The Sony CLIE VZ90 has an interesting form-factor. It is a tablet disign. It is larger than the Sony CLIE UX50 and uses�a slider design. This is not like the slider on the palmOne Tungsten T3, but rather a set of controls that slides out from underneath the display.
Here are the specs:
- 480-by-320-pixel display, 3.8" diagonal
- Palm Garnet (OS 5.2.1 Japanese version)
- 128 MHz Sony Handheld Engine
- 64 MB of RAM, 40 MB�available to the user
- 128 MB of ROM,�95 MB available to the user
- Compact Flash II Slot (handles both memory cards and peripherals)
- Sony Memory Stick PRO slot
- Built-in Wi-Fi (no Bluetooth)
The Sony CLIE VZ90 will be onsale in Japan (only) on September 25, 2004 for 89,800 Yen (about $820).
ClieClub in Japan has a nice pictorial of the VZ90.
Sony Begins Mass Production of Full-Color Organic Light Emitting Diode (OLED) Displays
New Thin Screens for Mobile Devices Realize CRT-Quality Picture Clarity and Color Gamut
This month, Sony Corporation will commence mass production of a full-color Organic Light Emitting Diode (hereafter OLED) display, which will be first implemented in the new Sony CLI� �PEG-VZ90� personal entertainment handheld (also announced today for the Japanese market).
OLED display is a self-luminous display that does not require a back-light, offering high contrast ratio, a quick response time and wide viewing angle�all in a package slimmer than current LCD modules.� To enhance this display, Sony has employed its unique Super Top Emission� technology for outstanding brightness and greater color gamut.� These translate into image quality and clarity that could previously viewed only on CRT (cathode ray tube) displays.�
The new 3.8-inch (or 9.7 cm) screen measures 2.14 mm thin, and makes it possible for users to enjoy a variety of high-quality content such as TV programs and digital still images on mobiles products such as the new CLI� VZ90 handheld without compromising on the viewing experience.�
Key Features
1. Super Top Emission
As the name implies, Super Top Emission leads light emission from the upper side of the organic material, realizing a brightness level of 150cd per square meter. Also, by optimizing the thickness of the organic layer for each of the color components, RGB, Sony realized multi-interference of reflecting light.� Additionally, with the cavity multi-reflection interference structure which enables emission of colors with high purity, bright and brilliant color gamut comparable to that of CRT is realized
��
2. Excellence in response time, viewing angle and contrast ratio
As OLED works with self-luminous organic materials, it has outstanding response time, without producing any afterimage even when displaying moving images (movies). Also with wide viewing angle and contrast ratio as high as 1000:1, high quality images can be realized on mobile products which are used in various occasions.
