摘要： Though a driver circuit including a DA converter and provided in a peripheral area is integrated with a pixel part by using polycrystalline Si TFT, the fixed pattern noise caused by the variation of the threshold voltages of the DA converter and a buffer circuit is eliminated. A pixel common electrode is independently provided for each signal line, and the output of the buffer circuit is connected to both the common electrode and the signal line through a switch. Since the variation of the threshold voltage of the buffer circuit is cancelled between the common electrode and the signal line, the fixed pattern noise can be eliminated.

摘要： PROBLEM TO BE SOLVED: To sufficiently enable a recording magnetic field at a narrow track width and to reduce recording bleed by setting the width of the throat height part of magnetic cores narrower than the width from the end reverse from the air bearing surface position of a pole height part to the end reverse from the air bearing surface position of the throat height part. SOLUTION: A ground surface film 12, a lower magnetism shielding film 13, a lower gap film 14, an MR sensor film 15, an electrode film 16, an upper gap film 17 and an upper magnetism shielding film 18 are formed on a substrate 11. A lower magnetic core 20 is formed across a separating film 19 on the upper magnetism shielding film 18. Otherwise, the separating film 19 and a lower magnetic core 20 are formed at the discrete pattern widths after the upper magnetism shielding film 18 is formed. Gap films 21, coils, interlayer insulating films and an upper magnetic core 22 are successively laminated and the width of the non-working portion of the ball height part is made larger with respect to the width size of the throat height part subjected to convergent ion beam processing to the shape that the width is reduced to the size corresponding to the track width of the recording medium at the throat height part, by which the deterioration in the recording magnetic field is prevented.

摘要： PROBLEM TO BE SOLVED: To make it possible to avert the increase of a signal input frequency and the occurrence of problems in packaging when the number of pixels increases by integrating frame memories with a display. SOLUTION: The pixels comprising TFT switches 1, pixel electrodes connected to their source electrodes and pixel capacitors 2 consisting of common electrodes are arranged in a matrix. Gate lines 3 are connected to the gates of the TFT switches 1. The one-side ends of the gate lines 3 are provided with perpendicular shift registers 5. Signal lines 4 are connected to the drains of the TFT switches 1 and the one-side ends of these signal lines 4 are provided with DA converters 6. The common electrodes 8 of all the pixels are connected to one and a specified voltage is impressed thereon. As a result, the problems in packaging do not arise even if the number of the pixels is increased and the signal input frequency is increased. Even if the frame memories are formed on the same substrate as the substrate of the pixels, the generation of unsightly interference noises is averted.
