Color liquid-crystal display apparatus using delta configuration of picture elements

A method of arranging a plurality of color picture elements of a color liquid crystal display device including a plurality of parallel scanning electrodes arranged in a first direction and a plurality of parallel signal electrodes arranged in a second direction, perpendicular to the first direction, to improve image quality and overall display efficiency, comprising the steps of:

• a) forming each of a plurality of picture element groups from the plurality of color picture elements, each color picture element being associated with a kparticular color corresponding to red, green, or blue;
• b) configuring the plurality of color picture elements, for each of the plurality of picture element groups, in a delta configuration;
• c) arranging each of the picture element groups, on the color liquid crystal display device, in the first direction parallel to the scanning electrodes, the color picture elements being disposed in a plurality of lines along the first direction such that color picture elements of the same color in any two adjacent lines are arranged at a 1.5 element pitch in the first direction and color picture elements of the same color in any two alternating lines are arranged in parallel along the second direction;
• d) connecting each of the plurality of parallel signal electrodes to only color picture elements of the same color on alternating sides of each signal electroded in alternating ones of the plurality of lines, respectively, so as to drive only color picture elements of the same color through each signal electrode;
• e) connecting each of the plurality of scanning electrodes to at least two color picture elements of a picture element group parallel thereto.

A color liquid crystal display apparatus, comprising:

• a plurality of picture element groups arranged in a matrix, each picture element group including,
• a plurality of color picture elements, each color picture element associated with a particular color corresponding to red, green, or blue,
• said plurality of color picture elements being arranged in a delta configuration;
• a plurality of scanning electrodes arranged in parallel and extending over said matrix in a first direction;
• and
• a plurality of signal electrodes arranged in parallel and extending over said matrix in a second direction perpendicular to said first direction;
• said picture element groups being arranged parallel to said scanning electrodes and in such a manner that said color picture elements are disposed in a kplurality of lines along said first direction, color picture elements of the same color in any two adjacent lines being arranged at a 1.5 element pitch in said first direction, color picture elements of the same color in any two alternate lines beign arranged in parallel along said second direction,
• each said signal electrode being of a straight line configuration and being connected only to color picture elements of the same color at every two color picture element widths in said second direction, so as to drive only color picture elements of the same color through each signal electrode, and being connected in an arrangement such that color picture elements of picture element groups to be connected at adjacent signal electrodes are different in color, and
• said scanning electrodes being connected to at least two color picture elements of picture element groups parallel thereto.
