摘要： PROBLEM TO BE SOLVED: To provide a touch panel of superior durability under high temperature and humidity environment, and a method of manufacturing the same. SOLUTION: This touch panel 1 comprises a pair of transparent glass substrates 1a and 2a respectively having transparent electrodes 1b and 2b, and disposed to face each other via a seal part 3. The thickness of the seal part 3 is set to 8 μm or less (excluding 0). Water contents infiltrating into between the transparent glass substrates 1a and 2a passing through the seal part 3 can thus be shut off.

摘要： PROBLEM TO BE SOLVED: To provide a stereoscopic display device where a display panel can excellently provide a stereoscopic vision from a display image while suppressing crosstalk regions. SOLUTION: Image data including parallax for both left and right eyes are written to pixels on scanning electrodes while applying a linear-sequential scanning to both scanning electrodes Y1 (1), Y2 (1) placed in the middle among a plurality of scanning electrodes on a liquid crystal display panel 10 toward scanning electrodes Y1 (n), Y2 (n) placed at both outsides in the opposite direction, respectively, the scanning electrodes hold the written image data so as to receive the linear-sequential scanning and a plurality of the scanning electrodes are controlled to delete the held image data to expel a crosstalk region toward edges on the display panel.

摘要： PROBLEM TO BE SOLVED: To obtain a plural-video display device by which the resolution of a video is enhanced by devising an optical system and utilizing high speed display changeover by time division. SOLUTION: Both right and left light sources 20 and 30 are arranged on both sides of an aperture part 11a on the side of a front wall 11 at the inside of a casing 10. A reflector 40 is arranged along the rear wall 12 of the casing 10, so that surface-like light having a reverse phase from both light sources 20 and 30 is reflected to the aperture part 11a. A liquid crystal panel 10 is provided at the aperture part 11a at the inside of the casing 10 together with a condensing lens 50. Reflected light from the reflector 40 is condensed by the condensing lens 50 and is condensed at both eyes of either left or right observer by passing through the liquid crystal panel 60. Respective videos for the left and right observers are switched and displayed by high speed by the timed division with light from the condensing lens 50 at the liquid crystal panel 60.

摘要： PROBLEM TO BE SOLVED: To provide a stereoscopic display device, where the configuration of the optical system is aimed at preventing a crosstalk area from being produced and a liquid crystal display element is large-sized. SOLUTION: A light source 10 is placed behind an object point side focus of a linear Fresnel lens 30. Thus, a light passing through each 1/2 wavelength plate of a polarized plane rotary plate 40 in a linearly polarized light (right eye use collected light of the Fresnel lens 30) from a right eye use polarized plate section 11 of the light source 10 passage through each of odd numbered horizontal strip pixel sections 51a of a liquid crystal display panel and is converges to only a right eye IR, whereas, a light passing through each half-wave plate of the polarized plane rotary plate 40 in a linearly polarized light (left eye use collected light of the Fresnel lens 30) from a left eye use polarized plate section 12 of the light source 10 passes through each of even numbered horizontal strip pixel sections 51a of the liquid crystal display panel and converges to only a left eye IL.

摘要： PROBLEM TO BE SOLVED: To provide a stereoscopic picture display device by which a stereoscopic picture of a liquid crystal display panel is viewed as a virtual image through an output optical system without causing as thenopia by changing the position of the liquid crystal display panel. SOLUTION: When the depth of the virtual image of a stereoscopic picture to be reproduced is small, the position of the virtual image with respect to the stereoscopic picture on a color liquid crystal display panel 30 approaches positions of both left right eyes IL, IR of a viewer M by approaching the color liquid crystal display panel. On the other hand, in the case that the depth of the virtual image of the stereoscopic picture to be reproduced is large, the color liquid crystal display panel 30 is made away from the projection lens 40.

摘要： PROBLEM TO BE SOLVED: To provide the stereoscopic video image display device that effectively utilizes a light diffusion plate so as to attain a bright stereoscopic display with a high utility rate of light regardless of a small number of light sources. SOLUTION: A mirror drive circuit drives a rotary mirror 20 to set a rotary angle of the rotary mirror 20 so that a image forming light from a convex lens 40 is in matching with positions of both eyes of a viewer in response to the positions of both the eyes of the viewer detected by a CCD camera 70. Then the rotary mirror 20 changes a traveling direction of the light from the convex lens 10c and emits the light to a Fresnel lens 31 as a converted light, which makes the converted light incident into a light diffusion plate 32 as a parallel light. Thus, the light diffusion plate 32 emits diffused lights. Moreover, a liquid crystal display panel drive circuit 130 drives in time division a liquid crystal display panel 50 based on a stereo video output from a video tape recorder 110. Then a convex lens 40 forms the diffused lights from the light diffusion plate 32 into an image and the liquid crystal display panel 50 receiving the image light from the convex lens 40 displays the image stereoscopically.

摘要： PROBLEM TO BE SOLVED: To display an excellent stereoscopic video image independently of a position deviation of a viewer under a bright viewer image by photographing a viewer image not via a video display liquid crystal display panel while ensuring accurate self-tracking to the viewer. SOLUTION: A time division lighting position variable light source 10 allows both left right adjacent light source sections among a plurality of light source sections 11 to emit left and eight eye visual lights to both eyes of a viewer M through a Fresnel lens 20, a liquid crystal display panel 30, and a beam splitter 40. An image sensor 60 receives a near infrared ray of a lighting light source 70 reflected from the face of the viewer M via the beam splitter 40 and a Fresnel lens 50. Both left right adjacent light source sections 11 to be turned on in the time division lighting position variable light source 19 corresponding to the position of the viewer M are decided by using the result of light reception.

摘要： PROBLEM TO BE SOLVED: To secure a frame rate similar to the case without a recovery period, that is, a short frame period by making a scanning voltage both voltages (positive and negative) of a pulse shape and simultaneously applying a recovery voltage higher than a hold voltage to a scanning electrode. SOLUTION: For successively scanning from scanning electrode Y1 to scanning electrode Yn, the voltage is applied to the scanning electrodes after the scanning electrode Y2 with a waveform shifting by a selection period. At this time, for preventing a flicker in a display, voltage polarity at every scanning electrode is constituted so as to be inverted such as that, e.g. the scanning electrode Y1 is positive, and the scanning electrode Y2 is negative,.... Further, respective recovery periods from the scanning electrode Y1 to Yj are provided at the timing that the selection period from the scanning electrode Y1 to Yj among the scanning electrodes Y1 to Yn is ended. The selection voltage of the selection period consists of both voltages of positive or negative pulse shape, and respective recovery periods of the scanning electrodes are provided at the timing that the selection period from the scanning electrode Y1 to Yj is ended.
