Brightness and contrast control method for cathode ray tube involves using processor to regulate tube current |
摘要 |
The method involves generating an activation signal for the tube (15). This is generated by a display mode controller (10) and transmitted to a processing unit (13). An operating current for the tube flows through a detector unit (11) and this controls the operating current to be within a defined operating range. Independent claims are included for a control device.
