摘要:
There is provided a device for driving a light-emitting display panel in which output limiter element is added to a DC-DC converter which associates a boosting operation. In the drive device, even though a forward voltage of a monitor element increases to operate the limiter element, predetermined display quality can be assured without considerably disrupting a color balance. On a display panel, a display region in which display pixels of R, G, and B are arranged and an arrangement region for monitor elements which monitor forward voltages of R, G, and B are formed. Output voltages obtained by the respective DC-DC converters are controlled based on the forward voltages obtained by the monitor elements. An output limiter is constituted by zener diodes to prevent converter output values from being excessive by increases in forward voltages from the monitor elements due to aging. Limiter values obtained by the zener diodes are set at different levels.

In the drive device, even though a forward voltage of a monitor element increases to operates the limiter means, predetermined display quality can be assured without considerably disrupting a color balance. On a display panel, a display region in which display pixels of R, G, and B are arranged and an arrangement region for monitor elements which monitor forward voltages of R, G, and B are formed.

An output limiter is constituted by zener diodes to prevent converter output values from being excessive by increases in forward voltages from the monitor elements due to aging. Limiter values obtained by the zener diodes are set at different levels. The drive device is designed to prevent a color balance from being considerably disrupted even though a limiter operation is executed due to aging.

An electronic component includes a substrate, a functional element formed on the substrate, a plurality of terminals including a first terminal electrode connected to the functional element and a second terminal electrode layered on the first terminal electrode, and a feed line, one end of which is electrically connected to the first terminal electrode and the other end of which reaches an edge of the substrate, wherein the feed line includes a first portion directly reaching the edge, and a second portion branching from the first portion and then reaching the edge.
摘要:
A nonporous composite material laminate formed by combination of a liquid crystal polymer film with two support membranes and stretching the composite material laminate to provide a multiaxially-oriented liquid crystal polymer film, wherein the liquid crystal polymer film contains 1 to 30 volume percent of a solid particulate material in amounts sufficient to reduce the thickness variability of the film whereby the ratio of the standard deviation of thickness values to the mean thickness value of the film is 0.1 or less. The liquid crystal polymer film has balanced physical properties, uniform thickness, and smooth surfaces. A process for making the composite material and orienting the liquid crystal polymer is also disclosed.

摘要:
Complex-shaped articles formed by gas-pressure-molding composite preforms of liquid crystal polymer and porous polytetrafluoroethylene material are described. Processes for making the composite material preforms and parisons needed for gas-pressure-molding methods, such as vacuum-molding and blow-molding, are also described.

An acoustic wave device includes: a piezoelectric substrate; at least five IDTs (InterDigital Transducers) arranged on the substrate in directions of SAW (Surface Acoustic Wave) propagation; and two balanced terminals connected to two first IDTs that are two out of the at least five IDTs and are 180 degrees out of phase. One of a pair of comb electrodes of one of the two first IDTs is connected to one of the two balanced terminals, and one of a pair of comb electrodes of the other one of the two first IDTs being connected to the other one of the two balanced terminals. The other comb electrodes of the two first IDTs are connected in series, and one of a pair of comb electrodes that form an IDT that is included in the at least five IDTs and is not connected to the two first IDTs is grounded.
摘要:
A method of correcting a magnification of a mask pattern formed on a mask substrate. The method includes applying forces to four pressurizing points of an outer periphery of an approximately ring-shaped frame, which supports the mask substrate and has a rectangular window, on substantially extended lines of two diagonal lines of the rectangular window, and adjusting at least an angle, to the extended lines, of a vector of the forces applied to each of the pressurizing points.
