The invention relates to an LCD basal array and a driving method thereof. The basal array includes a substrate basal array, sub-pixel electrodes, datawires and scanning lines, which are in the same row. The sub-pixel electrodes in the same row are connected with one datawire and each datawire is connected with two rows of the sub-pixel electrodes. The sub-pixel electrodes in the same line are separately connected with the two scanning lines alternately in pairs and the sub-pixel electrodes connected with the same scanning line are positioned in the same line. Two sub-pixel electrodes in the same line between the two contiguous datawires are connected with the same scanning line and separately connected with the two datawires. The driving method includes the following steps of: inputting video data signals and sequentially driving the sub-pixel electrodes alternately connected with the two scanning lines in pairs via the two scanning lines when driving each row of the sub-pix electrodes. The invention uses the technical proposal that the two rows of sub-pixel electrodes share one datawire, thus greatly reducing the consumption of the required datawires and the data driving chips and the whole cost of the LCD device.

An edge detecting circuit detects whether a particular pixel belongs to an edge by determining whether the differential value of the pixel from the neighboring pixel is equal to or greater than a threshold. Based on the detection result, an emphasis converter stops OS drive when the image of a pixel area is regarded as an edge image in accordance with the detected result of the edge detecting circuit and implements OS drive when the image of a pixel area is not regarded as an edge image. In this way, the edge detecting circuit detects edge portions of the input video, whereby OS drive in the emphasis converter can be controlled so as to be turned on and off.

A head-mounted image display device with a good operability and a data processing apparatus including such a display device. A head-mounted image display device wherein a liquid crystal panel and an enlarging optical system are crystal display panel through the enlarging optical system housed in a frame and wherein images generated on the liquid are visible in the field of view in front of the frame comprises a first direction detection means (107) disposed in part of the frame (101) for detecting the direction of the user's head; an observation point detection means (109) disposed in part of the frame for detecting the user's line of sight; a trigger input means (4) for transmitting trigger signals; and an image generation means (3, 105) for controlling images generated on the liquid crystal display panel based on signals from the first direction detection, observation point detection, and trigger input means.
