It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
As shown in fig. 3, a schematic structural diagram of a foldable display device provided in an embodiment of the present application is shown, where the foldable display device mainly includes:
at least two display panels 31, at least two display panels 31 (two display panels are shown in fig. 3 and marked with B1 and B2) are sequentially and respectively spliced together through connecting parts 32; the size of the display panels 31 spliced together is not limited, and may be display panels 31 having different or the same size, but the thickness of the display panels spliced together should be the same in order to ensure the viewing effect after splicing.
The connecting portion 32 is located in a splicing region (shown by a dashed line box in the figure) of any two adjacent display panels 31, and the connecting portion 32 at least includes a first matching portion 33 disposed on the first display panel 31a and a second matching portion 34 disposed on the second display panel 31 b;
the first matching portion 33 and the second matching portion 34 are both in a semicircular structure, and the first matching portion 33 and the second matching portion 34 are matched with each other and slide outside the splicing area to realize folding of the display device. In the present application, the radius of the semicircular structures of the first matching portion 33 and the second matching portion 34 is the same as the thickness of the display panel, and the center of the circle of the first matching portion 33 and the center of the circle of the second matching portion 34 are both located on the folding axis a. On one hand, when the display panels spliced together are not turned over, the first matching part 33 and the second matching part 34 are both limited in the display panels, and the display panels spliced together can be spliced as seamlessly as possible; on the other hand, the display panels spliced together can be ensured to be turned over at a specific angle around the turning-over axis A all the time in the turning-over process. Therefore, seamless splicing of the display panels in the folding display device is guaranteed, and the overall picture effect in the folding process is improved.
Through this technical scheme, utilize first cooperation portion and the second cooperation portion that sets up respectively on adjacent display panel, mutually support outside the splicing region and slide the folding book that realizes display device, not only provided a new connection structure that turns over, moreover, the foldable display device who utilizes this connection structure concatenation can also avoid among the prior art because support that the splicing display panel used etc. to showing the positive influence and reduce the problem of watching the visual angle. The foldable display device provided by the application can also realize folding at any angle, and the display panel after being stably fixed and folded.
Alternatively, in the present application, as shown in fig. 3, the first fitting part 33 includes a first inner fitting part 33a embedded inside the first display panel 31a and a first outer fitting part 33b exposed to the outside; the second fitting portion 34 includes a second inner fitting portion 34a embedded inside the second display panel 31b and a second outer fitting 34b exposed outside. In fact, considering that two display panels spliced together need to be folded at any angle, the first matching part 33 and the second matching part 34 both have external fittings exposed to be inserted into the internal fittings on the opposite side.
Optionally, the first inner fitting 33a has the same arc length as the first outer fitting 33b, and the second inner fitting 34a has the same arc length as the second outer fitting 34 b. Therefore, the first inner matching part 33a and the first outer fitting 33b, and the second inner matching part 34a and the second outer fitting 34b are all one-fourth arc length, so that the folding operation at any angle can be realized.
Based on the structure that can be realized, the structure of the foldable display device related to the present application under different folding states is slightly different:
when any two display panels spliced together are in a tiled state, the first external fitting is inserted into the second internal fitting part, and the second external fitting is inserted into the first internal fitting part;
specifically, referring to fig. 4(a), when the folding angle of the display panel B1 and the display panel B2 that are spliced together is 0 °, the display panel B1 and the display panel B2 are tiled together and the opposite spliced ends are completely spliced together; the first external fitting 33B of the display panel B1 is inserted into the second internal fitting 34a of the display panel B2, and the second external fitting 34B of the display panel B2 is inserted into the first internal fitting 33B of the display panel B1.
When any two display panels spliced together are in an open state, the first external fitting and the second external fitting are at least partially overlapped;
specifically, referring to fig. 4(B), when the folding angle of the display panel B1 and the display panel B2 that are spliced together is 90 °, the display panel B1 and the display panel B2 are perpendicular, and the opposite spliced ends are spliced only at the folding axis a; the first outer fitting 33B of the display panel B1 completely overlaps the second outer fitting 34B of the display panel B2. It should be noted that, in this folding state, the connection portion 32 is located outside the splicing area of the foldable display device, so that the front viewing angle of the display is not affected, and the user experience is ensured.
When any two display panels spliced together are in a folded state, the exposed end of the first external fitting is connected with the exposed end of the second external fitting;
specifically, referring to fig. 4(c), when the folding angle of the display panel B1 and the display panel B2 that are spliced together is 180 °, the display panel B1 and the display panel B2 are folded together; the end of the first external fitting 33B of the display panel B1 exposed to the outside is connected to the end of the second external fitting 34B of the display panel B2 exposed to the outside. Similarly, in this folding state, the connecting portion 32 is located outside the splicing area of the foldable display device, so that the front viewing angle of the display is not affected, and the user experience is ensured.
Optionally, the first engaging portion and the second engaging portion are both groove-shaped or slide rail-shaped. The application does not limit the concrete structure of the groove or the slide rail, and the first matching part and the second matching part can be matched with each other to slide as long as the first matching part and the second matching part can be matched with each other.
Optionally, the first matching portion is in a hollow tubular shape, the second matching portion is in a solid columnar shape, a certain gap exists between the portion, located in the display panel, of the second matching portion and the display panel, the thickness of the gap is larger than the wall thickness of the hollow tubular shape of the first matching portion, and the outer diameter of the second matching portion is smaller than the inner diameter of the first matching portion, so that the second matching portion can be matched with the first matching portion to stretch into the display panel. Thus, in the first matching part, the first external fitting is a hollow pipe exposed outside, and the first internal fitting part can be understood as a quarter arc through hole drilled in the display panel; similarly, in the second matching portion, the second external component is an exposed solid column, and the second internal matching portion may be understood as the solid column extending into the display panel.
Optionally, in this application, the inner wall of first cooperation portion and the outer wall of second cooperation portion all have line structure or gear structure, or, the outer wall of first cooperation portion and the inner wall of second cooperation portion all have line structure or gear structure. The grain structure or the gear structure is used for assisting the first matching part and the second matching part to carry out angle fixation after being turned over to a desired angle. Further, friction between the first fitting portion and the second fitting portion can be increased. In fact, consider that in this application, mutually support between first cooperation portion and the second cooperation portion and slide, after reaching the expected angle of turning over, the accessible buckle is fixed current state of turning over. Wherein, the buckle can set up on first cooperation portion or on the second cooperation portion, also can slide between first cooperation portion and second cooperation portion in a flexible way, and its specific joint position can be according to user's demand optional.
Optionally, a preferred implementation structure may be that the first mating portion and the second mating portion are both connected to a voltage, and the first mating portion is in contact with the second mating portion; so that the first mating portion and the second mating portion form an electrode. Specifically, the first matching portion may be in direct contact with the second matching portion to form an electrode, or may be in indirect contact with the second matching portion to form an electrode through the conductive connecting portion. Moreover, the sum of the resistances of the first matching part and the second matching part changes along with the change of the folding angle, so that the specific folding angle can be obtained through testing the resistance value. Specifically, a plurality of folding angles within the range of the folding angle can be used as sampling values, and after the folding is performed by using the folding angle corresponding to each sampling value, the resistance value of the electrode formed by the first matching part and the second matching part is tested in sequence; finally, a corresponding relation table 1 of the folding angle and the resistance value is obtained. Then, a suitable folding angle can be determined according to the correspondence table 1.
Similarly, in another preferred implementation structure, the first matching portion and the second matching portion are both connected with a voltage, and an insulating layer is arranged between the first matching portion and the second matching portion; so that a capacitor (including a capacitor of 0) is formed between the first mating portion and the second mating portion. Therefore, the capacitance of the first matching part and the capacitance of the second matching part can change along with the change of the turning angle, and therefore, the specific turning angle can be obtained through the test of the capacitance value. Specifically, a plurality of folding angles within the range of the folding angle can be used as sampling values, and after the folding is performed by using the folding angle corresponding to each sampling value, the capacitance value of the capacitor formed by the first matching part and the second matching part is sequentially tested; finally, a corresponding relation table 2 of the turnover angle and the capacitance value is obtained. Then, a suitable folding angle can be determined according to the correspondence table 2.
In addition, the application also provides a method for determining the folding angle of the folding display device, which is similar to the idea of the scheme.
Referring to fig. 5, the method mainly includes:
step 51: acquiring an electrical performance test value formed by the first matching part and the second matching part of the foldable display device in a current folding state;
step 52: according to the electrical property test value, finding out a folding angle matched with the electrical property test value from a preset list, and using the folding angle as the folding angle of the folding display device in the current folding state;
the preset list stores the corresponding relation between the electrical property test value and the folding angle; the electrical property test value is a resistance value or a capacitance value. The preset list may be obtained from empirical values, or may be obtained by establishing a correspondence relationship after accurately testing the fold-down angle and the electrical property test value.
In fact, the user experience can be improved through the determining scheme of the folding angle, the current APP can display the corresponding image picture only by acquiring the folding angle, or the electrical performance test value can be tested reversely, so that the display device is triggered to automatically adjust the folding state according to the found folding angle.
