Title:
表示用コントローラドライバと表示部の駆動方法
Document Type and Number:
Japanese Patent JP4106771
Kind Code:
B2
Abstract:
A controller driver for a fluorescent display unit for use in a display system is connected to a host micom which controls operations of the display system and to a display unit. The controller driver comprises an interface, a decoder, a display RAM, an electrode driver, a controller and a clock generator. The interface transfers data from/to the host micom. The decoder identifies and divides the data received from the interface into command data and display data. The display data includes anode data and grid data and the electrode driver includes therein an anode driver and a grid driver. The display RAM stores the display data received from the decoder. The electrode driver actuates the display unit by using the command data and the display data. The controller sets a driving mode and a display mode by using the command data, retrieves the display data and provides the display data to the electrode driver. The clock generator provides timing signals for the interface, the decoder, the anode driver, the grid driver, the display RAM and the controller to coordinate operation timings thereof. The anode data and the grid data are provided to the anode driver and the grid driver, respectively, according to a predetermined timing address.
