Liquid crystal driver I for driving CD panel and LCD panel
C and a precision part in which the peripheral circuit portion is connected by a heat seal connector. In the LCD panel, a transparent electrode such as ITO was formed on glass, a liquid crystal material was sealed between two upper and lower glasses through a spacer, and a polarizing plate and a reflecting plate were attached to the surface of the glass. Electronic components. LCD
Since the module is required to be miniaturized, the outer shape of the LCD panel is also miniaturized. However, on the one hand LC
In order to ensure the reliability of the D module, it is necessary to secure a certain width for the crimping portion between the heat seal connector and the LCD panel. When connecting the heat seal to the LCD panel, apply a heated crimping tool as shown in Fig. 2 to about 50kg / c.
pressurized with m 2. The heat seal is a circuit in which a circuit is printed on a base film of several tens of μm, and an LCD panel is subjected to a very large stress. Further, as shown in FIG. 3, in the conventional LCD panel, the polarizing plate and the reflecting plate did not exist up to the end of the glass. For this reason, the LCD panel terminal portion is very fragile, and the possibility of occurrence of breakage such as chipping is very high.
