The electro optical characteristics of backlight unit (BLU) have a great influence on the characteristics of LCD like uniformity, luminance and chromaticity etc. There are many measurement methods for BLU of electro optical characteristics. It is so different that the measurement method for BLU in each company (e.g., the testing position, test condition, equipment concept etc.). Therefore, this Standard will present the general measurement method.

 

This Standard is applicable to BLU for liquid crystal display (LCD) and the measurement includes only the optical area. The other areas (electric characteristics, reliability, and so forth) are dealt with by other SEMI Standards.
