fig. 1 is a block diagram of a driving process of the present invention.
Detailed Description
The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.
Example one
The invention provides a technical scheme that: a dynamic refresh display driving method includes the steps of:
collecting picture information of a front frame and a rear frame, wherein the picture information comprises a whole frame picture and line picture information;
judging a refreshing condition met by the picture information of the previous frame and the picture information of the next frame;
and controlling the refreshing treatment of the subsequent frame according to the judgment result.
Through the steps, it is not difficult to find that when a display is used for displaying animation or processing documents, in order to judge the relevance of the previous and next frames, a display memory is needed to be adopted for storing and comparing the same pixel information of the previous and next frames, and in order to reduce the refreshing of each pixel in the subsequent continuous similar frames, the previous and next frames of the animation or the processed documents are judged and analyzed by the whole frame picture and the line picture, and the refreshing control of the subsequent frames is further realized according to the refreshing conditions met by the judgment results and the refreshing processing mode corresponding to the refreshing conditions, so that the regulation and control of the frame refreshing rate are realized.
In order to perform refresh processing of display data for different association degrees of previous and subsequent frames, the determination information includes: the information of the display pictures of the front frame and the rear frame is the same, the display pictures of the front frame and the rear frame are different and the pictures of the front frame and the rear frame are the same, and the display pictures of the front frame and the rear frame are not completely the same and the pictures of the front frame and the rear frame are different.
In order to realize processing when the front and rear frames display the whole frame picture and the front and rear frame line pictures are the same, the processing of the front and rear frame display picture information is the same comprises the following steps:
and after the first frame picture, giving up refreshing the subsequent frame, and adding a judgment bit for controlling the frame scanning action in the Tcon control design.
In this embodiment, the frame scanning action is controlled by adding the judgment bit in the Tcon control design, thereby reducing the frame refresh rate.
It is necessary to supplement that, through the design of the Tcon circuit and the change of the row and column driving circuits, the refresh frequency of the display frame, row and point is dynamically reduced, thereby reducing the display power consumption and prolonging the service life of the device.
In order to realize the filtering refreshing processing in the display process of the front frame and the rear frame, the processing that the whole frame pictures of the front frame and the rear frame are different and the front frame and the rear frame line pictures are the same comprises the following steps:
skipping the line pictures which do not need to be updated by the encoder, and scanning the line pictures which need to be updated by each frame.
In this embodiment, it is added that the encoder is preferably obtained by modifying a shift register, and a conventional line scanning circuit (gate driver) adopts the principle of a fixed frequency shift register, and scanning is performed in a regular sequence such as progressive or interlaced, but considering the correlation degree of the previous and next frames, a part of line data does not need to be updated, and the shift register needs to be modified into the encoder so as to skip the lines which do not need to be updated, thereby realizing that each frame only scans the lines which need to be updated, and thus reducing the line refresh rate.
In order to realize the processing under the condition that the whole frame and the line picture frame are displayed differently, the processing that the whole frame picture displayed by the front frame and the back frame is not completely the same and the line pictures of the front frame and the back frame are different comprises the following steps:
columns that do not need to be updated are held in a high impedance state by the decoder and loaded by the latch.
In this embodiment, it should be noted that the decoder is preferably an improvement added to an original latch, and a conventional column data signal (source driver) uses a latch to lock all column data in a row at the same time, and selects a row for loading according to row scanning; however, considering the relevance of the previous frame and the next frame, part of the column data does not need to be updated, a decoder needs to be added into the original latch, so that the columns which do not need to be updated keep a high-impedance state, and the columns which need to be updated are loaded through the latch, thereby reducing the point refresh rate.
According to the above, the present invention further provides a specific implementation process of the dynamic refresh display driving method, wherein the LVDS image data input signals (input signals include RGB data signals, clock signals, and control signals) (or other image data input signals) sent from the digital board are processed by a 101-TCON unit (logic board), converted into LVDS signals capable of driving the display screen, and then directly sent to the LVDS receiving chip of the display screen; the image data signals are stored by processing the shift register, the clock signals are converted into control signals which can be identified by the display screen, and the MOSFET tubes in the row-column signal control screen work to control the torsion degree of liquid crystal molecules or the OLED/LED pixels to emit light; driving the display screen to display images, as shown in fig. 1:
102-gate unit: the array units are turned on in sequence by row.
103-source unit: and converting the corresponding display data of each row into voltage, and charging and discharging the storage capacitor of each pixel where the 102-gate unit in the array unit opens the row to the voltage of the corresponding gray scale.
104-array unit: an array of pixels is displayed.
