The schematic diagram of the display system 100 of one embodiment of the invention it is based on reference to Fig. 1, Fig. 1.Such as figure
Shown in 1, display system 100 comprises time schedule controller 110 and a display floater 120, Qi Zhongxian
Show and comprise at least one source electrode driver by panel 120 (in this embodiment, it is multiple source electrode driver
122_1 to 122_N) and an active display area 124 (active display area 124 the most actively battle array
Row).In this embodiment, time schedule controller 110 is a point-to-point time schedule controller, and sequencing contro
Device 110 is utilized respectively serializer/deserializer interface to transmit image data to source electrode driver 122_1
To 122_N, and display system 100 is a liquid crystal indicator (liquid crystal display, LCD).
In the operation of display system 100, first, time schedule controller 110 should by multiple data transmission rates
Setting for a discrete data transmission rate, then, time schedule controller 110 receives multiple image step by step
(frame) view data, and utilize the plurality of data transmission rate to transmit the (warp of the plurality of image respectively
Processing) view data is to each source electrode driver 122_1 to 122_N, wherein for each shadow
As, for (frame), the view data of its correspondence is come merely with one of them in the plurality of data transmission rate
Transmission.Then, after time schedule controller 110 receives view data, source electrode driver 122_1 is extremely
122_N transmits the data data wire to active display area 124 of correspondence.
In detail, data transmission rate DR1 is utilized with reference to what Fig. 2, Fig. 2 were based on one embodiment of the invention
The schematic diagram of image is transmitted, as in figure 2 it is shown, time schedule controller 110 utilizes data to transmit to DR3
Rate DR1 transmits the view data of the first image F1 to source electrode driver 122_1 to 122_N, and sharp
The view data of the second image F2 is transmitted to source electrode driver 122_1 extremely by data transmission rate DR2
122_N, utilizes data transmission rate DR3 to transmit the view data of the 3rd image F3 to source electrode driver
122_1 to 122_N, utilizes data transmission rate DR2 to transmit the view data of the 4th image F4 to source
Driver 122_1 to 122_N, and be repeatedly with data transmission rate DR1, DR2, DR3,
DR2 be respectively transmitted after image F5, F6, F7, F8 the rest may be inferred, by utilizing different pieces of information
Transfer rate transmits image data, and electromagnetic interference peak value can be sufficiently decreased.
It should be noted that Fig. 2 is only example explanation, it is not intended as the restriction of the present invention.For example,
The quantity of data transmission rate determines according to considering of designer, that is time schedule controller 110 can use two
Individual, four or five different data transmission rates transmit image data；Fig. 2 shows that any two is adjacent
The view data of image be utilized respectively different data transmission rates and transmit, but, in other enforcement
In example, some can utilize same data transmission rate to transmit adjacent to the view data of image, and citing comes
Say, utilize data transmission rate DR1 to transmit image F1 and F2 and F4 and F5, and utilize data
Transfer rate DR2 transmits image F3 and F6；And in other embodiments, data transmission rate is not
Periodically it is used for transmitting the view data of image.Change in these designs all should be under the jurisdiction of the present invention's
Protection domain.
The schematic diagram of the image format of the image 300 of one embodiment of the invention it is based on reference to Fig. 3, Fig. 3.
Image 300 comprises actively view data and non-active data, and this active view data is used for showing to be led
On dynamic viewing area 124, it is " the 3rd region " shown by Fig. 3；Rather than active data does not then show
On active display area 124, i.e. vertical blanking interval (the vertical represented by " the 1st region " of Fig. 3
Blanking interval, VBI) data, and the water represented by " the 2nd region " and " the 4th region " of Fig. 3
Flat blanking interval (horizontal blanking interval, HBI).In this embodiment, vertical when preparing transmission
When blanking interval data are to source electrode driver 122_1 to 122_N, time schedule controller will pass by switch data
Defeated rate.Specifically, when preparing the vertical blanking interval data transmitting image 300 to source electrode driver,
It is inclined to switch an oscillator frequency that one foundation microprocessor in time schedule controller 110 performs firmware code
Move, be used for transmitting the data transmission rate of the view data of image 300 with switching.
In addition, in this embodiment, for being transferred to source electrode driver 122_1 to 122_N
Each image for, the image data amount of image comes with reference to the data transmission rate being used for transmitting this image
Adjusting, the image wherein utilizing higher data transfer rate to transmit has bigger data volume.Come in detail
Say, for each image, by with reference to being used to transmit the data transmission of the view data of this image
Rate, the data volume of non-active data in this image, such as these vertical blanking interval data and/or this level disappear
Hidden issue evidence, can correspondingly be increased or decreased.
Using Fig. 2 as example, it is assumed that the shadow of the view data of each image of input timing controller 110
As size is 2040*1100, time schedule controller 110 will increase by 4 articles of vertical blanking interval data wires to
One image F1, that is the image size of the first image F1 is 2044*1100, and utilize data transmission rate
DR1 transmits the first image F1；Then, time schedule controller 110 will increase by 2 vertical blanking intervals
Data wire is to the second image F2, that is the image size of the second image F2 is 2042*1100, and utilizes
Data transmission rate DR2 transmits the second image F2；Then, time schedule controller 110 will not adjust the 3rd
The data volume of image F3, that is the image size of the 3rd image F3 is 2040*1100, and utilize data
Transfer rate DR3 transmits the 3rd image F3, and the rest may be inferred.
In another example, it is assumed that the image of the view data of each image of input timing controller 110
Size is 2040*1100, and time schedule controller 110 increases horizontal blanking interval data and makes the first image F1
Image size be 2040*1102, and utilize data transmission rate DR1 to transmit the first image F1；Connect
, time schedule controller 110 will not adjust the second image F2, that is the image size of the second image is
2040*1100, and utilize data transmission rate DR2 to transmit the second image F2；Then, time schedule controller
110 minimizing horizontal blanking interval data are so that the image size of the 3rd image F3 is 2040*1098, and profit
The 3rd image F3 is transmitted by data transmission rate DR3.
By the switch data transfer rate when preparing transmission vertical blanking interval data, and adjust hanging down of this image
The data volume of straight blanking interval data, active display area 124 will not have flash-point to occur.
With reference to Fig. 1 to Fig. 4, Fig. 4 be based on one embodiment of the invention from time schedule controller transmission
