By setting the brightness and contrast of a Neso color display to 20%,50%,80% and 100% respectively(totally 16 groups),the black point luminance,white point luminance,tune reproductive curve(TRC),channel additivity,color gamut and the constant channel chromaticity under each setting were measured and compared in detail.

This thesis takes the typical fault of Samsung763 and Samsung765 series color displays as examples to set up fault tree.

By analyzing the principle of typical color VGA monitor circuit, this paper introduced the development of a color monitor maintenance experimental platform, anatomised some key circuits and showed several methods of solving common monitors failure.

S-compensation circuit of multi-frequency color monitor is introduced, and the characteristics and applications of new special IC WT8045 are proposed.

Objective To study the quality assurance(QA) and quality control(QC) of PACS image display device in the department of radiology equipped with PACS and radiology information system (RIS).

At present,the color graph display of FAS has many defects,so a method of identifying and summing fire control block before it has been exploded is proposed.
