Micropearl for LCD spacing is a true sphere made of fine plastic particles which are resistant to neat, cold, and chemicals. It has been used worldwide for many years, and in conjunction with LCD makers, has played an important role in the development of LCDs.Three grades (SP, SPN, SPS) are available.
Grades
Standard Type
Micropearl SP
(*CV = 5 to 6%)
High Precision Type
Micropearl EX
( CV = 3% or less)
Application(Function)
·Discoloration prevention of under cell gap
·Higher precision of the cell of LC
* CV is an index to indicate the accuracy of particle diameter.
(CV = Standard Deviation / Average Particle Diameter)
Characteristics
Inexact particle size distribution can lead to abnormalities in the cell gap, which leads to partial uneven coloration across the display.
Micropearl SP, SPN and SPS have very sharp particle size distribution.
Various precision, color and surface treatment is available on clients' requirements.
