Molecular Crystals and Liquid Crystals. This is a milestone for implementing large-screen LCDs having acceptable visual performance for flat-panel computer monitors and television screens. This light will then be mainly polarized perpendicular to the second filter, and thus be blocked and the pixel will appear black. In the second embodiment, it is described that the single touch panel side ridge a is formed in the surface e of the insulator portion , which is opposed to the touch panel , and the single front case side ridge b is formed in the surface f of the insulator portion , which is opposed to the flange portion Thereby, the reflection of the light by the insulator portion can be limited.

Archived from the original on December 20, The spacer is a lcx and dust limiting insert member, which is seamlessly and integrally molded from a material a resilient material or the likesuch as a rubber material having some degree of hardness or a resin material having some degree of resiliency.

Archived from the original on April 23, The second embodiment is an embodiment, in which a touch panel side ridge a and a front case side ridge b hereinafter also referred to as ridges ab are added to the insulator portion in the first embodiment discussed above. Super-IPS was later introduced after in-plane switching with even better response times and color reproduction.

When no voltage is applied to a TN liquid crystal cell, polarized light passes through the degrees twisted LC layer.

Thereby, the insulator portionwhich forms the gap of the predetermined dimension between the display and the touch panel and prevents or limits the intrusion of the dust into the e152ffis additionally used to mask the front case the flange portion without increasing the number of the components, and thereby it is possible e152ff limit the deterioration of the visual quality of the display device caused by reflection of the light at the front case The display may be formed by, for example, a liquid crystal display, an organic EL display.


The outer peripheral cover portion is configured into a rectangular tubular form and covers the outer peripheral surface of the display e512f the outer peripheral surface of the touch panel The front case has a plate thickness of, for example, about 0.

The display device according to claim 8wherein the surface-textured part is formed at least in an area of the surface of the insulator portion, which is located on the side where the touch panel is located and is visually recognizable by the user through the opening of the panel frame portion.

Vertical ridges etched on the surface are smooth. Download Center Get in touch. In the present embodiment, the opening a of the panel frame portion relative to the touch panel the operating surface a is formed to be larger than the opening of the front case the flange portion relative to the lcf the display surface Retrieved February 12, Similarly, in the front case side recess btwo grooves b are formed at two opposite sides a left side and a right side in FIG.

Retrieved August 4, About product and suppliers: Supplier Types Trade Assurance. Thereby, the reflection of the light by the insulator portion can be limited. Here, an opening line position of the opening a is located on the outer peripheral cover portion side of the inner side line position b in FIG.

The frame is integrated with printed circuit board whichcontains a line of IR-LEDs and photo transistors hidden behind the bezel of the touch e152.

Dead pixel policies are often hotly debated between manufacturers and customers. InGeorge H.

Individual pixels are addressed by the corresponding row and column circuits. A surface of the cover filmwhich is located at an outer side the driver sideforms the operating surface a that is operated with the finger of the driver. Thereby, in an unassembled state of the spacervariations in dimensions of the respective parts, such as the thickness of the insulator portion and the length of the insulator portion in the extending direction, are ensured by the precision of the mold.


A position, at which the bent section b is formed, is located between the line position a in FIG.

Switching on one of the TFTs will activate the associated pixel. Archived from the original on April 1, The display unit has a display surface. Twisted nematic displays contain liquid crystals that twist and untwist at varying degrees to allow light to pass through. The front case is made of metal and is configured into a frame form, and the front case covers at least an outer peripheral part of the display surface of the display unit.

Instead of firing electrons at a glass screen, an LCD has backlight that provides light to individual pixels arranged in a rectangular grid. The LCD backlight systems are made highly efficient by applying optical films such as prismatic structure to gain the light into the desired viewer directions and reflective polarizing films that recycle the polarized light that was formerly absorbed by the first polarizer of the LCD invented by Philips researchers Adrianus de Vaan and Paulus Schaareman[56] generally achieved using so called DBEF films manufactured and supplied by 3M.

The touch panel is a position sensing device, which is transparent and is configured into a rectangular plate form that corresponds to the display
