For example, when the display screen is used as a watch dial, the display area of the watch dial is designed to be the actual display area. In the production process of some products (one of which is a display screen) requiring accurate alignment of all components, due to various process accuracies and equipment deviations, deviation occurs in component alignment, namely the deviation problem; for example, in some watch products, a display screen is used for a dial, and a pointer is a physical pointer, so that the problem that the pointer is offset from the center of the dial (display screen) often occurs; in the existing design, when the offset distance is large (namely, it is determined that user experience is affected), because no appropriate method is available for correction, the offset sample faces rework processing or is determined as a bad sample to be scrapped, which not only wastes resources, but also directly affects production yield and increases loss.
Therefore, it is an urgent need to provide a display device and a display method thereof that can solve the misalignment problem caused by the process, etc., and has simple design, strong feasibility and high product yield.

Based on the same inventive concept, the invention also provides a display method of the display device, the display device adopts the display method, and the display method at least comprises the following steps: a first display stage, a judgment stage and a second display stage; in the first display stage, the first display area is used for displaying a plurality of first scales surrounding the pointer; in the judging stage, deviation distance monitoring is carried out through detection equipment, wherein the deviation distance comprises a first deviation distance Lx between the pointer and the first scale along a first direction; setting an offset bad distance m according to production requirements, wherein the value of m is greater than or equal to the width of one sub-pixel along the first direction; when Lx is less than m, the display device continues to keep the display work of the first display stage; when Lx is larger than or equal to m, the display device enters a second display stage; in the second display stage, the first display area and the second display area jointly display a plurality of second scales surrounding the pointer, and the distance between the pointer and the second scales along the first direction is Lx ', wherein Lx' is more than or equal to 0 and less than m.
Compared with the prior art, the display device and the display method thereof provided by the invention at least realize the following beneficial effects:
the display device of the invention adds a first sub-display area and a second sub-display area which at least comprise a column of sub-pixel columns on two opposite sides of a first display area in a first direction as a display deviation adjusting zone in the first direction, and the display deviation adjusting zone does not need to be displayed or is displayed according to an actual background when a sample is good; when the pointer and the scales displayed by the display panel deviate for a defective sample, the display deviation adjustment zone performs deviation display according to the deviation distance, optionally, if the pointer deviates towards the left side in the first direction relative to the scales displayed by the display panel, the first sub-display area on the left side of the first display area and the first display area are started to display the second scales together, and if the pointer deviates towards the right side in the first direction relative to the scales displayed by the display panel, the second sub-display area on the right side of the first display area and the first display area are started to display the second scales together, so that the first sub-display area and the second sub-display area do not need to start display work at the same time, and the power consumption of the display device is saved. After the deviation adjustment is finished, the relative position of the pointer and the scale displayed by the display panel is unchanged, so that the deviation can be normally displayed on the visual effect even if the deviation occurs, the reworking treatment of a deviation sample or scrapping of a bad sample is avoided, the loss and the cost are reduced, the better user experience degree can be achieved, the practicability is high, and the production yield is improved.

Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise.

the identification structure 20 comprises at least one pointer 201.
Specifically, the display device 000 of the present embodiment may be an article (one of which is the display panel 10) including components that need to be precisely aligned, for example, the display device 000 may be a watch dial, an industrial dashboard, an automobile dashboard, or other devices having an identification structure (e.g., a physical pointer). For example, in some watch products, the dial uses the display panel 10 for displaying the clock scales, and the identification structure 20 is a physical pointer, so that the problems that the component alignment deviation occurs and the pointer and the center of the dial (the display panel 10) deviate due to various process precision and equipment deviation often occur; in the existing design, when the offset distance is large (namely, it is determined that user experience is influenced), because no appropriate method is available for correction, the offset sample is subjected to rework treatment or is determined as a bad sample to be scrapped, so that resources are wasted, the production yield is directly influenced, and loss is increased. More specifically, some devices having an identification structure (e.g., a physical pointer) such as the watch dial, the industrial dashboard, and the automobile dashboard may be formed by punching a hole in the middle of the display panel, and the pointer is fixed on the surface of the display panel by a fixing member penetrating through a through hole of the display panel, for example, the fixing member is a screw fixed to a chassis structure of the display device, and the chassis structure is provided with a nut fixed to the screw.
Therefore, the display device 000 provided in this embodiment includes the display panel 10 and the identification structure 20 that are oppositely disposed, the optional identification structure 20 is a strip-shaped structure, the identification structure 20 includes at least one pointer 201, for example, when the display device 000 is a watch and clock product, the pointer 201 may be any one or more of an hour hand, a minute hand or a second hand, when the display device 000 is a product such as an industrial instrument panel, an automobile instrument panel, and the like, the pointer 201 may be a recognizable pointer, the identification structure 20 is located on the light emitting surface side of the display panel 10, so that a scale may be displayed on the display panel 10 below the identification structure 20, and the identification structure 20 is used for pointing to the scale above.
As shown in fig. 2, fig. 2 is a schematic plane structure diagram of the display panel 10 in the normal display state in fig. 1, when the display device 000 of the present embodiment is a watch and clock, when the display panel 10 is in operation, a portion of the display area AA is used for displaying a plurality of scales 30 surrounding the pointer 201, and specifically, the sub-pixels 101 corresponding to the positions on the panel where the plurality of scales are displayed may be in a display state, and the sub-pixels 101 at the rest positions may be in a state of not displaying or displaying other background colors different from the colors of the scales. Fig. 2 only schematically illustrates the number of the displayed surrounding scales 30 and the number of the pointers 201, and in implementation, the number of the displayed scales 30 and the number of the pointers 201 may be designed according to the requirements of customers, and this embodiment is not particularly limited.
Moreover, the display area AA of this embodiment at least includes a first display area AA1 and a second display area AA2 arranged around the first display area AA1, and when the display device 000 is manufactured and aligned and debugged, the display device may include a first display stage, a judgment stage, and may further include a second display stage;
referring to fig. 2, fig. 3-fig. 5, fig. 3 is another schematic plan view of the display device of fig. 1 at a first display stage, fig. 4 is a schematic plan view of the display device of fig. 1 at a second display stage, fig. 5 is another schematic plan view of the display device of fig. 1 at the second display stage, after the display device 000 is manufactured, the display device firstly enters the first display stage, and at this time, the first display area AA1 is used for displaying a plurality of first scales 31 surrounding the pointer 201; at this time, the first display area AA1 is in a display state, and only the sub-pixels 101 in the area corresponding to the first scale 31 in the range of the first display area AA1 are in the display state (in fig. 2-5, the scale display position is the display state of the sub-pixels 101, and the interval between the sub-pixels 101 in fig. 1 is recognizable by human eyes, but in actual implementation, the size of each sub-pixel 101 is small, so the interval between the sub-pixels 101 is not recognizable by human eyes, and when a scale is displayed by a plurality of sub-pixels 101 together, the sub-pixels 101 in the rest positions are recognizable by human eyes as a whole scale as shown in fig. 2-5), and the sub-pixels 101 in the rest positions may be displayed or not displayed (the sub-pixels 101 except the scale position in the figure are not shown), and the second display area AA2 may be displayed or not displayed, and in specific implementation, the setting may be selected according to the actual situation.
Then, entering a determination stage, performing offset distance monitoring by using an external detection device, where the offset distance includes a first offset distance Lx between the pointer 201 and the first scale 31 along the first direction X (the offset distances in this embodiment all indicate vertical distances from a center point of the pointer to a center point of the scale in a certain direction, and then the first offset distance Lx is specifically a vertical distance from a center point of the pointer 201 to a center point of the first scale 31 along the first direction X), where as shown in fig. 2, when the first offset distance Lx is substantially 0 or smaller (Lx < m, and a value of m along the first direction X is greater than or equal to a width of one subpixel 101), it indicates that the pointer 201 of the display device 000 and the first scale 31 displayed by the display panel 10 in the first display stage do not offset, and the alignment work precision of a previous process reaches a standard, and at this time, the display device 000 continues to maintain the display work in the first display stage, and does not need to enter a second display stage, and the display device 000 continues to flow out as a good product that does not offset to a next process.
When the first deviation distance Lx is greater than or equal to m as shown in fig. 3, it means that the pointer 201 of the display device 000 and the first scale 31 displayed in the first display area AA1 are seriously deviated, and need to be adjusted;
specifically, as shown in fig. 4 and 5 (the first scale 31 is shown by a dotted line and the second scale 32 is shown by a solid line in fig. 4 and 5), the display device 000 enters a second display stage, in which both the first display area AA1 and the second display area AA2 are in a display state, and display adjustment is performed according to a value of the first deviation distance Lx, the first display area AA1 and the second display area AA2 jointly display a plurality of second scales 32 surrounding the pointer 201, and in the second display stage, the distance between the pointer 201 and the second scale 32 along the first direction X is Lx ', where 0 ≦ Lx' < m, i.e., after the display is adjusted, the distance Lx 'between the pointer 201 and the second scale 32 along the first direction X is within the range m, and the idealized Lx' is 0 (as shown in fig. 5), and in this time, the pointer 201 and the second scale 32 are not deviated.
The display device 000 of this embodiment includes the display panel 10 and the identification structure 20 that are disposed opposite to each other, the optional identification structure 20 is a long bar structure, the identification structure 20 includes at least one pointer 201, the display area AA includes a first display area AA1 and a second display area AA2 disposed around the first display area AA1, only the first display area AA1 is in a working state under the condition that scales displayed by the identification structure 20 and the first display area AA1 do not deviate, and when deviation adjustment is needed, the second display area AA2 enters the working state, which is beneficial to saving power consumption of the display device 000. Along the first direction X, the plurality of sub-pixels 101 form a plurality of sub-pixel columns 101L; along the first direction X, the first sub-display area AA21 and the second sub-display area AA22 located at two opposite sides of the first display area AA1 respectively include at least one row of sub-pixel rows 101L, that is, the widths of the first sub-display area AA21 and the second sub-display area AA22 in the first direction X are at least the width of one sub-pixel 101 in the first direction X, so that when the mark structure 20 and the first scale 31 displayed only in the first display area AA1 are deviated, the display and non-display of at least one sub-pixel 101 are adjusted to make the distance between the second scale 32 and the original first scale 31 have one sub-pixel 101 in the first direction X, thereby achieving the purpose of adjusting the deviation. If the widths of the first sub-display area AA21 and the second sub-display area AA22 in the first direction X are both smaller than the width of one sub-pixel 101 in the first direction X, even if the deviation adjustment is required, the first sub-display area AA21 and the second sub-display area AA22 of the second display area AA2 enter a display working state, the distance between the finally displayed second scale 32 and the original first scale 31 is not greater than the width of one sub-pixel 101 in the first direction X, and the deviation adjustment is meaningless, so that the purpose of adjusting the deviation between the mark structure and the display scale cannot be achieved.
Therefore, in this embodiment, the first sub-display area AA21 and the second sub-display area AA22 at least including one column of the sub-pixel rows 101L are added at two opposite sides of the first display area AA1 in the first direction X to serve as a display deviation adjustment zone in the first direction X, and the display deviation adjustment zone does not need to be displayed or is displayed according to an actual background when the sample is good; when the sample is an inferior product, the pointer and the scale displayed by the display panel are deviated, the deviation display is performed in the deviation adjustment zone according to the deviation distance, optionally, if the pointer deviates to the left side in the first direction X relative to the scale displayed by the display panel, the first sub-display area AA21 on the left side of the first display area AA1 and the first display area AA1 are started to display the second scale 32 together, and if the pointer deviates to the right side in the first direction X relative to the scale displayed by the display panel, the second sub-display area AA22 on the right side of the first display area AA1 and the first display area AA1 are started to display the second scale 32 together, so that the first sub-display area AA21 and the second sub-display area AA22 may not need to start the display operation at the same time, which is favorable for further saving the power consumption of the display device 000. This embodiment makes the scale relative position that pointer and display panel show unchangeable after accomplishing the deviation adjustment, from this, even take place the deviation and also can normally show on visual effect, avoid the deviation sample to do over again to handle or be judged as bad sample and scrap, be favorable to reducing the loss and practice thrift the cost, can also reach better user experience degree, and the feasibility of implementing is strong, helps improving the production yield.
It should be noted that fig. 2 to fig. 4 of this embodiment explain the technical solutions only by using the display device 000 as an implementation of a watch, and by using a distance between a position of one pointer 201 in the 12-point direction and a scale representing 12 points at the top of the surrounding scale in the first direction X as a reference, as a basis for determining whether the alignment is deviated or not, in a specific implementation, other pointers in the mark structure 20 and other scales displayed on the display panel 10 may also be used, which is not described in detail in this embodiment. In the manufacturing of the display area AA of the display panel 10 of the present embodiment, each sub-pixel 101 may be manufactured together, that is, the specifications of the sub-pixels 10 in the first display area AA1 and the second display area AA2 are the same, and only the positions are different. Fig. 1 to 4 of the present embodiment illustrate the technical solution of the present embodiment by using the display device 000 as a square, it can be understood that the display device 000 of the present embodiment may also be in other shapes such as a circle, and the display device 000 in other shapes can still achieve the effect of the present embodiment, which is not described herein again, and can be understood by referring to the description of the square display device 000.

If the widths of the third sub-display area AA23 and the fourth sub-display area AA24 in the second direction Y are both smaller than the width of one sub-pixel 101 in the second direction Y, even if the deviation adjustment is required, the third sub-display area AA23 and the fourth sub-display area AA24 of the second display area AA2 enter the display working state, the distance between the finally displayed second scale 32 and the original first scale 31 is not greater than the width of one sub-pixel 101 in the second direction Y, and the deviation adjustment is meaningless, so that the purpose of adjusting the deviation between the mark structure and the display scale is not achieved.

The embodiment makes the relative position of the pointer and the scale displayed by the display panel unchanged after the deviation adjustment is completed, so that the deviation can be normally displayed in a visual effect even if the deviation occurs, the deviation sample is prevented from being reworked or judged to be scrapped, the loss is reduced, the cost is saved, better user experience can be achieved, the practicability is high, and the production yield is improved.
