In one embodiment, a touch screen assembly includes a sealing glass comprising ion-exchange strengthened glass having a first coefficient of thermal expansion CTE1. The assembly may also include a backplane glass comprising ion-exchangeable glass having a device surface, an underside and a second coefficient of thermal expansion CTE2, wherein CTE2 is within +/-15.0×10-7/° C. of CTE1. The device surface of the backplane glass is bonded and hermetically sealed to the underside of the sealing glass with a frit seal which encloses a device area between the underside of the sealing glass and the device surface of the backplane glass. An array of metal oxide thin film transistors may be deposited on the device surface of the backplane glass in the device area, wherein the array of metal oxide thin film transistors have a third coefficient of thermal expansion CTE3 that is within +/-15.0×10-7/° C. of CTE1.
