This application claims the priority benefit of China application serial no. 201710905873.0, filed on Sep. 29, 2017. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.
The invention relates to a displaying method, particularly a sequential displaying method.
As technology advanced, all kinds of displaying techniques have been continuously researched on and commodified into display devices of all sizes, such as electro-phoretic displays (EPD), liquid crystal displays, etc. Display devices usually employ digital numbers or hands to display time information, such that users are able to quickly learn the current time. However, take electro-phoretic displays for example, the time required for updating images is relatively long and the electro-phoretic displays thus cannot be used to display image information at higher changing frequency. For example, images for displaying a second hand or the number information on second require changes per second. If electro-phoretic displays are employed to display such information, problems of poor readability due to persistence of vision would be raised.
A sequential displaying method is provided in the invention, the sequential displaying method is a displaying method that is able to improve time displaying.
The sequential displaying method of the invention includes providing a display device. The display device includes a first display area. The first display area has N first sub-areas that are arranged in sequence. N is a positive integer. The sequential displaying method also includes sequentially updating displayed images in the N first sub-areas, wherein a time interval of updating the displayed images in two adjacent first sub-areas of the N first sub-areas is 60/N seconds and a frequency for updating the displayed image in each of the N first sub-areas is once every 60 seconds.
In an embodiment of the invention, N may be 60.

In an embodiment of the invention, a method of updating a displayed image in each of the N first sub-areas includes changing a first image to a second image. One of the first image and the second image is a black image, and the other of the first image and the second image is a white image.
Based on the above, in the sequential displaying method provided in the embodiments of the invention, the display device includes a first display area having N first sub-areas that are arranged in sequence and sequentially updating displayed images in the N first sub-areas with the following method: a time interval of updating the displayed images in two adjacent first sub-areas of the N first sub-areas is 60/N seconds and a frequency for updating the displayed image in each of the N first sub-areas is once every 60 seconds, such that a problem of poor readability when displaying the information on second may be solved.
To make the aforementioned and other features and advantages of the invention more comprehensible, several embodiments accompanied with drawings are described in detail as follows.
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of the specification. The drawings illustrate exemplary embodiments of the invention and, together with the description, serve to explain the principles of the invention.
Exemplary embodiments of the invention are explicitly provided below and explanations thereon are provided in drawings. Whenever it is applicable, identical or similar reference numbers are used to represent identical or similar components in drawings and descriptions and embodiments may be combined with one another. Identical or similar concepts or process are not repeated in some embodiments.
In the specification, ordinal numbers such as first, second, etc. are used to describe all kinds of areas or images, so as to distinguish one area or image from another.
In the embodiment, a frequency for updating a displayed image in each of the N first sub-areas 102A is once every 60 seconds and a time interval of updating displayed images in two adjacent first sub-areas of the N first sub-areas is 60/N seconds. N is a positive integer. When N is 60, the first display area 102 may be used to display information on second. At this time, a time interval of updating displayed images in two adjacent first sub-areas 102A of the N first sub-areas 102A is 1 second but is not limited thereto. N may also be another proper number based on actual needs. A time interval of updating the displayed images in two adjacent first sub-areas 102A of the N first sub-areas 102A is shorter than 60/N seconds. Users may recognize, evaluate or calculate time with use of the display device 100. For example, when users observe displayed images in five consecutive first sub-areas 102A of the N first sub-areas 102A being sequentially updated, 5*(60/N) seconds have passed. In addition, users may also use an image of the first display area 102 to determine the current time.
Specifically, when the first display area 102 is divided into 60 first sub-areas 102A, N may be defined as 60 and a first sub-area 102A of the 60 first sub-areas 102A on the left-most side to a first sub-area 102A of the 60 first sub-areas 102A on the right-most side may sequentially represent the first second to the sixtieth second. After a displayed image in a first first sub-area 102A on the left-most side is updated from a first image to a second image in the first second, the first first sub-area 102A continues to display the second image for 60 seconds. In the second second (one second after the first first sub-area 102A is updated), a displayed image in a second first sub-area 102A is updated from a first image to a second image and the second first sub-area 102A continues to display the second image for 60 seconds. Displayed images in rest of the first sub-areas 102A are updated in the same manner. Hence, in the sixtieth second, the displayed images in sixty first sub-areas 102A have all been updated from the first image to the second image. Users are able to determine the current second by observing an ordinal number of the first sub-area 102A displaying the second image.
Then, in the sixty-first second, a displayed image in the first first sub-area 102A is updated from a second image to a first image and the first image is continuously displayed for 60 seconds. In the sixty-second second (i.e. one second after the first first sub-area 102A is updated), a displayed image in the second first sub-area 102A is updated from a second image to a first image and the first image is continuously displayed for 60 seconds. Displayed images in rest of the first sub-areas 102A are all updated in the same manner. In this way, the displayed image in each of the first sub-areas 102A is updated every 60 seconds. Users are able to determine the current second by observing an ordinal number of the first sub-area 102A displaying the first image. With such displaying method, a displayed image in each of the first sub-areas 102A of the display device 100 does not need to be updated every second and information on second may still be presented for users to correctly determine the current time (second). Moreover, users are able to sense the lapse of time (e.g. seconds) through the plurality of first sub-areas 102A sequentially being updated.
In addition, the display device 100 may further include other display areas, such as a second display area 108. The first display area 102 is disposed in a neighboring area of the second display area 108. More detailed, the first display area 102 may be disposed on at least one side of the second display area 108. In the embodiment, the first display area 102 is, for example, disposed on an upper side of the second display area 108. A displaying method of the display device 100 may further include displaying at least one of information on time, information on date, and information on day of a week in the second display area 108. Taking
The second display area 404 may be disposed on an inner side of the first display area 102 shaped as an enclosed ring. A center of the path shaped as a ring of the first display area 102 overlaps with a center of the path shaped as a ring of the second display area 404, but the first display area 102 and the second display area 404 do not overlap with each other. The second display area 404 has M second sub-areas 404A. M is a factor of 60 or 60. The M second sub-areas 404A may be arranged along another path shaped as an enclosed ring. A shape of the path shaped as an enclosed ring is, for example, a circle but is not limited thereto. A shape of the path shaped as an enclosed ring may also be other shapes. In the embodiment, the sequential displaying method may further include sequentially updating displayed images in the M second sub-areas 404A in a clockwise direction.
A method of updating the displayed image in each of the M second sub-areas 404A and a method of updating the displayed image in each of the N first sub-areas 102A are substantially the same. A major difference therebetween lies in: in the method of updating the displayed image in each of the M second sub-areas 404A, a time interval of updating displayed images in two adjacent second sub-areas 404A of the M second sub-areas is 60/M minutes. For example, the second display area 404 may be configured to display information on minute. As a result, M may be defined as 60, such that a time interval of updating displayed images in two adjacent second sub-areas 404A of the M second sub-areas 404A is one minute but is not limited thereto. M may also be other proper number based on actual needs.
When M is defined as 60 and a chosen second sub-area 404A of the M second sub-areas 404A serves as a starting point, the sequential displaying method may include updating a displayed image in a first second sub-area 404A of the M second sub-areas 404A from a first image to a second image in the first minute. In the second minute (i.e. one minute after the first second sub-area 404A is updated), a displayed image in a second second sub-area 404A of the M second sub-areas 404A is updated from a first image to a second image. Displayed images in rest of the second sub-areas 404A are updated in the same manner. Users are able to learn information on minute through the second sub-areas 404A being sequentially updated. Such displaying method differs from displaying time (e.g. minute) with digital numbers or a hand and offers another representation of time.
In addition, in the embodiment, the third display area 406 has L third sub-areas 406A. L is a factor of 12 or 12. The L third sub-areas 406A may be sequentially arranged along yet another path shaped as an enclosed ring. A shape of the path shaped as an enclosed ring is, for example, a circle but is not limited thereto. A shape of the path shaped as an enclosed ring may also be other shapes. The third display area 406 may be disposed on an inner side of the second display area 404 shaped as an enclosed ring. A center of the path shaped as a ring of the second display area 404 overlaps with a center of the path shaped as a ring of the third display area 406, but the first display area 102, the second display area 404, and the third display area 406 do not overlap with one another. In the embodiment, the second display area 404 is disposed between the first display area 102 and the third display area 406 but is not limited thereto. In other embodiments, the third display area 406 may be disposed in other locations.
The sequential displaying method of the fourth display device 400 may further include sequentially updating displayed images in the L third sub-areas 406A in a clockwise direction. A method of updating the displayed image in each of the L third sub-areas 406A and a method of updating the displayed image in each of the N first sub-areas 102A are substantially the same. A major difference therebetween lies in: in the method of updating the displayed image in each of the L third sub-areas 406A, a time interval of updating displayed images in two adjacent third sub-areas 406A of the L third sub-areas is 12/L hour. For example, the third display area 406 may be used to display information on hour. L may be defined as 12, such that a time interval of updating displayed images in two adjacent third sub-areas 406A of the L third sub-areas 406A is one hour but is not limited thereto. L may be other numbers based on actual needs.
When L is defined as 12 and a chosen third sub-area 406A of the L third sub-areas 406A serves as a starting point, the sequential displaying method may include updating a displayed image in a first third sub-area 406A of the L third sub-areas 406A from a first image to a second image in the first hour. In the second hour (one hour after the first third sub-area 406A is updated), a displayed image in a second third sub-area 406A of the L third sub-areas 406A is updated from a first image to a second image. Displayed images in rest of the L third sub-areas 406A are updated in the same manner. Users are able to learn the information on hour through the L third sub-areas 406A being sequentially updated. Such displaying method differs from displaying time (e.g. hour) with digital numbers or a hand and offers another representation of time. In addition, the fourth display area 408 of the display device 400 may be disposed on an inner side or an outer side of the third display area 406 shaped as an enclosed ring. The first display area 102, the second display area 404, the third display area 406, and the fourth display area 408 do not overlap with one another.
The display device 400 of
In conclusion of the above, the display device provided in the sequential displaying method of the invention includes the first display area having N first sub-areas that are arranged in sequence and sequentially updating displayed images in the N first sub-areas with the following method: a time interval of updating displayed images in two adjacent first sub-areas of the N first sub-areas is 60/N and a frequency for updating each of the first sub-areas of the N first sub-areas is once every 60 seconds. As a result, problems of poor readability due to persistence of vision in prior art may be avoided when applying the sequential displaying method of the invention in electro-phoretic displays to display information on second.
It will be apparent to those skilled in the art that various modifications and variations can be made to the disclosed embodiments without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the invention covers modifications and variations provided that they fall within the scope of the following claims and their equivalents.
