FREMONT, USA: Reach Technology Inc. has announced a new 7-inch display module that gives customers access to the wide WVGA screen size that offers extended control area. The module uses a 7-inch LED backlight TFT panel suitable for industrial, long-life applications.
Reach Technology's 7-inch module comes complete with an SLCD5 controller board, LCD, backlight driver, and touch screen. Reach's display module technology and simple-to-use programming tools make GUI interface and integration easy. This helps customers reduce time-to-market and development costs. The company is in full production.
The 7-inch LCD is an ideal size for a broad range of control surfaces. The wide screen ratio creates an ideal user interface space and gives customers looking for a screen larger than 5.7-inches a good value. Even though the 7-inch module is nearly as wide as the 8.4-inch module, it costs 40 percent less.
“We created the 7-inch module when one of our medical customers needed a screen bigger than the 5.7-inch, but at a lower price point than the 8.4-inch," said Jonathan More, President for Reach Technology. “This 7-inch display module gives our customers good bang for the buck.”
Module specifications
The display resolution is 800x480 pixels (WVGA) with a luminance of 280cd/m2, contrast ratio of 400:1, and uniform viewing angle of 130 degrees. A high bright 400cd/m2 option is available.
The module has a steel mounting bracket with convenient mounting holes that makes the display easy to mount. Power requirement is 5VDC, and two serial interfaces are supplied.

NEC LCD Technologies develops white LED-based LCD module
TOKYO, JAPAN & SANTA CLARA, USA: NEC LCD Technologies, and its sales and marketing channel in the Americas, NEC Electronics America, Inc., announced the development of a new amorphous-silicon color TFT-LCD module that achieves an ultra-wide color gamut for 100 percent of the Adobe RGB color range by incorporating a newly developed LED light-source unit into the backlight system and a newly developed color filter.
The white LED that serves as the light source for the backlight unit in this LCD module achieves its white light by mixing light generated through the irradiation of red, green, and blue (RGB) phosphors with light from a near-ultraviolet LED chip (excitation), making it superior to traditional white LEDs in terms of color-rendering properties.
Combining these newly developed white LEDs with newly developed color filters, optimized for this application, makes it possible to reproduce a wider range of colors covering 100 percent of the Adobe® RGB color range, which is generally beyond the reach of conventional standard white LEDs.
In recent years, there has been an increase in customer demand for LCD displays using white LEDs as light sources in backlight units due to the many benefits achieved with LED backlight systems versus cold-cathode-fluorescent-(CCFLs)-based backlights. Such benefits include smaller module dimensions, lighter-weight designs, and reduced power consumption.
The LEDs are also mercury free and do not require the use of high-voltage circuitry, allaying concerns related to safety and the generation of harmonic currents and high-frequency noise. The LEDs offer superior vibration and shock resistance as well as superior characteristics with respect to low-temperature startup and a wider dimming range.
The white LEDs currently in widespread use typically have weaker output in their red and green wavelength components than CCFLs, since they create white light by exciting the yellow phosphors that cover the blue LED chips. For this reason, when used as backlight light sources, traditional white LEDs, even when combined with color filters having a wide color gamut, impose limits on the expansion of the red and green color reproduction range, making it difficult to cover the Adobe® RGB color range.
NEC LCD Technologies overcame these problems with its newly developed LCD module that is compatible with applications requiring an ultra-wide color gamut, a capability difficult to achieve with traditional white LEDs.
