Each B board is required as a dedicated board, which requires a lot of time and effort in terms of design and manufacturing management. Therefore, there is a problem in that it is difficult to use both the master IC circuit board and the slave IC board. Furthermore, since the number of output terminals to the master IC circuit board and the slave IC circuit S temporary LCD panel is different, the external lead-out terminals of both boards are different, and it is not possible to use both boards for common use. SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide an LCD module mounting structure that allows both boards to be used in common even if the numbers of output terminals on both boards are different.

A master ICI and slave IC 2 for driving the CD panel are mounted on TAB boards 3 and 13. M in the figure indicates that the IC is used as a master, and similarly, S indicates that the IC is used as a slave. The above two ICIs and 2 are electrically connected to the inner lead portions of the TAB substrates 3 and 13 using means such as thermocompression bonding such as inner lead bonding (ILB). From TAB segment output 6,
Connect pulse heat, etc. to the segment input terminal 4 of the LCD.
They are connected using thermocompression bonding means. The common output terminals of the TAB boards 3 and 13 are connected to the common input section 8 of the LCD baffle via a flexible board or the like using external crimping means, forming the display of the dot matrix display lighting section 7.
