Abstract: A flat panel display is disclosed which includes a faceplate with a faceplate interior side, and a backplate including a backplate interior side in an opposing relationship to the faceplate interior side. Side walls are positioned between the faceplate and the backplate. The side walls, faceplate and backplate form an enclosed sealed envelope. A plurality of phosphor subpixels are positioned at the faceplate interior side. A plurality of field emitters are positioned at the backplate interior side. The field emitters emit electrons which strike corresponding phosphor subpixels. A plurality of scattering shields surround each phosphor subpixel and define a subpixel volume. The scattering shields reduce the number of scattered electrons exiting from their corresponding subpixel volume. This reduces the number of scattered electrons from charging internal insulating surfaces in the envelope, as well as striking the non-corresponding phosphor subpixels.

Abstract: A present invention field emission display brightness compensation system and method is capable of providing uniform display correction. In onepresent compensation system and method a masking process is utilized thatadjusts the emissions for a particular area. In one exemplary implementation,the relative value of a pixel driver voltage is adjusted to correspond to a basebrightness area. For example, an emitter uniformity area adjustment table is utilized to adjust the voltage value of the emitters. An emitter uniformity areaadjustment table provides a correlation between a pixel location and a brightnesslevel adjustment. The emitter uniformity area adjustment tables are utilized tocreate a software filtering mask that provides compensation for uniformitydifferences between different spots or areas in the display.

Abstract: A method of removing contaminant particles (93) from faceplates (90) in newly fabricated field emission displays so that a uniform distribution of contaminants is achieved at the emitter sites of the display device contaminants are removed from the display faceplate by electron induced desorption. The emission current profile at the emitter sites is selected so that the distribution of reabsorbed contaminants is equalized. The variations in current emission compensate for shadowing effects due to spacer walls (91) to produce a uniform reabsorption distribution. The emitter sites may driven using an aninated contrast image at a constant current for the display.

Abstract: Methods and structures are provided which support spacer walls (100) in a position which facilitates installation of the spacer walls (100) between a faceplate and backplate of a flat display. In one embodiment, spacer feet (111, 112) are formed at the opposing ends of the spacer wall. Tacking electrodes can be provided on the faceplate to assert an electrostatic force on the spacer feet (111, 112), thereby holding the spacer feet in place during installation of the spacer wall. The spacer wall can be mechanically and/or thermally expanded prior to attaching both ends of the spacer wall to the faceplate. The spacer wall is then allowed to contract, thereby introducing tension into the spacer wall which tends to straighten any inherent wavines in the spacer wall. Alternatively, spacer clips can be clamped onto opposing ends of a spacer wall to support the spacer wall during installation. The spacer clips can provide electrical connections to face electrodes located on the spacer wall.

Abstract: A method for creating a faceplate of a display provides a faceplate substrate with a faceplate interior side and a faceplate exterior side. A plurality of barriers are formed on the faceplate interior side, with the barriers defining a plurality of subpixel volumes. Phosphor containing photopolymerizable material mixtures of red, green and blue, are deposited into subpixel volumes, and create a faceplate interior side/phosphor interface. At least a portion of the phosphor containing photopolymerizable material mixture is exposed with sufficient actinic light through the faceplate interior side/phosphor interface to polymerize a selected depth of the phosphor containing photopolymerizable material mixture in the subpixel volumes, and form a polymerized phosphor containing material in a plurality of subpixel volumes. Non-polymerized phosphor containing photopolymerizable material is removed from the polymerized phosphor containing material.
