Disclosed are apparatus and methods of enhancing digital audio signals after compression and decompression. The methods and apparatus include receiving a digital decompressed audio signal, harmonically enhancing the signal, adding warmth to the signal, and combining and frequency equalizing the harmonically enhanced audio signal and the warmth enhanced audio signal to provide a digital enhanced decompressed audio signal. The apparatus is preferably provided in software as instructions to a DSP. Adjustments are included within the software for varying levels of the harmonic enhancing and for varying levels of the frequency equalizing. Methods of distribution are disclosed which include providing the software free with the inclusion in the software of either a one-time use, a partial use, a partially enhanced audio signal use, or non-save adjustments, and selling the software for a price without including the one-time use, the partial use, the partially enhanced audio signal use, or the non-save adjustments.

A liquid crystal display cell having improved cell gap uniformity is made by depositing a plurality of spacer particles on the cell substrate then subjecting the substrate to an external energy source to selectively dislodge and remove the larger particles, such as by immersing the substrate in and ultrasonic bath. Because the larger particles will inherently have a lesser attraction to the substrate relative to their mass, subjecting the entire substrate to the ultrasonic bath will inherently preferentially remove the larger particles, resulting in a distribution having a smaller standard deviation than the initial mixture of particles deposited on the substrate as well as an asymmetric reduction in the number of gap-dominating large particles.

Phosphor and method for the fabrication thereof

A field emission display (,) includes a cathode plate (,) having a plurality of electron emitters (,), an anode plate (,) having a plurality of phosphors (,), and a spacer (,) having a rough surface (,). The roughness of rough surface (,) is selected to improve the charging and discharging characteristics of field emission display (,). Preferably, rough surface (,) is characterized by a peak-to-valley number within a range of 0.5-6 micrometers.

A field emission device (100, 150) includes a cathode plate (102, 180) having electron emitters (116), an anode plate (104, 170) having a phosphor (107, 207, 307, 407) activated by electrons (119) emitted by electron emitters (116), and a vacuum bridge focusing structure (118, 158, 218, 318) for focusing electrons (119) emitted by electron emitters (116). Vacuum bridge focusing structure (118, 158, 218, 318) has landings (121, 122, 221, 322), which are attached to cathode plate (102, 180), and further has bridges (120, 220, 320), which extend above and beyond landings (121, 122, 221, 322, 421) to provide a self-supporting structure that is spaced apart from cathode plate (102, 180).

A field emission display (100) includes a cathode plate (102) having a plurality of electron emitters (124), an anode plate (104) opposing the cathode plate (102), and a bulk-resistive spacer (108) extending between the anode plate (104) and the cathode plate (102). The bulk-resistive spacer (108) is made from an electrically conductive material. The resistivity of the electrically conductive material is selected to remove impinging charges while preventing excessive power loss due to electrical current through the bulk-resistive spacer (108) from the anode plate (104) to the cathode plate (102).
