摘要： PROBLEM TO BE SOLVED: To eliminate obstruction of lateral stripes arising from polar inversion by a line inversion drive system by making the polarity of display data to be supplied to display elements differ at every adjacent dot at least in a part of the same line, at every line period, and at every field period (or at every frame period).
SOLUTION: For example, an left upper end picture element is driven to sequentially repeat the inversion like +, -, +, - with a field period from the 1st field. And, a voltage waveform polarity of the picture elements adjacent to the one to which attention is paid is controlled so as to be inverted with respect to the latter. In each field, the voltage waveform polarity is inverted every line. Thus, by dot inversion drive, voltage of different polarities is impressed on adjacent picture elements in each line, and the polarities are averaged between the adjacent picture elements, and as a result, such a display averaged in the line becomes possible and the obstruction of lateral stripes is eliminated.

摘要翻译：要解决的问题：为了消除由线路反转驱动系统极地反转产生的横向条纹的阻碍，使得至少在同一行的一部分中，每个相邻点提供显示元件的显示数据的极性不同，在每个行期间，以及每个场周期（或每个帧周期）。解决方案：例如，左上图像元素被驱动以用+， - ，+， - 依次重复反演，其中第一场的场周期。并且，控制与注意事项相邻的图像元素的电压波形极性相对于后者反转。在每个场中，电压波形极性每行反转。因此，通过点反转驱动，对各行的相邻像素施加不同极性的电压，并且相邻像素之间的极性被平均化，结果，在线中平均化的显示成为可能，并且阻塞横向条纹被消除。

摘要： PROBLEM TO BE SOLVED: To provide an adjusting method for reducing flickers generated at a frame cycle in a liquid crystal display device or the like, and to provide a display device therefor. SOLUTION: When liquid crystal panels 10 corresponding to the colors R, G, B are actively driven by an X-shift register 11 (R, G, B) and a Y-shift register 12 (R, G, B), AC-driving is carried out so that the polarity of a write signal to the G-color liquid crystal panel 10G is inverted to that of write signals to R- and B-color liquid crystal panels 10R, 10B, and also a Vcom voltage of each liquid crystal panel is adjusted to reduce flickers. Moreover, for example, the Vcom voltage supplied to the B-color liquid crystal panel 10B is finely adjusted so as to reduce flickers of a synthesized picture of each liquid crystal panel. The shift registers 13 (R, G, B) are for pre-charging, and display signals can also be written by line-inversion or dot-inversion driving.

摘要： PROBLEM TO BE SOLVED: To reduce deviation between channels of a driving device of an LCD for sampling plural bits simultaneously. SOLUTION: Video signals which are made parallel by S/H(sampling and holding) circuits 34 and 35 have inter-channel deviation of DC offset components corrected by output circuits 39 and 40. Namely, the output circuit 39 extracts the DC offset component from a signal S2 by a resistance 47 and a capacitor 48, a compactor 50 compares it with the output voltage of a reference voltage 49, and after an error signal is integrated by an integrator 51, an operational amplifier 54 corrects the DC offset component. Further, a comparator 41 detects an error of a signal S3 on the basis of the signal S2 as to an amplitude component and it is outputted to an integrator 43 in specific timing through a switch 42. The output of the integrator 43 is supplied to a multiplier 44, where it is multiplied by a correction pulse signal from a correction pulse generator 45 and then added to the output signal of the S/H circuit 35 by an adder 46.

摘要： PROBLEM TO BE SOLVED: To reduce deviations between channels of the driving device of an LCD for performing simultaneous sampling of plural dots. SOLUTION: An amplitude component comparison circuit 42 compares a reference signal S2 with a correction object signal S3, and obtains a difference between the amplitude components of the signals S2 and S3 by synthesizing two comparison results having polarities inverted with each other. A multiplier 37 corrects the amplitude component of the signal S3 in accordance with a difference outputted from the amplitude component comparison circuit 42. A DC component comparison circuit 44 compares the signal S2 with the S3, and obtains the DC components of the signals S2, S3 by synthesizing two comparison results having the same polarities to output them to an output circuit 40. The output circuit 40 corrects the DC component of the signal S3 in accordance with a difference between the DC components of the signals S2 and S3.

摘要： PURPOSE:To constitute a projector projecting a video by a simple constitution on a screen by using a reflection type liquid crystal plate. CONSTITUTION:A first dichroic mirror 11 irradiates a first liquid crystal plate 13 with R light radiated by a light emission source 10 and its reflected light is reflected again to the side of a projecting shaft 19 by the first dischroic mirror 11. B light transmitted through the first dichroic mirror 11 is reflected by a second dichroic mirror 12, and it irradiates a second liquid crystal plate 14, and its reflected light is reflected again by the second dichroic mirro 12 and is reflected to the side of the projecting shaft 19. G light is directly made incident on a third liquid crystal plate 15 and its reflected light is set to be the projecting shaft 19. The influence of the wavelength sorting characteristic of a dichroic mirror is reduced by deciding the angle of respective optical elements so as to approach the incident angle and the outgoing angle against the normal line of respective dichroic mirror surfaces 11 and 12.
