In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will be made with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.
For the sake of simplicity, the drawings only schematically show the parts relevant to the present invention, and they do not represent the actual structure as a product. In addition, in order to make the drawings concise and understandable, components having the same structure or function in some of the drawings are only schematically illustrated or only labeled. In this document, "a" means not only "only one of this but also a case of" more than one ".
A first embodiment of the present invention, as shown in fig. 1, is a display method of a scroll display screen, including:
s100, when the scroll type display screen is unfolded or wound, detecting the variable quantity of the unfolding length of the scroll type display screen at the current moment relative to the unfolding length at the previous moment;
s200, judging whether the variable quantity is zero or not; if yes, executing step S100; if not, executing step S300;
and S300, according to the variable quantity, translating the displayed image on the scroll display screen along the unfolding or rolling direction of the scroll display screen.
Specifically, in this embodiment, the scroll display screen can be rolled on a rotating shaft, and the rotating shaft drives the scroll display screen to be unfolded or rolled up when rotating. For example, the roll-to-roll display screen may include a flexible display screen attached to a rollable substrate for supporting the flexible display screen such that the distal end does not sag when the roll-to-roll display screen is unfolded.
When the scroll display screen starts to be unfolded or wound, the unfolding length of the scroll display screen starts to be detected, and when the rotating shaft starts to rotate, the scroll display screen starts to be unfolded or wound. During detection, the detection can be carried out once every preset time interval, the preset time interval can be set according to the actual condition or the rotating speed of the rotating shaft, and then the variable quantity of the unfolding length of the scroll display screen at the current moment relative to the unfolding length detected at the last moment is obtained according to the unfolding length of the scroll display screen detected at each moment.
And after detecting the variable quantity of the unfolding length of the scroll display screen, judging whether the variable quantity is zero, if so, indicating that the scroll display screen is not unfolded or rolled in the time period from the previous moment to the current moment, not processing the change, and continuously detecting the variable quantity of the unfolding length of the scroll display screen. When the variable quantity is not zero, the scroll display screen continues to be unfolded or wound, at the moment, the displayed image is translated on the scroll display screen along the unfolding or winding direction of the scroll display screen according to the detected variable quantity value, so that the rolling state of the image displayed by the scroll display screen relative to the screen is correspondingly adjusted according to the motion state of the scroll display screen, finally, the image displayed by the scroll display screen is a relatively static image relative to an observer, and the scroll display screen has better initial and final observation experience when being unfolded or wound.
Exemplary, the unrolling length L at the beginning of the unrolling of the roll-to-roll display 1 Zero, the unwind length detected at the second time is L 2 And the deployment length detected at the third time is L 3 The amount of change of the developed length at the second time point from the developed length at the initial time point is L 2 -L 1 The amount of change of the developed length at the third time point from the developed length at the second time point is L 3 -L 2 And sequentially continuing to obtain the variation of the unfolding length at the current moment relative to the unfolding length at the previous moment. When the scroll display screen is unfolded, the variation is a positive value, and when the scroll display screen is rolled, the variation is a negative value, that is, when the scroll display screen is unfolded and rolled, the translation directions of the images displayed on the display screen are opposite.
When the variation is not zero, the image displayed on the display screen is translated along the expansion direction of the scroll display screen, so that the image displayed on the scroll display screen is static relative to the user. The image display effect diagram of the rolled display screen of the embodiment when being unfolded is shown in fig. 2, the image display effect diagram of the rolled display screen of the prior art when being unfolded is shown in fig. 3, and as can be seen from fig. 2 and 3, when the rolled display screen of the prior art is unfolded, the image displayed on the screen is a dynamic moving image relative to the observer, and when the rolled display screen of the embodiment is unfolded, the image displayed on the screen is a relatively static image relative to the observer, which can provide better use experience for the user.
A second embodiment of the present invention is based on the first embodiment, and as shown in fig. 4, when the scroll display screen is unwound or wound in step S100 in the first embodiment, the detecting a variation of the unwound length of the scroll display screen at the current time with respect to the unwound length at the previous time specifically includes:
s110, when the scroll display screen is unfolded or wound, detecting the pixel point coordinates of the unfolded part of the terminal of the scroll display screen at intervals of preset time;
s120, determining the variable quantity of the unfolding length of the scroll type display screen at the current moment relative to the unfolding length at the previous moment according to the pixel point coordinates at the current moment and the pixel point coordinates at the previous moment.
Specifically, the unrolled portion of the roll display screen includes a head end and a terminal end, the head end is a starting end of the roll display screen, and the terminal end may be a junction between a portion of the roll display screen extending out of the electronic device housing and the housing. The joint comprises a row of pixel points, if the transverse direction is an X axis and the longitudinal direction is a Y axis, the X axis coordinate values of the row of pixel points at the joint are the same, the X axis direction is the unfolding direction of the scroll display screen, namely the coordinate value of the terminal of the unfolding part on the X axis is the unfolding length of the scroll display screen, therefore, the coordinate value of any pixel point at the joint can be obtained, and the pixel point coordinate of the unfolded part can be the coordinate value of any one or more pixel points at the joint. The end of the unwound part may also be the intersection of the unwound part of the roll-to-roll display screen and the unwound part (the part still wound on the shaft).
When the scroll display screen is unfolded or wound, the unfolded length of the scroll display screen at each moment can be obtained by detecting the pixel point coordinates of the terminal of the unfolded part of the scroll display screen, and then the variable quantity of the unfolded length of the scroll display screen at the current moment relative to the unfolded length at the previous moment is obtained according to the unfolded length at the current moment and the unfolded length at the previous moment.
A third embodiment of the present invention is based on the second embodiment, as shown in fig. 5, after the step S300 translates the displayed image on the scroll display screen along the extending or retracting direction of the scroll display screen according to the variation, further comprising:
s410, judging whether the scroll type display screen is completely unfolded or completely rolled according to the pixel point coordinates at the current moment; if not, executing step S110; if yes, go to step S420;
s420 ends the flow.
Specifically, if it is assumed that the scroll display screen is unfolded and the horizontal direction is the X axis, if the coordinate value of the X axis of the pixel point of the terminal of the unfolded part is equal to the maximum stroke value of the scroll display screen when the scroll display screen is unfolded, it is determined that the scroll display screen is completely unfolded. If the terminal pixel of the unfolded part is equal to zero but the coordinate value of the X axis is equal to zero, the scroll display screen is completely rolled.
When the scroll display screen is in the fully-unfolded or fully-rolled state, the whole process is ended, and when the scroll display screen is not fully unfolded or fully-rolled, the step S110 is continuously executed, namely, the pixel point coordinates of the unfolded part of the terminal of the scroll display screen at the next moment are continuously detected, then, the variable quantity of the unfolded length of the scroll display screen at the next moment relative to the unfolded length at the current moment is determined according to the pixel point coordinates at the next moment, the displayed image is translated on the scroll display screen according to the variable quantity, and finally, whether the scroll display screen is in the fully-unfolded or fully-rolled state is judged according to the pixel point coordinates of the unfolded part of the terminal at the next moment, if so, the process is ended, and if not, the steps S100 to S410 are continuously executed until the scroll display screen is in the fully-unfolded or fully-rolled state.
