the fliptop display 5 the light source 60 generates light this light is conducted through the lcd housing 50 the conducted light is then projected into the back surface 72 of the lcd module 70 fig5 shows a close up view of the lower portion of fig4 in fig5 the rear portion 54 of the lcd housing 50 has a thickness d 6 the fractional portion of the lcd housing 50 between its outer surface 58 and the light source 60 has a thickness d 7 the light reflective coat 53 and its protective layer 56 add a negligible thickness the light source 60 depicted in fig5 is a cold cathode fluorescent lamp that has a diameter d 3 for maximum light coupling the cold cathode fluorescent lamp 60 may be embedded in the lcd housing 50 so that the aperture 61 of the cold cathode fluorescent lamp 60 is completely adjacent to the lcd housing 50 the lcd module 70 which has a thickness d 8 may be adjacent to the inner surface 52 of the lcd housing 50 thus it can be seen from fig5 that the depth d of the fliptop display 5 closely approximates the sum of the thickness d 7 of the.
