Namely, the display write line LW and display read line LR sometimes cross with each other. In the moving picture display mode, 10 to 15 frames are changed within a second. Since the write operation of picture data and read operation of the relevant data for display on the liquid crystal panel LCD are performed without any relation asynchronouslychange of display screen to the moving picture 2 of FIG.
Therefore, interface between the moving picture 1 and moving picture 2 becomes distinctive as illustrated in FIG. In the display of 60 frames per second, when the 15 frames of moving picture are displayed per second, change of display is required once for every four frames.
The display profile of this figure is also applied to the subsequent figures. Summary of the picture display system is explained here considering, as an example thereof, a liquid crystal display device which is a typical display device and a mobile telephone using the liquid crystal display device as 59152006 fs assignment display section.
The audio interface AUI 2 controls prefetch of an audio input from the microphone 9 and output of an audio signal to the speaker In this case, four changes of display occur in every second and flickers can be observed for times in every second.
In general, a dot matrix type display device is configured with a display panel including a large number of pixels arranged in a two-dimensional matrix and a display control circuit for displaying still pictures and moving pictures by supplying a picture signal to this display panel. A profile of displaying moving pictures within the display area of the still picture is illustrated in the display screen of the mobile telephone of FIG.
As a display device of this type, a liquid crystal display device, an organic EL display device, a plasma display device or a field emission type display device, etc. A display read line by the display operation scanning line: A configuration of the display drive control circuit of the present invention can be summarized as follows.
In the case where a picture is changed in the course of display thereof, change of display is performed while a moving picture 1 and a moving picture 2 exist simultaneously in the same display.
It is therefore an object of the present invention to provide a display drive control system which has realized low power consumption by controlling power consumption of the additionally provided moving picture display function which has eliminated flicker of display and ensures high display quality during display of moving pictures.
The present invention introduces, in order to attain the object described above, an interface corresponding to moving pictures which is referred to as a first function in addition to a system interface in the still picture mode which is referred to as a second function and is characterized in realization of low power consumption by changing to a still picture interface system interface for operation of interface corresponding to moving pictures only during the required period.
Therefore, such interface is not preferable from the viewpoint of display quality. Requirement for display of moving pictures on a display screen of a mobile telephone is increasing in recent years. For the display of moving pictures, it is necessary to write the picture data synchronously with the display operation.
Accordingly, the existing drive control circuit is capable of displaying moving pictures but it is difficult for such circuit to display moving pictures in higher picture quality which can be seen smoothly.
The display data in the display operation is read from the display memory M 63 depending on the display address generated by the display address generation circuit DAG. Such flickers of display has yet been left as a problem to be solved in the display device of this type.
When the write line and read line cross with each other as illustrated in FIG.
When a configuration to eliminate such flicker of display described above is additionally provided to the liquid crystal controller driver, power consumption of a display device increases and this large power consumption is not preferable particularly for a mobile terminals such as a mobile telephone.
This display address is generated in synchronization with the clock generated by the built-in clock generation circuit CLK For the display to the liquid crystal panel 13, picture data is read from the memory 5 and is subject to the necessary processes in the microcomputer MPU Therefore, write operation of picture data and display operation thereof are performed asynchronously.
In this case, a write address is generated in the write address generation circuit SAG 61 with each signal of system interface signal CS chip select and signal RS resister select and signal WR write.
