    Abstract: PROBLEM TO BE SOLVED: To provide a non-superimposed sampling pulse signal generator which can be applied to an active matrix display device, and to provide a method for generating the signal.
    SOLUTION: The signal generator includes a pulse distributor 30, a guard signal generator 32, and a logic arithmetic circuit 31. The method for generating the signal comprises the steps wherein the pulse distributor 30, responding to the trigger of a start pulse, successively generates and outputs a plurality of pulse signals SR0, SR1 and so on having different phases; the guard signal generator 32 supplies guard signals which carry out switching between a first level and a second level; and the logic arithmetic circuit 31, receiving the pulse signals and guard signals, carries out calculation and successively outputs a plurality of sampling signals ϕ1, ϕ2 and so on, and avoids superposition by providing, based on the time of the second level where the guard signal is located, time difference Td to a sampling area of sampling signals adjacent to each other.

    Abstract: A high reflection and transmission transflective liquid crystal display (TLCD) that requires only a single cell gap. Instead of reducing the cell gap of the R sub-pixel region, the invention reduces the birefringence change Deltan of reflective pixels (R) so that the total retardation change Deltand of R is equal to that of the transmissive pixels (T). This is realized by a partial switching of the pixels of approximately 45 degrees which occurs in the reflective pixel (R) region of the single cell gap by applying fringing fields, generated by a discontinuous electrode, to the molecules in the reflective pixel (R) region of the cell gap.

    Abstract: A device structure for single cell gap reflective and transflective liquid crystal displays (TF-LCDs). For an entirely reflective LCD, the imbedded wire-grid polarizer (WGP) serves as a polarization-dependent for the ambient light. For a transflective TF-LCD, the WGP only covers the reflective pixels. The disclosure also includes a method of using single cell gap liquid crystal displays (LCDs) without phase retardation films by providing a single cell gap LCD having reflective pixels and transmissive pixels, covering solely the reflective pixels, with at least one of: a wire grid polarizer and a broadband cholesteric reflector (BCR), reflecting ambient light off the reflective pixels; and passing back light through the transmissive pixels whereby the cell gap LCD obtains high contrast ratios without using phase retardation films.

    Abstract: Transflective twisted nematic (TN) liquid crystal displays(LCDs) having enhanced transmission efficiencies. Due to the use of circularly polarized light, the novel TN transflective LCD uses a new operation mode between the conventional First and Second Minimums, which alters the retardation value of the reflection and the transmission portions, where the retardation values each include a cell gap spacing. This results in the cell gap spacing in the transmission portion of the transflective LCD to be approximately triple the cell gap spacing in the reflection portion of the transflective LCD whereby the transmission efficiency increases to approximately 90 percent.
