An instrument eject system includes a device configured to store an instrument at a storage location within the device. A cover is rotationally coupled to a base via hinge. An ejection element is configured to impose an ejecting force on the instrument when the instrument is stored within the device. A retaining element is configured to retain the instrument within the device in a lock position of the retaining element and to release the instrument in a release position of the retaining element.

Instrument eject system

The generation of flicker is prevented when the contrast of a displayed image is changed. The amplitude of the data voltage whose polarity is inverted at a timing synchronized with the display cycle of an image is changed based on the tone and the designed contrast. At the same time, the position (center) of 0 V relative to the amplitude of the data voltage is offset a larger amount as the contrast increases. This corrects a change V in voltage between the electrodes under the influence of the parasitic capacity of a TFT when the TFT is turned off, so that the voltage between the electrodes is also turned off despite the polarity of the data voltage applied to the liquid crystal, even when the designated contrast is relatively high and the amplitude of the data voltage is relatively small, and even when the designated contrast is relatively low and the amplitude of the data voltage is relatively large.

Method and apparatus for driving a liquid crystal display

In a printed circuit board for a liquid crystal display using Tape Automated Bonding (TAB) for making interconnections, flow of molten solder to adjacent input electrodes on the TAB is prevented as well as short-circuiting between electrodes and wire breakage by using an improved TAB structure that avoids applying a concentration of shearing stress to the input electrodes and retards short-circuiting solder flow. This is accomplished by making the width of the slit for the input electrodes uneven. The width of the slit where each of the electrodes crosses over the slit is narrower than elsewhere.
