Abstract: A system for rendering point primitives for output to an electronic display includes electronics configured to determine a position of a point primitive within a sub-pixel grid. The electronics configured to determine a size of the point primitive and to determine a positional relationship between a pixel and the sub-pixel grid. The system includes a storage circuit configured to determine a first sample bit mask based on the size and based on the position of the point primitive. The system includes at least one set of selector circuits configured to select a second sample bit mask the size of the pixel based on the first sample bit mask and based on the positional relationship between the pixel and the sub-pixel grid. The second sample bit mask indicates which sub-pixels are to be illuminated on the electronic display to represent the point primitive.

Abstract: Apparatus and method are provided for using a multi-element field emission cathode in a color cathode ray tube. The field emission cathode may have from four to ten field emission arrays linearly arranged. The arrays are preferably formed from carbon-based material. An electron gun assembly focuses electron beams from each array on to a phosphor stripe or dot on the screen of the cathode ray tube. Deflection apparatus moves the beam from each field emission array according to clock signals. Clock signals also turn on or turn off voltage to contacts controlling electron current from the array. Values of voltage applied, determined by a video signal, determine the intensity of electron current from each array, which controls the intensity of the light emitted by each color stripe or dot of phosphor on the phosphor screen.

Abstract: A cathode ray tube (CRT) device is disclosed that increases image resolution. The CRT device includes a plurality of electron guns to produce a plurality of electron beams. A plurality of separate phosphor dots corresponding to separate colors are produced when impacted by the electron beams. The CRT device also includes steering electronics to guide the electron beams to the plurality of separate phosphor dots that form part of separate and shifted color planes.

Abstract: A charged particle beam system uses multiple electron columns to increase throughput. One or more multiple electron emitters are in one or more vacuum sealable gun chambers to allow the gun chamber to be replaced with electrons guns having emitters that have been previously conditioned so that the system does not need to be out of service to condition the newly installed emitters.

Abstract: A cathode ray tube video display comprises a cathode ray tube (CRT) for displaying a video signal (Vin) coupled thereto. A cathode ray tube electron beam blanker (201) is coupled to the cathode ray tube (CRT) and is responsive to a blanking trigger signal (GK) for blanking an electron beam (e) within the cathode ray tube (CRT). A blanking controller (200) is coupled to the cathode ray tube electron beam blanker (201) and generates the blanking trigger signal (Gk) for controlling electron beam blanking, wherein the electron beam (e) is blanked for different durations in accordance with one of a hot and cold start condition.

Abstract: A cathode ray tube device in which two deflection yokes and two electron guns are used, but in which only one shadow mask is used. Image uniformity is obtained by creating a partial overlap of the two images created by the two yokes.
