  • Touch panel assembly
    Patent number: 7237937
    Abstract: In a touch panel assembly, the thickness of a touch panel is successfully reduced by using a touch panel 10 provided with no reinforcement member. A housing frame 50 that supports the components of a front light unit 20 in an integral manner is provided with a touch panel positioning mechanism, and the touch panel 10 is fixed to the positioning mechanism, whereby the absence of a reinforcement member is duly compensated for, thus ensuring the strength of the touch panel 10. Deformation of the touch panel 10 that occurs when the touch panel 10 is pressed for operation can be attenuated by a transparent buffer member 5 disposed between the touch panel 10 and a light conductor plate 22. Therefore, the touch panel 10 deformed is prohibited from contacting and damaging the light conductor plate 22, thus preventing the light conductor plate 22 from deteriorating in its functional performance.
