As shown in fig. 1 to 4, the present embodiment provides a display device, which can be applied to various mobile terminals (e.g. mobile phones, tablet computers) with flexible display requirements. The display device comprises a curling storage component 1, a flexible display screen 2 and a supporting component 3, wherein the curling storage component 1 is used for curling the flexible display screen 2, and the supporting component 3 is used for supporting the flexible display screen 2, and meanwhile, curling action of the flexible display screen 2 is not hindered.
Specifically, the curl storage assembly 1 includes a first curl storage rail 11 and a second curl storage rail 12 arranged in parallel at intervals, the first curl storage rail 11 having a first storage groove 111 extending in the curl direction of the first curl storage rail 11, and the second curl storage rail 12 having a second storage groove extending in the curl direction of the second curl storage rail 12. The two sides of the flexible display screen 2 are respectively provided with a first protruding portion 21 slidably fitted with the first receiving groove 111 and a second protruding portion 22 slidably fitted with the second receiving groove. In the curling and unfolding process of the flexible display screen 2, the first bulge 21 is in sliding fit with the first accommodating groove 111, and the second bulge 22 is in sliding fit with the second accommodating groove, so that the curling and unfolding action smoothness of the flexible display screen 2 is high, automatic curling and unfolding of the flexible display screen 2 is easy to realize, and the use experience of a user is improved.
The support assembly 3 includes a support base 31 disposed at a distance from the flexible display 2, and a sliding support 32 slidably engaged with the support base 31, the sliding support 32 being connected to the bottom of the flexible display 2. Under the sliding fit action of the sliding support piece 32 and the supporting bottom plate 31, the sliding support piece 32 can not influence the curling and unfolding actions of the flexible display screen 2, can effectively support the bottom of the flexible display screen 2, can effectively avoid screen abrasion caused by the fact that the middle part or other non-edge parts of the flexible display screen 2 collapse to be in contact with other parts of the mobile terminal, and prolongs the service life of products.
Optionally, a sliding groove is provided on the supporting bottom plate 31, the sliding support 32 includes a first sliding portion 321 and a second sliding portion 322 that are connected, the first sliding portion 321 is slidably disposed between the flexible display screen 2 and the supporting bottom plate 31, and the second sliding portion 322 is slidably disposed in the sliding groove. By providing the slide groove on the support base plate 31, the influence of the installation space required for the slide support 32 on the thickness of the entire display device can be reduced. The sliding support 32 is divided into two parts, one part is a first sliding part 321, the other part is a second sliding part 322, and the first sliding part 321 can effectively ensure that a large enough interval exists between the flexible display screen 2 and the support bottom plate 31, so that the flexible display screen 2 is prevented from being scratched and worn due to contact with the support bottom plate 31. Because the second sliding portion 322 is slidably disposed in the sliding groove, the sliding groove can limit the second sliding portion 322, so as to prevent the flexible display screen 2 from shaking left and right in the curling process.
To avoid separation of the second sliding portion 322 and the chute, the cross section of the second sliding portion 322 and the chute may alternatively be inverted T-shaped or trapezoidal. The side wall of the chute applies a force to the second sliding part 322 to compress the second sliding part 322, so as to prevent the second sliding part 322 from being separated from the chute.
In this embodiment, the first sliding portion 321 and the second sliding portion 322 may be integrally formed, which is convenient for mass production. In other embodiments, the first sliding portion 321 and the second sliding portion 322 may be spliced into an integral structure, which is convenient for maintenance and replacement.
Optionally, the bottom of the flexible display screen 2 is provided with a first magnetic member 4, and the supporting base plate 31 is provided with a second magnetic member 5 having the same magnetic properties as the first magnetic member 4. Because the first magnetic part 4 and the second magnetic part 5 have the same magnetism and generate repulsive force, the curling and unfolding actions of the flexible display screen 2 are not affected, the bottom of the flexible display screen 2 can be effectively supported, screen abrasion caused by the fact that the middle part or other non-edge parts of the flexible display screen 2 collapse to be in contact with other parts of the mobile terminal can be effectively avoided, and the service life of products is prolonged. The first magnetic member 4 may be disposed in an area which cannot be covered by the sliding support 32 as a complement to the supporting force of the area. The first magnetic element 4 and the second magnetic element 5 can be respectively in flat bar-shaped structures, and the thickness influence of the installation space required by the first magnetic element 4 and the second magnetic element 5 on the whole display device can be reduced.
In order to further reduce the influence of the installation space required for the second magnetic member 5 on the thickness of the entire display device, optionally, a receiving groove is provided on the supporting base plate 31, and the second magnetic member 5 is disposed in the receiving groove.
Optionally, the first magnetic member 4 is adhered to the lower surface of the flexible display screen 2; and/or the second magnetic member 5 is adhered to the upper surface of the support base plate 31. The first magnetic piece 4 and the second magnetic piece 5 are installed in an adhering mode, the process is simple, and the processing and manufacturing cost of the whole display device is reduced conveniently.
To avoid the sliding support 32 affecting the crimping action of the flexible display 2, the sliding support 32 is alternatively made of a flexible material. That is, the sliding support 32 may curl with the flexible display 2, avoiding interference that may cause the flexible display 2 to fail to curl or curl.
The sliding support 32 may be made of the following flexible materials: polyvinyl alcohol (PVA), polyester (PET), polyimide (PI), polyethylene naphthalate (PEN), paper sheets, textile materials, and the like. The polyimide material has the advantages of high temperature resistance, low temperature resistance, chemical resistance and good electrical characteristics, is the material with the basic potential of flexible electronics, and only the high temperature resistance is considered in the selection of the flexible substrate, but the light transmittance, the surface roughness and the material cost of the flexible substrate are all factors to be considered. Polydimethylsiloxane (PDMS) is also a widely accepted flexible material, and its advantages include convenience and availability, stable chemical properties, transparency, good thermal stability, etc. The distinct nature of the adhesive and non-adhesive regions, particularly under uv light, allows the surface to readily adhere to electronic materials. PET has low conversion temperature of about 70-80 ℃, but has low price and good light penetrability, and is a material with high cost performance of transparent conductive film.
Optionally, a sliding support 32 is glued to the bottom of the flexible display 2. The sliding support 32 is mounted in an adhesive manner, so that the process is simple, and the processing and manufacturing cost of the whole display device is reduced.
Alternatively, the sliding support 32 is provided in plurality in the width direction of the flexible display screen 2. The sliding support 32 may be a long strip structure, and a plurality of sliding supports 32 with long strip structures are disposed along the width direction of the flexible display screen 2, so as to cover most areas of the flexible display screen 2 and effectively support the bottom of the flexible display screen 2. The sliding support members 32 may also be in a block structure, and a plurality of sliding support members 32 are distributed at the bottom of the flexible display screen 2 in an array, so as to cover most of the area of the flexible display screen 2 and effectively support the bottom of the flexible display screen 2.
The first curl storage rail 11 and the second curl storage rail 12 are disposed in parallel in opposition, and a space between the first curl storage rail 11 and the second curl storage rail 12 forms a storage rail for storing the flexible display screen 2. The ends of the first curled accommodating rail 11 and the second curled accommodating rail 12 are respectively provided with groove inlets of the first accommodating groove 111 and the second accommodating groove, so that the first protruding part 21 and the second protruding part 22 can conveniently enter the first accommodating groove 111 and the second accommodating groove respectively, and the first protruding part 21 and the second protruding part 22 can move along the grooves where the first protruding part 21 and the second protruding part 22 are located to drive the flexible display screen 2 to curl and be accommodated in the accommodating track and drive the flexible display screen 2 to extend out of the accommodating track.
The first and second protrusions 21 and 22 on both sides of the flexible display screen 2 have a size in the thickness direction of the flexible display screen 2 larger than the thickness of the flexible display screen 2. The first boss 21 and the second boss 22 are housed in the first housing groove 111 and the second housing groove of the first curl housing rail 11 and the second curl housing rail 12, the dimensions of the first curl housing rail 11 and the second curl housing rail 12 in the thickness direction of the flexible display screen 2 are larger than the thickness of the flexible display screen 2, and when the first boss 21 and the second boss 22 are curled and housed in the first housing groove 111 and the second housing groove, if the first curl housing rail 11 and the second curl housing rail 12 do not overlap, the flexible display screen 2 is curled and housed in the housing rail in a single layer, and there is no problem of contact and scratch; if the flexible display screen 2 is curled and stored in the storage track, the first protruding portion 21 and the second protruding portion 22 have larger sizes in the thickness direction of the flexible display screen 2, so that gaps exist between the flexible display screens 2 between adjacent layers, the problems of contact and scraping between the adjacent layers of the flexible display screen 2 are avoided or minimized, and the flexible display screen 2 is protected.
As for the specific form of the first curl storage rail 11 and the second curl storage rail 12, it is possible that the curl first curl storage rail 11 and the second curl storage rail 12 overlap at least in part, the first curl storage rail 11 and the second curl storage rail 12 are stacked in the overlapping position with a space between adjacent layers. When the flexible display screen 2 is curled and accommodated in the accommodating tracks formed between the first curled accommodating guide rail 11 and the second curled accommodating guide rail 12 and between the first curled accommodating guide rail 11 and the second curled accommodating guide rail 12, the gap between adjacent layers of the flexible display screen 2 at the overlapped position is larger, so that the problems of contact and scraping between the flexible display screens 2 between the adjacent layers are further avoided or reduced to the greatest extent, and the flexible display screen 2 is protected; meanwhile, the flexible display screen 2 has smaller curling degree, and damage of the flexible display screen 2 caused by excessive curling is reduced. Specifically, the first and second curled receiving rails 11, 12 may be helical rail structures.
In order to achieve the accommodation of the flexible display 2 in the accommodation track or the extension of the flexible display 2 from the accommodation track, the curl accommodation assembly 1 optionally further comprises a curl drive shaft 13 and a flexible connection 14, the flexible display 2 being connected to the curl drive shaft 13 by the flexible connection 14. The side edge of the flexible display screen 2 and the curled driving shaft 13 are fixed by a flexible connecting piece 14; the flexible connecting piece 14 is wound on the surface of the curled driving shaft 13 and drives the first protruding portion 21 and the second protruding portion 22 to move along the first accommodating groove 111 and the second accommodating groove respectively to curl and accommodate the flexible display screen 2 in the accommodating track and drive the flexible display screen 2 to extend out of the accommodating track. The curl driving shaft 13 and the flexible display screen 2 are fixed, and the existence of the curl driving shaft 13 enables a user to drive the first protruding part 21 and the second protruding part 22 to respectively move along the first accommodating groove 111 and the second accommodating groove by operating the curl driving shaft 13 to move along the curl direction of the first curl accommodating guide rail 11 and the second curl accommodating guide rail 12, so that the flexible display screen 2 is curled and accommodated in the accommodating track and the flexible display screen 2 stretches out of the accommodating track to be more convenient to operate.
In order to better protect the flexible display 2, the display device further comprises a hollow shaft, in which the receiving rail is located. The shaft barrel has a boss entrance for the first boss 21 and the second boss 22 to enter the first receiving recess 111 of the first curl receiving rail 11 and the second receiving recess of the second curl receiving rail 12, respectively, with a flexible display 2 entrance for the flexible display 2 to enter the shaft barrel therebetween. The shaft cylinder is provided with a bulge part inlet and a flexible display screen 2 inlet, so that the flexible display screen 2 can enter and exit the shaft cylinder; the existence of the shaft barrel can protect the flexible display screen 2 which is curled and accommodated in the accommodating track.
In order to reduce the resistance to movement of the first and second protrusions 21 and 22 along the first and second receiving grooves 111 and 22, respectively, the friction coefficient of the material of the first and second protrusions 21 and 22 is less than 0.5; and/or the friction coefficient of the material of the inner walls of the first receiving groove 111 and the second receiving groove is less than 0.5. Thus, when the first protruding portion 21 and the second protruding portion 22 move along the first accommodating groove 111 and the second accommodating groove, respectively, the resistance is relatively small, and the process of accommodating the flexible display screen 2 in the accommodating track in a curled manner and extending the flexible display screen 2 from the accommodating track is relatively smooth.
Note that, the flexible display screen 2 refers to a flexible OLED (Organic Light-Emitting Diode). The OLED is thin and can be mounted on flexible materials such as plastic or metal foil. Instead of glass, plastic makes the display screen more durable and lighter. The flexible OLED panel is concave from top to bottom, and the bending radius can reach 700 millimeters. The OLED adopts a plastic substrate instead of a common glass substrate, and a protective film is stuck on the back surface of the panel by means of a thin film packaging technology, so that the panel becomes bendable and is not easy to break.
The OLED device is composed of a substrate, a cathode, an anode, a Hole Injection Layer (HIL), an Electron Injection Layer (EIL), a Hole Transport Layer (HTL), an Electron Transport Layer (ETL), an Electron Blocking Layer (EBL), a Hole Blocking Layer (HBL), an emission layer (EML), and the like. Wherein, the base plate is the basis of the whole device, all functional layers need to be evaporated on the base plate of the device; glass is typically used as the substrate for the device, but if a flexible OLED device is desired to be fabricated, other materials such as plastics and the like are required as the substrate for the device. The anode is connected with the positive electrode of the externally applied driving voltage of the device, holes in the anode can move towards the light-emitting layer in the device under the drive of the externally applied driving voltage, and the anode needs to have certain light transmittance when the device works, so that light emitted from the inside of the device can be observed by the outside; the most commonly used material for the anode is ITO.
The hole injection layer can modify the anode of the device and can enable holes from the anode to be smoothly injected into the hole transport layer; the hole transport layer is responsible for transporting holes to the light emitting layer; the electron blocking layer can block electrons from the cathode at the interface of the light emitting layer of the device, so that the concentration of electrons at the interface of the light emitting layer of the device is increased; the light-emitting layer is a place where the device electrons and holes are recombined to form excitons and then the excitons de-excite light; the hole blocking layer can block holes from the anode at the interface of the device light-emitting layer, so that the probability of recombination of electrons and holes at the interface of the device light-emitting layer is improved, and the light-emitting efficiency of the device is increased; the electron transport layer is responsible for transporting electrons from the cathode into the light emitting layer of the device; the electron injection layer plays a role in modifying the cathode and transmitting electrons to the electron transmission layer; electrons in the cathode move toward the light-emitting layer of the device under the drive of an applied driving voltage of the device, and then recombine with holes from the anode at the light-emitting layer.
Compared with the traditional screen, the flexible display screen 2 has obvious advantages, is lighter in size and lower than the original device in power consumption, is favorable for improving the endurance of equipment, and is also greatly higher than the traditional screen in durability based on the characteristics of being bendable and good in flexibility, so that the probability of accidental damage of the equipment is reduced. The screen of the folding screen is required to be folded for 20 ten thousand times and is a flexible screen with higher flexibility requirement, and the structure of the screen also needs to be designed independently.
In the display device provided by the embodiment, in the curling and unfolding process of the flexible display screen 2, the sliding fit between the first protruding part 21 and the first accommodating groove 111 and the sliding fit between the second protruding part 22 and the second accommodating groove are used for guiding, so that the smooth degree of the curling and unfolding action of the flexible display screen 2 is high, the automatic curling and unfolding of the flexible display screen 2 is easy to realize, and the use experience of a user is improved; under the sliding fit action of the sliding support piece 32 and the supporting bottom plate 31, the sliding support piece 32 can not influence the curling and unfolding actions of the flexible display screen 2, can effectively support the bottom of the flexible display screen 2, can effectively avoid screen abrasion caused by the fact that the middle part or other non-edge parts of the flexible display screen 2 collapse to be in contact with other parts of the mobile terminal, and prolongs the service life of products.
The embodiment also provides a mobile terminal, including foretell display device, mobile terminal can be cell-phone, panel computer and other wearable equipment, the bottom of this mobile terminal's flexible display screen 2 has obtained effective support, can effectively avoid the middle part of flexible display screen 2 or other non-edge part to collapse and with mobile terminal's other parts contact cause the screen wearing and tearing, product life has been prolonged, the product is novel, the degree of identification is high, application crowd is wide, application scene is abundant, the screen curls and expands smooth nature of action, convenient operation, not fragile, long service life, it is good to use.
