数据显示控制系统用来控制若干刷新存储器中有关数据的显示,刷新存储器在多种显示器中,包括在图象选择显示器、图象叠加显示器和图象位移显示器中都是很实用的。刷新存储器中的每个数据包含一显示控制位,这些位可确定是否在显示屏上显示数据。数据显示控制系统从各刷新存储器读出一数据信息以作图象显示,并仅在此数据信息中的一显示控制位的内容显示在显示器上时,该系统才包含将此数据信息转换成图象显示器的一个视频信号。对每个数据来说,显示控制位的内容是可变的。
The data display control system is used to control the display of relevant data in a number of refresh memories which are useful in a variety of displays, including image selection displays, image overlay displays and image displacement displays. Each data in the flash memory contains a display control bit that determines if the data is displayed on the display. The data display control system reads a data message from each of the flash memories for image display and only when the content of a display control bit in the data message is displayed on the display includes the conversion of the data message to a map A video signal like a monitor. For each data, the contents of the display control bits are variable.
