Abstract: A display system attached to a fixed substrate (12) includes a two dimensional light modulator array (24, 42) having a plurality of light modulators (28, 44) arranged in a first row and a second row, with the first row at a first row position with respect to the fixed substrate and the second row at a second row position with respect to the fixed substrate. A mechanically movable element (14) such as a rotary stepper or piezovibrator attaches the two dimensional light modulator array (24, 42) to the fixed substrate (12). The movable element (14) is operated to move the first row from its first row position to substantially occupy the second row position. In conjunction with various image processing deblurring and rescaling techniques, this effectively distributes light between adjacent rows to compensate for failure of one or more light modulators in a row.

Abstract: In a liquid crystal display device (5,5a,5b,5c,5d) having pixels arranged in a matrix form, light is allowed to pass or blocked depending upon whether or not a voltage is applied to electrodes (2,2a,3) each corresponding to the pixels, and the display (5,5a,5b,5c,5d) operation is conducted by controlling the transmission/nontransmission of light. When a conductor (63,70) or switching element (61) connected to an electrode (2a) is broken, it is not possible to apply such a voltage to the respective electrode (2,2a,3). Such a pixel (7a) is always at the light transmission display state, with the result that the pixel (7a) becomes a bright spot, thereby degrading the display (5,5a,5b,5c,5d)quality. Therefore, a blocking piece (6,6A,6a,6b,6c,46a,46b,46c,46d,46e) for blocking light is disposed over the pixel (7a) which becomes a bright spot. This prevents the bright spot from appearing, thereby improving the display quality.

Abstract: A liquid crystal display device and a method of compensating for a luminance point defect of the liquid crystal display device. After a luminance point pixel is detected, a laser beam (10) is irradiated from an excimer laser oscillator on a portion in the vicinity of a surface of one of glass substrates (2, 27) of a liquid crystal panel (1) on which an illuminating light (40) is incident, the portion being located on the same irradiation path of the illuminating light with the luminance point pixel (5). In this way, the portion (16) is laser-etched, thereby forming a rough surface in the portion. When such a panel is used in a projection device, the light transmitted through the luminance point pixel (5) is scattered and so reduced. Accordingly, the luminance point pixel is inconspicuous against normal pixels (28) around the luminance point pixel (5).

Abstract: An active matrix liquid crystal display panel is composed of a number of liquid crystal display elements arranged in the form a matrix, each of the liquid crystal display elements being composed of an individual display electrode, a common electrode, and a liquid crystal material sandwiched between the individual display electrode and the common electrode. The individual display electrode of each of the liquid crystal display elements is selectively activated through an associated active element. A liquid crystal display element connected to a defective active element is modified to become a half tone display element, so that the liquid crystal display element connected to the defective active element becomes overshadowed or inconspicuous when the display panel is in operation.
