50b is not visible. The medium with which the viewing surface of the visible area 50a is in contact is the visual functional layer 41, whereby the visual functional layer 41 affects the visual effect of the visible area 50 a. The display layer 50 is a liquid crystal display module with uniform specification, the display layer 50 presents specific black under the condition of power failure, and the black visual effect of the display layer 50 is generally unadjustable, so that the adjustment of the black visual effect of the ink layer 30 is realized by adjusting the black color value of the reflection film 20, so that the black visual effect of the ink layer 30 is consistent with that of the display layer 50, and thus, when the display screen 100 is observed under the condition of power failure, the visual effect of the visible area 50a is not different from that of the ink layer 30, the change or redesign of the display layer 50 is avoided, the visual effect of the display screen 100 is improved, the production cost is reduced, and the labor force is saved. In other embodiments, the display layer 50 may also be an organic electroluminescent layer that can realize dual-sided light emission.
Further, the display screen 100 further includes an antireflection film 60, and the antireflection film 60 is stacked on the transparent protective plate 10 and covers the visible window 11 and the non-visible window 12.
in this embodiment, the antireflection film 60 is plated on the upper surface 10a of the transparent protection plate 10, and the antireflection film 60 is made of magnesium fluoride, titanium oxide, lead sulfide, lead selenide, and other materials. The antireflection film 60 reduces the intensity of light reflected by the upper surface 10a and simultaneously reduces the intensity of light reflected by the non-visible window 12, that is, simultaneously increases the intensity of transmitted light in the visible region 11 and the intensity of transmitted light in the non-visible region 12. Thereby, the display screen 100 can be observed more clearly under the power-off condition, and the overall visual effect of the display screen 100 is enhanced. Under the effect of the antireflection film 60, the black color of the display layer 50 observed from the visible region 11 is closer to the real black color of the display layer 50, and the black color of the ink layer 30 observed from the non-visible region 12 is also closer to the real black color of the ink layer 30, so that the whole displayed black color of the display screen 100 is more real, and the visual effect of the display screen 100 is increased. In other embodiments, the antireflection film 60 may also be plated on the lower surface 10b of the transparent protection plate 10, and the optical film 20 is plated on a side of the antireflection film 60 away from the transparent protection plate 10.
further, referring to fig. 2, a touch layer 70 is stacked on the optical film 20 near the transparent protective plate 10, and the touch layer 70 covers the first light-transmitting layer 21 and the second light-transmitting layer 22.
In this embodiment, the display screen 100 (see fig. 1) is a touch display screen, and the touch layer 70 corresponds to the visible region 51 and the non-visible region 52 at the same time, that is, the observation light of the display layer 50 and the ink layer 30 corresponding to the display region 51 needs to penetrate through the touch layer 70. The light reflection intensity of the touch layer 70 to the ink layer 30 and the display layer 50 corresponding to the visible area 51 is the same, and the touch layer 70 is more favorable for the consistency of the visual effect of the ink layer 30 and the display layer 50.
in a preferred embodiment, the display screen 100 is an OGS (One Glass Solution, integrated touch) touch screen, that is, the touch layer 70 is integrated with the transparent protective plate 10. Specifically, the transparent protection plate 10 includes a transparent glass layer 101, and the touch layer 70 is embedded on one side of the transparent glass layer 101 close to the optical film 20. The upper surface 10a is disposed on the transparent glass layer 101, and the lower surface 10b is disposed on the touch layer 70. Specifically, the touch layer 70 is formed by plating an indium tin oxide film on the side of the transparent glass layer 101 close to the optical film 20, and then performing photolithography and plating processes. The touch layer 70 is integrated with the transparent protective plate 10, and the touch layer 70 is attached to the transparent protective plate 10, so that on one hand, an optical adhesive layer and a glass protective plate are reduced, the cost is reduced, and the labor force is saved; and on the other hand makes the display screen 100 thinner.
In another embodiment, referring to fig. 3, a touch layer 241 is disposed in the functional layer 240.
in this embodiment, the display screen 100 is a GFF (Glass-Film, double plastic layer touch screen) touch screen, and the functional layer 240 is fully attached to the transparent protection plate 210, that is, the touch layer 241 is integrally disposed on the transparent protection plate 210. Specifically, the touch layer 241 may be manufactured in advance as a thin film product, and then the touch layer 241 is completely attached to the transparent protection plate 210. The process of integrating the touch layer 241 with the transparent protection plate 210 is to plate the optical film 20 on the lower surface 210b of the transparent protection plate 210, then screen-print the ink layer 30 corresponding to the second light-transmitting layer 22, and then attach the touch layer 241, which has been made into a thin film product, to the optical film 20 and cover the visible window 11 and the non-visible window 12.

The first conductive layer 2411 is integrated with the transparent protection plate 210 through an optical adhesive. The functional layer 240 is integrated with the transparent protection plate 210, so that no gap is formed between the functional layer 240 and the transparent protection plate 210, the light transmittance of the display screen 100 corresponding to the visual window 11 is increased, the reflection intensity of the display screen 100 corresponding to the visual window 11 is effectively reduced, and the visual effect of the display screen 100 is enhanced.
