发明名称 INPUT AND OUTPUT INTEGRATED DISPLAY DEVICE
摘要 <p>PROBLEM TO BE SOLVED: To sharpen the redisplay of a pressurized point by loading plasticized translucent film whose optical refractive index is smaller than that of air on the input face of a digitizer to diffuse unnecessary light to the periphery though pressure at an inputting time is transmitted to a liquid crystal panel to disorder the orientation of liquid crystal. SOLUTION: As a translucent member consisting of the digitizer and an LCD panel is provided with a refractive index larger than that of air, a film for correcting an optical path 15 formed from material with a refractive index smaller than air is fitted in addition. Therefore, in an area in which the orientation of liquid crystal is disordered at a pressurized part, the film for correcting an optical path 15 is curved similarly to an LCD substrate 21 so that light through the film for correcting an optical path 15 with a small refractive index is refracted, diffused and made invisible from the periphery of the pressurized point to the outside of the pressurized part at a bent part. Thus a redisplay point at the pressurized part is made white and sharp only by the extremely small area of a pen tip part to obtain the easy-to-write input panel.</p>
