Abrégé
(EN) The invention relates to a driving control method and device and a display device, and belongs to the field of panel driving control. The method can be applied to a controller. The method comprises the steps of adding at least one configuration instruction to a target area of first data in a current data frame to obtain target row data, wherein the target area comprises at least one of an idle area and a data packet; wherein the current data frame comprises multiple lines of data, each line of data comprises to-be-executed data of multiple driving chips, the first data is one line of data in the multiple lines of data, the at least one configuration instruction corresponds to at least one target to-be-executed data, and the target to-be-executed data is located in at least one line of data, starting from the first data, of the current data frame; and respectively sending target row data to the plurality of driving chips, wherein the target row data is used for the plurality of drivingchips to execute a corresponding configuration instruction on the at least one target to-be-executed data. According to the invention, the problem of low sending flexibility of the configuration instruction can be solved. The invention is used for driving control of the display device.
(ZH) 本发明是关于一种驱动控制方法、装置及显示装置,属于面板驱动控制领域。该方法可以应用于控制器,包括:在当前数据帧中第一数据的目标区域中添加至少一个配置指令,以得到目标行数据,目标区域包括空闲区域和数据包中的至少一处,当前数据帧包括多行数据,每行数据包括多个驱动芯片的待执行数据,第一数据为多行数据中的一行数据,至少一个配置指令与至少一个目标待执行数据对应,目标待执行数据位于当前数据帧从第一数据开始的至少一行数据中;向多个驱动芯片分别发送目标行数据,目标行数据用于供多个驱动芯片对至少一个目标待执行数据执行对应的配置指令。本发明能够解决配置指令的发送灵活性较低的问题。本发明用于显示装置的驱动控制。
