Abstract: The volume controller of the present invention does not require a use of an expensive main controller and a quartz oscillator to generate the pulse signals for regulating the volume. The volume controller can handle the noise generated by turning of an encoder and regulates the volume accurately despite the noise. As the volume is increased, a first pulse signal generating circuitry generates pulse signals with an already established width according to the pulse signals of the encoder. As the volume is decreased, a second pulse signal generating circuitry generates pulse signals with already established width according to the pulse signals of the encoder. The first or the second pulse signal generating circuitry will act optionally according to the increase or decrease of the volume. When the first or the second pulse generating means are optional and yet generates the pulse signal, the control means will disconnect the standard terminal of the encoder that is not to be grounded.

Abstract: To uniform the liquid crystal particle of the liquid crystal layer of a PDLCD where a liquid crystal is scattered and emulsified with a polymer, the polymer is scattered on a conductive layer of a substrate. The liquid crystal is scattered thereon to be emulsified during a predetermined hour. Thereafter, by the same method as that of forming the polymer layer, the polymer is scattered on the liquid crystal layer to form a second polymer layer thereby obtaining the homogeneous thickness of the liquid crystal layer of the PDLCD.

Abstract: To provide a liquid crystal display having an anti-static electricity structure which can prevent a display error caused by a static electricity generated during manufacturing process and remained on an anti-electrical charge layer, the present invention provides a liquid crystal display system comprising: a pair of panels respectively having common electrodes and segment electrode; an insulating layer formed on each common and segment electrodes; an anti-electric charge layer formed on the insulating layer; a first earth pattern contacting the anti-electrical charge layer and formed at more than one of each common and segment electrode; and a second earth pattern formed at a circuit board and connected with the first earth pattern to earth a static electricity in a liquid crystal.
