Description
Technical Field
The invention relates to the technical field of display, in particular to a display device.
Background
Display devices such as mobile phone screens inevitably generate static electricity during the manufacturing process, but the static electricity may damage electronic components, especially display panels. The prior art adopts a silver paste dispensing mode to solve the problem of static dissipation. As shown in fig. 1, linear silver paste is coated between the upper polarizer and the TFT (thin film transistor) layer, and the silver paste connects the side surface of the upper polarizer and the TFT, so that static electricity on the electronic device is transferred to the ground layer in the TFT circuit layer through the upper polarizer and the silver paste, thereby realizing static dissipation and preventing the static electricity from adversely affecting the display panel.
The silver paste has various types, and is divided into Isotropic Conductive silver paste (ICAs) and Anisotropic Conductive silver paste (ACAs) according to the Conductive direction, the ICA refers to an Adhesive which is Conductive in all directions, and the silver paste can be widely applied to various electronic fields; ACA refers to an adhesive that is electrically conductive in one direction, such as the Z direction, and electrically non-conductive in the X and Y directions. Generally speaking, ACA is more demanding on equipment and processes, is less easy to implement, and is more used in the field of fine printing of plates, such as the printing of plates in Flat Panel Displays (FPDs).
The silver adhesive can be divided into room temperature cured conductive silver adhesive, medium temperature cured conductive silver adhesive, high temperature cured conductive silver adhesive, ultraviolet cured conductive silver adhesive and the like according to a curing system. The room temperature cured conductive silver adhesive is unstable, the volume resistivity is easy to change when the conductive silver adhesive is stored at room temperature, and metal particles are easy to oxidize when the high temperature cured conductive silver adhesive is cured at high temperature.

The conductive particles can be particles made of conductive materials, and can also be particles coated with the conductive materials.
In one embodiment of the present embodiment, the conductive member 2 may be a conductive layer, and the protective cover plate 1 is at least partially covered with the conductive layer, and the conductive layer is at least partially electrically connected to the transparent adhesive layer 4. In a preferred embodiment, the conductive layer is a transparent conductive layer, and covers the protective cover plate 1, and the transparent adhesive layer 4 is electrically connected to the transparent conductive layer. A transparent conductive layer, the composition of which may comprise: niobium oxide (Nb)2O3Or Nb2O5) Tantalum oxide (Ta)2O3Or Ta2O5) Antimony oxide (Sb)2O3Or Sb2O5) Tin oxide (SnO)2) Metal components, such as conductive metal elements of aluminum, zinc, silver, etc., may also be added. The transparent conductive layer of the embodiment can be Indium Tin Oxide (ITO), and has a light transmittance of more than 90% and good conductive performance.
In an embodiment of this embodiment, the transparent conductive layer may also be graphene (graphene), which is a new carbonaceous material with a two-dimensional cellular structure formed by tightly stacking single-layer carbon atoms, and is currently the thinnest and hardest nano material in the world, and is almost completely transparent, and only absorbs 2.3% of light, and has a resistivity of only about 10-6 Ω · cm, lower than copper or silver, and is the material with the smallest resistivity in the world, and can be prepared by a Chemical Vapor Deposition (CVD) method, a micro-mechanical separation method, an orientation attachment method, and the like. As the conductivity of the graphene is comparable to that of ITO, the light transmittance can reach 97%, and the mechanical strength and flexibility of the graphene are better than those of ITO transparent conductive materials. At present, the production cost is low when the graphene is prepared by the CVD method, high temperature and high pressure are not needed, and the manufacturing process is mature day by day.
When the thickness of the transparent conductive layer is too small, the resistance of the transparent conductive layer is increased, which is not beneficial to static electricity diversion and static electricity dissipation. When the thickness of the transparent conductive layer is too large, the light transmittance is reduced, and the display effect of the display screen is affected. The thickness of the transparent conductive layer may be 5-100 nm, and the thickness of the present embodiment may be preferably 10 nm.
As shown in fig. 4, the conductive layer entirely covers the protective cover 1, so that all static electricity on the protective cover 1 flows out through the conductive layer. When the area of the conductive layer is greater than or equal to the area of the transparent adhesive layer 4, the transparent adhesive layer 4 is in full contact connection with the conductive member 2, and when the area of the conductive member 2 is smaller than the area of the transparent adhesive layer 4, the transparent adhesive layer 4 is in partial contact connection with the conductive member 2. This embodiment may be preferred to optimize the static electricity dissipation effect by having the area of the conductive layer greater than or equal to the area of the transparent adhesive layer 4 and the transparent adhesive layer 4 in full contact with the conductive layer.
In one embodiment of this embodiment, as shown in fig. 6 to 9, the conductive member 2 is disposed around the peripheral edge of the protective cover 1, and the transparent adhesive layer 4 is electrically connected to the conductive member 2 through the conductor 9. The conductor can be a conductive metal wire or other materials with conductive capability, and the periphery of the conductive component 2 is connected to achieve the purpose of enhancing the conductive capability.
The conductive wires may be laid in a horizontal direction, a vertical direction, both horizontal and vertical directions, or in an inclined direction on the conductive member 2, as shown in fig. 6 to 9. The arrangement mode of the conductive member 2 and the conductive metal wires reduces the material of the conductive member 2 and saves the production cost under the condition of ensuring the conductive capability of the conductive member 2.
Because four corners of the display panel are easily damaged by electrostatic shock, the conductive structures are distributed on the edges of the periphery of the display panel, so that the corners of the display panel can be effectively prevented from being damaged by electrostatic shock.
This embodiment provides an implementation mode, as shown in fig. 5, the conductive member 2 is disposed around the peripheral edge of the protective cover 1, and the edge of the transparent adhesive layer 4 is connected to the conductive member 2. Thus, the static electricity on the protective cover 1 is conducted to the first ground 61 through the conductive member 2, and the static electricity of the color filter 31 is finally conducted to the first ground 61 through the polarizer 5, the transparent adhesive layer 4 and the conductive member 2; alternatively, the static electricity on the protective cover 1 is introduced to the second ground 62 through the conductive member 2, and the static electricity of the color filter 3 is finally introduced to the second ground 62 through the polarizer 5, the transparent adhesive layer 4, and the conductive member 2. In this arrangement, although the conductive capability of the conductive member 2 is slightly reduced, the static electricity dissipation can still be realized, and in this structure, the material consumption of the conductive structure 2 is less, so that the production and manufacturing cost of the conductive member 2 can be saved.
In the present embodiment, the color filter 31 is an optical filter for expressing color, which can precisely select the light wave of a small-range wavelength band to be passed through, and reflect or absorb the light wave of other undesired wavelength bands. The color filter comprises a black shading area and an RGB (red, green and blue) three-primary-color area. The RGB three-primary-color area comprises a red area, a green area and a blue area, each three areas form a pixel, one or more transmission light rays in the three areas are selected according to requirements to display the color of the area, and the three areas are mixed into corresponding colors. The thin-film transistor layer 32 is used to drive the rotation of the liquid crystal and control the display of each pixel, and is an important component of the liquid crystal display panel.

the conductive member 2 covers the light exit surface of the protective cover 1 facing the color filter 31.
Conductive particles are added into the optical cement to form the transparent adhesive layer 4 with stronger conductive capability.
The conductive member 2, the transparent adhesive layer 4, the polarizer 5, the color filter 31, and the thin film transistor layer 32 are connected in this order.
One end of the middle frame metal sheet is connected to the conductive member 2, and the other end is connected to a first ground line 61 on the main board of the display device.
Thus, the static electricity on the color filter 31 is transmitted to the conductive member 2 through the upper polarizer 5 and the transparent adhesive layer 4, the conductive member 2 transmits the static electricity to the first ground wire 61 through the middle frame metal piece, and the static electricity on the protective cover plate 1 is transmitted to the first ground wire 61 through the conductive member 2 through the middle frame metal piece, thereby effectively achieving static electricity dissipation.
The embodiment also provides another method for producing a display device, which comprises the following steps:

Conductive particles are added into the optical adhesive and the silicone adhesive, so that the optical adhesive and the silicone adhesive have strong conductive capability, and the transparent bonding layer 4 and the second conductive piece 8 with the conductive capability are respectively formed.
Sequentially connecting the conductive component 2, the transparent adhesive layer 4, the polarizer 5, the color filter 31 and the thin film transistor layer 32;
silicone adhesive is added between the conductive member 2 and the second ground 62 on the thin-film transistor layer 32, and electrical connection is made through the second conductive component 8.
