Abstract
All display devices require more wider, higher resolution and precision owing to advanced display technology. As the display pannels become wider, BLU also become wider and brighter. The upper glass of the BLU must achieve the constant of its shape and thickness and have uniform brightness. These deformity cause the display quality to make less. Thus high performance of the BLU shape's height and thickness measurement is inevitable. The high speed and precision measurement system will be proposed. To minimize the measurement error we can achieve the desirous results by 2 dividing intervals with different moving velocity on measuring.
