摘要： Circuits for sequentially addressing memory locations in time with pulses received from a clock are disclosed. The circuits may provide a positive voltage output signal at successive output nodes associated with corresponding stages in the circuit responsive to the application of a clock signal to the circuit stages. The circuit may comprise at least first and second stages wherein said first stage comprises means for providing a positive voltage signal at a first output node in the first stage in response to application of a first positive clock pulse to the first stage, and wherein said second stage comprises means for providing a positive voltage signal at a second output node in the second stage in response to application of a second positive clock pulse to the second stage. Addressing of memory locations that contain pixel information for a video display is one particular application in which sequential addressing may be required. Sequential addressing is useful in video applications because it permits sequential selection of the pixel rows and columns that make up the display screen. Sequential scanning of the memory locations for screen information can be carried out in conjunction with the scanning of an electron source across the screen of the display.

摘要： In order to operate Field Emission Displays (“FEDs”) contain an evacuated space. Generally, two soda-lime glass substrates, separated by a vacuum gap, act as cathode and anode. The vacuum gap is essential for the electrons to be emitted from the sharp cathode tips and travel towards the anode to give up their energy to the phosphor anode plate to emit light. The two plates and the frit seal holding the vacuum gap are under strain due to the atmospheric pressure acting on them. For small size FEDs , this strain is not a problem. However, for large area FEDs, the strain is detrimental both to the glass plates (2 mm thick) and frit seal. Under the strain, both the cathode and anode plates will buckle-in towards vacuum and, in turn, stress the frit seal, causing cracks and vacuum failure. To minimize this effect and enable the FED to operate normally, a field emissive display with a support plate for the cathode plate is disclosed. The support plate may reduce deflection of the cathode plate and decrease stress on the means for sealing the cathode plate to the anode plate. The support plate may be connected to the one side of the cathode plate at multiple points along the cathode plate. The support plate may also include plural channels with rounded inner walls defining spaces between the cathode plate and the support plate. Getter material may be provided in these spaces. To facilitate communication between the getter material in each channel, passages may be provided between the channels in the support plate.
