摘要： A driving method for a display device that includes: plural read signal lines; plural selectors connected to the read signal lines; plural gate signal lines; a photo-sensor connected to one of the read signal lines based on whether the one of the gate signal lines are switched on; and a detection circuit that detects an output value of the photo-sensor and selectively establishes connections with the read signal lines based on whether the selectors are switched on, includes: switching on one of the selectors; switching on the one of the gate signal lines; and detecting the output value. A timing of switching on the one of the gate signal lines is delayed by a specific period from a timing of switching on the one of the selectors. An influence of switching noises to the detection of the output value remains during the specific period.

摘要： A thin flat-surface type display device having a transmissive display panel is provided, which is capable of securing a space of an essential electric circuit for driving the display device without deteriorating an optical performance (luminance and uniformity thereof) of a surface light source device of an edge light system employed as a backlight. A light guide plate forming the surface light source device of the edge light system has a flat light emitting surface, and a back surface arranged so as to include (1) an inclined flat surface portion where a thickness of the light guide plate decreases linearly from a light-incident portion on which light emitted from a linear light source is incident toward a light-anti-incident portion, and (2) a parallel flat surface portion which is parallel with the light emitting surface in the vicinity of the light-anti-incident portion. Also, the two adjacent surfaces are connected to each other at an interface portion with an interface curved surface such that makes the two adjacent surfaces tangential. In addition, reflection dots are formed at the back surface side of the light guide plate in a predetermined shape at a predetermined density.

摘要： The present invention provides a display device capable of reducing cost by reduction in number of integrators. Signal lines (91 to 94, 95 to 98, 99 to 912, 913 to 916) are brought together into one line by means of signal lines (10a, 10b, 10c, 10d) to be connected to integrators (4a, 4b, 4c, 4d), respectively. Selector lines (71 to 74) orthogonal to the signal lines (91 to 916) are formed and connected to a selector driving circuit (3). An a-SiTFT (12) is formed at each of intersections: an intersection of the selector line (71) and the signal lines (91, 95, 99, 913); an intersection of the selector line (72) and the signal lines (92, 96, 910, 914); an intersection of the selector line (73) and the signal lines (93, 97, 911, 915); and an intersection of the selector line (74) and the signal lines (94, 98, 912, 916). The selector lines (71 to 74) are driven in sequence by the selector driving circuit (3) in the frame period.

摘要： A prism member is interposed between an LED board and a light incidence surface of a light guide plate. The prism member includes a prism sheet consisting of minute prisms that are arranged along the LED board and that have a function of refracting light that is emitted from each LED and thereby inputting, to the light incidence surface, refracted light that is scattered to both sides in the longitudinal direction of the light incidence surface. As a result, chrominance or luminance unevenness can be prevented even if the distance between the LED board and the light incidence surface is short.
