In the following description, dimensions (e.g., length, width, thickness, and depth) of elements (e.g., layers, films, substrates, regions, etc.) in the figures are exaggerated in various proportions for the sake of clarity. Accordingly, the following description and illustrations of the embodiments are not limited to the sizes and shapes of elements shown in the drawings, but are intended to cover deviations in sizes, shapes and so forth that result from actual manufacturing processes and/or tolerances. For example, the flat surfaces shown in the figures may have rough and/or non-linear features, while the acute angles shown in the figures may be rounded. Therefore, the elements shown in the drawings are for illustrative purposes only, and are not intended to accurately depict the actual shapes of the elements or to limit the scope of the claims.
Fig. 1 is a flowchart illustrating an image signal input method according to at least one embodiment of the invention, and fig. 2A is a block diagram illustrating a touch electronic device suitable for the image signal input method in fig. 1. Referring to fig. 1 and fig. 2A, the touch electronic device 100 may be a mobile device (mobile device), such as an electronic paper, a mobile phone, a tablet computer, or a notebook computer. The touch electronic device 100 may include a processor 110 and a touch reflective display panel 120, wherein the processor 110 is electrically connected to the touch reflective display panel 120 to control the touch reflective display panel 120.
The touch reflective display panel 120 is a pixel display panel (pixel display panel) and has a plurality of pixels. The touch reflective display panel 120 has a touch function and can sense the position and movement of the object 10 thereon, wherein the object 10 can be a stylus (as shown in fig. 2A) or a finger. In the embodiment shown in fig. 2A, the touch reflective display panel 120 may belong to an out-cell (out-cell) touch display panel, and may include a reflective display panel 121 and a touch panel 122, wherein the processor 110 is electrically connected to the touch panel 122 and the reflective display panel 121, and the touch panel 122 is fixed on the reflective display panel 121. For example, the touch panel 122 may be adhered to the reflective display panel 121.
The touch reflective display panel 120 may include an electrowetting display panel or an electrophoretic display panel. Taking fig. 2A as an example, the reflective display panel 121 included in the touch reflective display panel 120 may be a display device capable of maintaining an image even without power, such as an electrowetting display panel or an electrophoretic display panel.
It should be noted that, in other embodiments, the touch reflective display panel 120 may also belong to an integrated (on-cell) or an embedded (in-cell) touch display panel. That is, the reflective display panel 121 and the touch panel 122 can be integrated into a whole. Therefore, the touch reflective display panel 120 shown in fig. 2A is only for illustration, and the touch reflective display panel 120 is not limited to be an external touch display panel.
In the image signal input method of the present embodiment, step S101 may be executed first to enable the touch electronic device 100 to be in a handwriting mode or a non-handwriting mode. Specifically, the user can enable the processor 110 to generate the first mode command or the second mode command according to the requirement, so as to adjust the operation mode of the touch electronic device 100. When the first mode command is generated, the touch electronic device 100 is in the non-handwriting mode. When the second mode command is generated, the touch electronic device 100 is in the handwriting mode.
Fig. 2B is a schematic top view of the touch electronic device in fig. 2A in a non-handwriting mode. Referring to fig. 1 and fig. 2B, in the embodiment of fig. 2B, the touch electronic device 100 has a switch key 130, which can be a physical key and is used for switching an operation mode of the touch electronic device 100. When the touch electronic device 100 is in the handwriting mode, the user can press the switch key 130 to enable the processor 110 to generate a first mode command, and the touch electronic device 100 switches from the handwriting mode to the non-handwriting mode according to the first mode command.
On the contrary, when the touch electronic device 100 is in the non-handwriting mode, the user can press the switch key 130 to enable the processor 110 to generate the second mode instruction, and the touch electronic device 100 switches from the non-handwriting mode to the handwriting mode according to the second mode instruction. In addition, it should be noted that fig. 2B illustrates the physical switch key 130 as an example, but in other embodiments, the switch key 130 may be replaced by an icon (icon) displayed on the touch reflective display panel 120, so that the first and second mode commands are not limited to be generated by physical keys (e.g., the switch key 130).
After step S101, the touch electronic device 100 can proceed to step S102 to place the touch electronic device 100 in the non-handwriting mode. In step S102, when the touch electronic device 100 is in the non-handwriting mode, a full-screen signal is input to the touch reflective display panel 120 to update all pixels of the touch reflective display panel 120, wherein the full-screen signal can be input to the touch reflective display panel 120 through a Mobile Industry Processor Interface (MIPI).
Taking fig. 2B as an example, the non-handwriting mode may be a reading mode. When the touch electronic device 100 is in the reading mode, the touch reflective display panel 120 not only can display text (not shown), but also can display page turning icons 122R and 122L. At this time, the user can press the page turning icon 122R or 122L to update the image displayed on the touch reflective display panel 120.
Specifically, when the user touches the page turning icon 122R or 122L, the touch reflective display panel 120 generates a page turning command and inputs the page turning command to the processor 110. The processor 110 receives the page-turning instruction and inputs a page-turning signal to the touch reflective display panel 120 according to the page-turning instruction. The page-turning signal belongs to a full-screen signal, and therefore, after receiving the page-turning signal, the touch reflective display panel 120 updates all pixels, so that the touch reflective display panel 120 displays an image of a next page or a previous page of text content.
The electronic touch device 100 in the reading mode also displays the home icon 122H. When the user presses the home icon 122H, the touch-sensitive reflective display panel 120 generates a home command and inputs the home command to the processor 110. The processor 110 receives the home page command and inputs a home page signal to the touch reflective display panel 120 according to the home page command. The home page signal also belongs to the full-frame signal, so that all pixels are updated after the touch reflective display panel 120 receives the home page signal, so that the touch reflective display panel 120 displays the image frame of the home page. In addition, the page turning signal and the home page signal can be input to the touch reflective display panel 120 through the mobile industry processor interface.
Fig. 2C is a schematic top view of the touch electronic device in fig. 2A in a handwriting mode. Referring to fig. 1 and fig. 2C, after step S101, the touch electronic device 100 can also perform step S103 to enable the touch electronic device 100 to be in a handwriting mode. In step S103, when the touch electronic device 100 is in the handwriting mode, the touch reflective display panel 120 senses a moving track T1 of the object 10 on the touch reflective display panel 120. Taking fig. 2C as an example, when the touch-sensing electronic device 100 is in the handwriting mode, the user can write a text on the touch-sensing reflective display panel 120 with the object 10, such as "a" shown in fig. 2C, and the text (i.e., "a" shown in fig. 2C) is substantially a moving track T1 of the object 10 on the touch-sensing reflective display panel 120.
After the step S103, the touch electronic device 100 proceeds to the step S104, and the processor 110 inputs the local frame signal to the touch reflective display panel 120 according to the moving track T1. Specifically, the touch reflective display panel 120 senses the moving trace T1 to generate a corresponding touch signal. The touch reflective display panel 120 inputs the touch signal to the processor 110, and the processor 110 generates a corresponding local frame signal according to the touch signal and inputs the local frame signal to the touch reflective display panel 120.
After receiving the local frame signal, the touch reflective display panel 120 updates a portion of the pixels corresponding to the moving trajectory T1. In detail, according to the local frame signal, the touch reflective display panel 120 updates only the pixels occupied or distributed by the moving track T1, and does not update other pixels not occupied or distributed by the moving track T1. In addition, the local frame signal can be input to the touch reflective display panel 120 through a Universal Serial Bus (USB).
In summary, when the touch electronic device is in the handwriting mode, the touch reflective display panel updates some of the pixels corresponding to the moving track according to the local frame signal, instead of updating all the pixels according to the full frame signal. Therefore, compared with the existing electronic paper with the handwriting function, the touch electronic device of at least one embodiment of the invention can shorten the time for updating the picture in the handwriting mode to help reduce the situation of handwriting delay, thereby displaying the handwriting track of the user in real time and further improving the convenience of the user in operation.
Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
