摘要:
A driver IC includes a first driver section for supplying driving signals to n output terminals and a second driver section for selectively switching one of m selection terminals (m >/= 3) to a predetermined potential. The first driver section includes a timing control circuit that provides a timing signal for the second driver section to perform the selective switching. The timing control circuit generates the timing signal based on external control signals supplied through a number of signal lines less than m.

On a substrate of a liquid crystal display device, there are arranged pixel electrodes (6) in a matrix-like formation, TFTs (7) connected to the pixel electrodes (6), video lines (5) and scan lines (2) both of which connected the TFTs (7), and a protective film interposed between the video lines (5) and the pixel electrodes (6). On the substrate, two video lines (5) are laid side by side between the pixel electrodes, and grooves (22) are formed in the protective film between the adjacent video lines (5). Video lead-out lines and scan lead-out lines are arranged in a similar manner.

From a latch circuit (12) composed of five stages of latch circuits each storing data signals corresponding to one line, data signals to be fed to a drive circuit (16) to light the corresponding light-emitting sections are selected by a select circuit (15) selects according to correction data, consisting of 9 bits for each light-emitting section, stored in a Y position correction data storage circuit (13). This permits adjustment of the timing with which the individual light-emitting sections are lit and thereby helps achieve printing with satisfactory linearity.

A semiconductor laser device comprising a semiconductor laser element, a lead frame having an element disposing section where elements are disposed, and a resin bonded to the lead frame, wherein the lead frame has a thick portion and a thin portion, the thick portion being formed to extend at least in the direction of the width of the resin to cover a region having a length equal to or greater than this width. Thereby, the thick-walled construction of the lead frame improves heat dissipation and strength. Also, it stabilizes the positioning reference plane and improves the accuracy of attachment. A semiconductor laser device has a semiconductor laser element, a lead frame having an element mount portion on which the semiconductor laser element is mounted, and a resin kept in intimate contact with the lead frame. The lead frame has a thicker portion and a thinner portion, and the thicker portion is so formed as to extend, in the direction of the width of the resin, over a width equal to or greater than the width of the resin. The thicker portion of the lead frame ensures improved heat dissipation and mechanical strength. Stable reference surfaces for positioning ensure improved fitting accuracy.

The display device of this invention has a pixel element electrode (80), a plurality of drain signal lines (61) for supplying the digital image signals (D0 - D2), a plurality of capacitance elements (C0 - C2) with weighed capacitance value corresponding to the digital image signals (D0 - D2), a refresh transistor RT for initializing the voltage of the pixel element electrode (80) to the voltage Vsc, and charge transfer transistors (TT0 - TT2) for supplying the charge accumulated in the capacitance elements (C0 - C2) to the pixel element electrode (80). An image is displayed by supplying the analog image signal corresponding to the digital image signals (D0 - D2) to the pixel element electrode (80). The configuration of the peripheral circuits of the pixel element portion is simplified, leading to the reduction of the framing area of the panel.

The control circuit 11 causes display of messages received through the communication unit 1 in the display unit 14 in list form. A cursor for making elections from the messages displayed in list form has different patterns. The control circuit 11 associates the cursor patterns with message types. In another embodiment, the control circuit 11 groups received messages into new messages not yet reproduced by a user and old messages already reproduced, causes display of the number of the new messages in a predetermined area of the display unit when the new messages are stored in RAM 13, and display of the number of the old messages in said predetermined area when the new messages are not stored in RAM 13.
