Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all 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.
Example one
In order to solve the problem in the related art that the electronic paper is limited by the load of the driving integrated circuit IC, which results in difficulty in increasing the resolution, as shown in fig. 1, fig. 1 is a schematic diagram of a basic structure of an electronic paper provided in this embodiment, where the electronic paper includes, but is not limited to:
the display screen 1, the display screen 1 includes N ROWs of data lines ROW;
the display panel comprises at least two drive Integrated Circuits (ICs) which respectively correspond to different data updating time, wherein each drive Integrated Circuit (IC) is respectively connected with a plurality of columns of data lines (ROW) so as to divide the display panel 1 into at least two display areas which correspond to different data updating time.
It should be understood that the driving integrated circuit IC is used for transmitting data voltages to the display panel 1 through the data lines ROW; the electronic paper provided by the embodiment comprises electronic ink in the display screen 1, and the display screen 1 is driven by EDP (electronic data processing), so that the electronic ink only changes color when being electrified, concretely, the display screen 1 comprises a plurality of pixel points, each pixel point consists of single electronic ink, and the electronic ink can be seen as a capsule. Each capsule has liquid charges, wherein the positive charges are white, and the negative charges are black. When positive and negative voltages are applied to one side of the liquid, the liquid with charges can be attracted and repelled respectively, and therefore each pixel point can display white or black; that is, after the display screen 1 of the electronic paper is powered off, the current display picture cannot disappear or be updated, and only when the display screen 1 receives the data voltage for driving transmitted by the data line ROW next time, the display picture of the display screen 1 can disappear or be updated;
it should be understood that the display screen 1 in the electronic paper is a complete electronic screen physically, the electronic paper includes at least two driver ICs, data update times of the at least two driver ICs are different, and each driver IC is connected to a plurality of ROWs of data lines ROW, so that the display screen 1 is logically divided into at least two display areas, and the electronic paper can drive the corresponding display areas to update data (display screen) through the driver ICs; for example, as shown in fig. 2, the electronic paper includes two driving integrated circuits a and B, where the driving integrated circuit a and the driving integrated circuit B correspond to different data update times, respectively, the driving integrated circuit a corresponds to a part of the data lines ROW, and the driving integrated circuit B corresponds to the remaining part of the data lines ROW, so as to divide the display screen 1 into two display areas a and B, and the display areas a and B have different data update times, so that the driving integrated circuit a can control the display area a to update data, so that the display screen of the display area a is updated without causing data update of the display area B, i.e., without affecting the display screen of the display area B; meanwhile, when the B display area is controlled by the B drive integrated circuit IC to update data, the display picture of the B display area is updated, and the display picture of the A display area is not influenced.
Bearing the above example, for another example, the electronic paper includes three driver integrated circuits, i.e., a, B, and C, and divides the display screen 1 into display areas, i.e., a, B, and C, where the a driver integrated circuit IC and the B driver integrated circuit IC respectively correspond to different data update times, and in some examples, the data update time of the C driver integrated circuit IC is different from the data update times of the a and B driver integrated circuits, so as to implement that the display areas a, B, and C have different data update times; in some examples, the data update time of the C driver integrated circuit IC may be the same as that of the a or B driver integrated circuit IC, so that the data update time of the C display area is the same as that of the a or B display area; in addition, the present embodiment does not limit the number of driving integrated circuits IC of the electronic paper, and can be flexibly set by the relevant person.
It can be understood that the multiple columns of data lines ROW corresponding to each driving IC are continuous data lines ROW, for example, two driving ICs a and B are included in the electronic paper, the display screen 1 includes N columns of data lines ROW, and then 1-X columns of data lines ROW correspond to the driving IC a, and X +1-N columns of data lines ROW correspond to the driving IC B. Meanwhile, the number of display areas in the display screen 1 of the electronic paper corresponds to the number of driver ICs, that is, if there are M driver ICs, there are M display areas, where M is a positive integer greater than or equal to 2.
It should be understood that when the display screen 1 is divided into a plurality of display areas, each display area corresponds to a different common voltage, so as to implement independent data update of each display area; specifically, a plurality of common voltages generated in the electronic paper reach the common electrode layer through the TFT routing layer, and thus different common voltages are provided for different display regions, where the present embodiment is not limited to a method of providing different common voltages for each display region, and a method of providing different common voltages for each display region will be described below.
In some examples of this embodiment, the electronic paper further comprises: and each common voltage generation unit corresponds to one display area and is used for providing common voltage for the corresponding display area. The number of the common voltage generating units is equal to that of the display areas, that is, when N display areas exist, N common voltage generating units exist, where N is a positive integer greater than or equal to 2, each common voltage generating unit corresponds to one display area, and different display areas correspond to different common voltage generating units;
taking the above example as an example, the electronic paper includes two driving integrated circuits a and B, and the display panel 1 is divided into two display areas a and B, and then there are two common voltage generating units, one common voltage generating unit is used for generating a common voltage for driving the display area a, and the other common voltage generating unit is used for generating a common voltage for driving the display area B.
In some examples of this embodiment, the electronic paper further comprises: a common voltage generating unit and a selector; the common voltage generating unit is used for generating a common voltage corresponding to each display region, and the selector is used for transmitting the common voltage generated by the common voltage generating unit to the corresponding display region. That is, the number of the common voltage generating units in the display panel 1 is lower than the number of the display regions, and the common voltage generating units generate at least two common voltages, and at this time, the common voltages of different regions are separated by the selector and transmitted to the corresponding display regions.
Taking the above example as an example, for example, the electronic paper includes two drive integrated circuits IC of a, B, divides the display panel 1 into two display areas of a, B, and there is only one common voltage generating unit at this time for generating a common voltage for driving the display areas of a and B, and transmits the common voltage for driving the display area of a to the display area of a through the selector, and transmits the common voltage for driving the display area of B to the display area of B through the selector.
It should be understood that the number of output channels of the driving IC determines the data lines ROW to which the driving IC can be connected, and when the number of output channels of the driving IC is X, the driving IC can be connected to X columns of data lines ROW.
In some examples of this embodiment, when the electronic paper includes at least two of the driving integrated circuits ICs, the number of output channels of the at least two driving integrated circuits ICs is the same, so that the number of the data lines ROW to which the at least two driving integrated circuits ICs are connected is the same. It can be understood that, when M (M is an integer greater than or equal to 2) driver ICs are included in the electronic paper, there are at least two driver ICs whose output channels are the same in number, and at least two driver ICs whose output channels are the same in number have the same number of connected data lines ROW; in some examples, when the number of output channels of each driving integrated circuit IC in the electronic paper is consistent, the number of driving integrated circuits IC is determined by the number of output channels of the driving integrated circuit IC and the number of columns of the data lines ROW;
for example, the electronic paper includes a plurality of driver ICs, each driver IC outputs 180 channels, and when N ROWs of data lines ROW can divide by 180, the electronic paper includes N/180 driver ICs, and the resolution of the display screen 1 in the electronic paper is N; if the N ROWs of data lines ROW cannot divide the data lines ROW by 180, the electronic paper includes [ N/180] +1 driver ICs, that is, if the N ROWs of data lines ROW cannot divide the data lines ROW by 180, N/180 is rounded up to obtain the number of driver ICs. Further, it can be understood that, when the N column data lines ROW of the display screen 1 cannot be divided by 180, the display horizontal direction resolution of the display screen 1 is N.
In some examples of this embodiment, when the electronic paper includes at least two of the driving integrated circuits ICs, the number of output channels of the at least two driving integrated circuits ICs is different, so that the number of the data lines ROW to which the at least two driving integrated circuits ICs are connected is different. It can be understood that, when M (M is an integer equal to or greater than 2) driver ICs are included in the electronic paper, the number of output channels of at least two driver ICs is the same, and the number of data lines ROW to which at least two driver ICs are connected is different.
In some examples of this embodiment, the display panel 1 includes a first display panel 41 and a second display panel 42 that are disposed along a length direction of the data line ROW, where the first display panel 41 includes N/2 columns of the data line ROW, the second display panel 42 includes N/2 columns of the data line ROW, and the first display panel 41 and the second display panel 42 respectively correspond to at least one of the driver ICs. As shown in fig. 3, namely, the column direction is driven in a bidirectional manner, the data line ROW also needs to be separated vertically, so that the resolution in the vertical direction is doubled as compared with the original design, and the resolution is improved, at this time, the common voltages of the first display screen 41 and the second display screen 42 are different, the first display screen 41 includes at least one display area, and the same second display screen 42 includes at least one display area; it should be understood that the number of the display areas included in the first display screen 41 and the second display screen 42 is flexibly set by the relevant personnel, that is, the number of the display areas included in the first display screen 41 and the second display screen 42 may be equal or may not be equal.
In some examples of this embodiment, the electronic paper further comprises: a picture generation unit 2; the picture generating unit 2 is configured to generate data required by each driver IC, and sequentially distribute the data required by each driver IC to each driver IC according to the data update time of each driver IC, so that each driver IC updates a picture displayed in the corresponding display area according to the received image; specifically, the picture generation unit 2 is configured to generate an image to be displayed in each display area of the display screen 1, and sequentially distribute the image to each driver IC according to the data update time of each driver IC, so that each driver IC updates a picture displayed in the corresponding display area according to the received image.
Bearing the above example, wherein the electronic paper further comprises: the adapter 3 is a bridge between the image generating unit 2 and the IC, such as a Flexible Printed Circuit (FPC)/Film Circuit board (Film) device with routing and binding functions. The function is to guide the data of the picture generation unit 2 to each IC, taking FPC as an example, the switching device 3 may be 1pcs FPC, that is, one FPC includes all the traces of ICs, or (n) pcs FPC, that is, one FPC for each IC, or, of course, any number from 1 to n.
The electronic paper provided by the embodiment includes but is not limited to: the display screen comprises N columns of data lines; the display screen comprises at least two drive integrated circuits which correspond to different data updating times respectively, wherein each drive integrated circuit is connected with multiple columns of data lines respectively so as to divide the display screen into at least two display areas which correspond to different data updating times, the electronic paper is divided into the two display areas with different data updating times through the at least two drive integrated circuits in the electronic paper, the load and the power consumption of a single drive integrated circuit are reduced, the data updating times of the drive integrated circuits are different, the independent refreshing of each display area is realized, and the user control experience is improved.
Example two
For better understanding of the present invention, the present embodiment provides a more specific example to illustrate the electronic paper provided by the present invention:
the electronic paper comprises a display screen 1, a plurality of drive Integrated Circuits (ICs), a switching device 3 and a picture generation unit 2, wherein the display screen 1 comprises a plurality of data lines (ROW), each IC can output 180 channels as an example, the resolution in the display horizontal direction is 180n, and n depends on the number of the ICs;
the switching device 3 is a bridge between the image generating unit 2 and the IC, such as a device with routing and bonding functions like FPC/Film. The function is to guide the data of the picture generating unit 2 to each IC, taking FPC as an example, the switching device 3 can be 1pcs FPC, that is, one FPC includes all the IC wiring, or (n) pcs FPC, that is, one FPC for each IC, and certainly, any number of 1-n;
the picture generation unit 2 has two functions, the first is to generate data required by the IC display; secondly, the IC is distributed to a plurality of ICs in sequence according to different time;
the display panel 1 is divided into a plurality of display regions according to the driving integrated circuit IC, and each display region has a single common voltage, that is, VCOM (common electrode) of each display region needs to be divided, so as to ensure that each IC can separately and independently control each corresponding region; specifically, the VCOM voltage generated by an IC or generated on a circuit driving board reaches a common electrode layer through a Thin Film Transistor (TFT) wiring layer; it can be seen that VCOM1 and VCOM (n) are emphasized that in addition to the separation of the transparent electrode (ITO) layers, the VCOM voltage generation unit also needs to be separated, that is, if the driving IC generates a voltage, the driving IC is separated, and this design IC itself is separated; if the circuit driving board generates, it is necessary to separate VCOMs of different regions by a selector, or more simply, different VCOM voltage generating units of different regions; the object is achieved;
in actual operation, the image generating unit 2 generates a pattern (pattern) required for displaying, and then allocates the pattern to each corresponding IC according to different time, where there is only a time difference between the ICs, and there is no certain time sequence, such as 1 → n; or n → 1; or other sequences, the final display effect is not influenced because the power-down display is still and the VCOM is also turned on or off according to the sequence; of course, it is also possible to transmit data for a single IC, such as connecting the FPC for IC1, disconnecting the others, then connecting IC2 \8230;, or connecting the FPCs for ICs 1 and 2 together, then disconnecting them, and the like.
In particular, in order to increase the resolution in the row direction, as shown in fig. 4, the display panel 1 may be divided into a first display panel 41 and a second display panel 42, i.e., column-wise bi-directional driving, such that VCOM requires two regions above and below in layers; and the data line ROW also needs to be separated up and down to prevent the IC1 and the region responsible for ICn from influencing each other; by the design, the resolution in the vertical direction is doubled compared with the original design;
in the above, the resolution ratio can be theoretically infinite, and from the perspective of updating data, the splicing effect on the drive is realized, and the purpose of improving the resolution ratio is achieved.
