Optically transparent polymeric actuator and display apparatus employing same

A display apparatus, comprising:

• a plate member;
• and
• an actuator assembly coupled to the plate member, the actuator assembly including a number of optically transparent liquid crystalline polymer layers, wherein each of the optically transparent liquid crystalline polymer layers is structured to move from a first state to a second state in response to a first stimulus being applied to the optically transparent liquid crystalline polymer layer, wherein the actuator assembly comprises an actuator array coupled to the plate member, the actuator assembly including a number of optically transparent actuators, wherein the number of optically transparent liquid crystalline polymer layers is a plurality of optically transparent liquid crystalline polymer layers, wherein each optically transparent actuator includes an optically transparent bi-stable member including a respective one of the optically transparent liquid crystalline polymer layers, wherein the bi-stable member is structured to move from a first state to a second state in response to a first stimulus and from the second state to the first state in response to a second stimulus, wherein the bi-stable member has arch-shaped portion, wherein the first state is a first arched state and the second state is a second arched state, and wherein the movement from the first state to the second state and the movement from the second state to the first date is each by snap-through action so as to provide haptic feedback.
