▁on ▁the ▁right ▁of ▁the ▁diagram . ▁Here , ▁light ▁L 2 ▁can ▁pass ▁through ▁polar izer ▁A . ▁ ▁In ▁practice , ▁other ▁schemes ▁of ▁implementation ▁exist ▁with ▁a ▁different ▁structure ▁of ▁the ▁L C ▁mole cules ▁for ▁example ▁without ▁any ▁tw ist ▁in ▁the ▁O FF ▁state . ▁As ▁both ▁electro des ▁are ▁on ▁the ▁same ▁substr ate , ▁they ▁take ▁more ▁space ▁than ▁T N ▁matrix ▁electro des . ▁This ▁also ▁reduces ▁contrast ▁and ▁bright ness . ▁ ▁Super - IP S ▁was ▁later ▁introduced ▁with ▁better ▁response ▁times ▁and ▁colour ▁reprodu ction . ▁ ▁Adv antages ▁▁ ▁IP S ▁pan els ▁display ▁consistent , ▁accurate ▁color ▁from ▁all ▁view ing ▁angles . ▁A ▁state - of - the - art ▁( 2 0 1 4 ) ▁comparison ▁of ▁IP S ▁vs . ▁T N ▁pan els ▁concerning ▁colour ▁consist ency ▁under ▁different ▁view ing ▁angles ▁can ▁be ▁seen ▁on ▁the ▁website ▁of ▁Japan ▁Display ▁Inc . ▁ ▁Un like ▁T N ▁L CD s , ▁IP S ▁pan els ▁do ▁not ▁light en ▁or ▁show ▁tail ing ▁when ▁touched . ▁This ▁is ▁important ▁for ▁touch - screen ▁devices , ▁such ▁as ▁smart ph ones ▁and ▁table ts . ▁ ▁IP S ▁pan els ▁offer ▁clear ▁images ▁and ▁stable ▁response ▁time . ▁ ▁Dis adv antages ▁▁ ▁IP S ▁pan els ▁require ▁up ▁to ▁ 1 5 % ▁more ▁power ▁than ▁T N ▁pan els . ▁ ▁IP S ▁pan els ▁are ▁more ▁expensive ▁to ▁produce ▁than ▁T N ▁pan
