EMITTING LIGHT METHOD OF CPT

摘要

The inclination angle of a light source varies according to the curvature variation of the inner surface of a pannel to improve the linearity of the Brown tube. The method comprises: (A) differentiating the data related to the inner curvature of the pannel to obtain the data related to the distances from a light source (7) and each position of the pannel (1) through Y-axis; (B) sampling the data by the period (t) of exposing time; and (C) driving cam axis to vary the inclination angle of the light source.
