Title: Lawrence E Smith: Innovator in Video Display Circuitry
Introduction:
Lawrence E Smith, an accomplished inventor hailing from Indianapolis, IN (US), has made significant contributions to the field of video display circuitry. With a strong portfolio of 18 patents, Smith's expertise lies in developing innovative solutions to correct geometric errors in video raster displays. This article delves into his latest patents, career highlights, notable collaborations, and the impact of his inventions.
Latest Patents:
Smith's recent patents include the vertical deflection circuit with raster correction and the horizontal deflection circuit with raster correction. These inventions address the common issue of electron beam sloping during horizontal deflection, resulting in geometric errors like orthogonality and parallelogram errors in raster displays.
The vertical deflection circuit with raster correction utilizes a raster correction circuit to offset the downward slope of the electron beam. By modulating a vertical deflection current with an induced horizontal-rate raster correction current, this circuit significantly eliminates orthogonality and parallelogram errors in the raster.
Similarly, the horizontal deflection circuit with raster correction tackles these geometric errors by modulating a horizontal deflection current at a vertical scanning rate. The phase relationship between the raster correction current and the horizontal-rate deflection current facilitates specific scan line shifts in the upper and lower halves of the raster, effectively correcting the errors.
