SHARP UV2A : Sharp va intégrer la technologie UV2A aux LCD

La prochaine génération de dalle LCD devrait provenir de la société Japonaise Sharp. En effet, le constructeur Japonais vient de présenter son plan pour l'ajout de la technologie UV2A dans les prochaines productions de LCD.

Alors qu'est ce qu'il y a de si intéressant concernant cette information? Et bien, que cette technologie devrait grandement aider les constructeurs de TV 3D. En effet, cette technologie devrait améliorer d'une part le temps de réponse des dalles LCD, mais d'autre part devrait apporter un meilleur rapport de contraste avec un minimum de 5000:1, pour un noir encore plus profond. Sharp parle également d'une "reproduction visuelle" améliorée de 20%.

Ayant été un fier possesseur de TV Sharp Aquos, je peux vous dire que j’attends ces nouvelles dalles avec une grande impatience!



Sharp Corporation has developed a photo-alignment technology called UV2A Technology for LCD panels that can precisely control the alignment of liquid crystal molecules in a simple LCD panel structure. Sharp will fully incorporate this world-first technology as a core technology for the production of a new type of LCD panel that will significantly evolve LCD TVs to the next generation.

The ASV (Advanced Super View) technology thus far adopted by Sharp delivers high-resolution images to LCD TVs by precisely controlling the movement of liquid crystal molecules within a complex LCD panel structure. The next generation of TVs, however, must deliver groundbreaking performance in terms of image resolution and energy efficiency. That will require not merely an extension of past developments, but rather further innovation in LCD technology itself.

Thus Sharp has adopted a special material that responds to UV (ultraviolet) radiation and has developed UV2A Technology as a photo-alignment technology for the alignment film in LCD panels. This innovative technology, the result of combining proprietary materials developed by Sharp with UV exposure equipment and processing technologies, provides highly accurate control over the alignment of liquid crystal molecules in accordance with the direction of the radiation. It can be termed “pico-technology” in that it goes beyond nanotechnology to control the tilt angle of liquid crystal molecules, which are only around two nanometers*4 in size, with an accuracy measured in picometers.*5

In addition to eliminating light leakage from the backlight, making it possible to display extremely deep blacks, this technology also enables higher aperture ratios in the LCD panel for the most efficient use of light from the backlight, thereby saving energy while displaying bright, vivid colors. Sharp’s UV2A Technology will also be ideal for enhancing the performance of high-definition 4Kx2K displays and 3D TVs, which are expected to form the next generation of TVs.

Sharp will be introducing this technology across the board for panels to be produced at the new LCD panel plant in Sakai and at Kameyama Plant No. 2.
