Abstract: MODULAR TYPE GUIDED BEAM FLAT DISPLAY DEVICE An evacuated envelope has a rectangular display section and a gun section at one edge of the display section. The display section includes front and back walls which are generally rectangular, in closely spaced, parallel relation, and a plurality of spaced, parallel support walls between the front and back walls forming a plurality of parallel channels. The gun section extends across one end of the channels and includes therein gun structure which will direct electrons into the channels. In each of the channels is a beam guide which confines the electrons in a beam and guides the beam along the length of the channel. The beam guide also includes means for selectively deflecting the electron beam out of the guide at selective points along the guide so that the beam will impinge upon a phosphor screen along the inner surface of the front wall. In each of the channels is a scanning deflector which deflects the path of the beam as it passes from the guide to the phosphor screen so that each of the beams will scan a portion of the phosphor screen. The beams in each channel are scanned transversely across its portion of the screen in a transverse direction opposite to that of the beams in the adjacent channels.

Abstract: The brightness signal for an image display device is digitally processed using an analog to digital converter to translate the signal into digital words. A primary shift register is connected to the output of the analog to digital converter. The primary shift register has a stage capable of containing a digital brightness word for each element in the display line of the device. The primary shift register has a plurality of parallel outputs being spaced X number of stages from each other. Each output is connected to a separate secondary shift register which has X stages.

Abstract: DIGITAL MEMORY ADDRESSING SYSTEM A digital memory may be addressed with an analog signal utilizing a circuit comprising a digital to analog converter. A comparator compares the output of the digital to analog converter to the analog address signal. The output of the comparator is coupled to means for incrementing and decrementing a digital number in response to that output. The digital number incrementing and decrementing means has an output which is coupled to the addressing input of the digital memory. Switch means alternately connects the input of the digital to analog converter to either the output of the random access memory or the output of the means for changing the digital number.

Abstract: An electron gun is controlled by a system which stores the characteristics of the gun in a random access memory. The contents of the memory feed an electron gun driver which properly biases the gun. The characteristics of the gun are stored in the memory by using a collector to sense the electron beam. A comparator is connected to the collector and a reference brightness signal generator. The output of the comparator controls the storage of the characteristics in the memory.
