The LCD market is moving away from cumbersome stationary display equipment toward portable (often battery operated) display equipment. Thus the need for displays which consume less power and yet are more rugged to best handle the shock and vibration requirements of a portable equipment . To address the need for more portable, energy efficient, environmentally friendly LCD displays NEC has introduced a variety of displays incorporating LED backlight systems. LED-based LCDs offer distinct advantages over their CCFL counterparts that address most, if not all, of the requirements for portable display equipment. Advantages include:

• Low Voltage displays 
• Low EMI 
• No need for an inverter 
• Reduced power consumption 
• Reduced module thickness and weight 
• High reliability 
• Lower risk of damage to the display due to shock and vibration 
• LED’s are mercury-free and therefore more environmentally friendly than CCFL products

As a total solution display provider, Optrex is addressing the need for touch screen solutions that many customers require. Optrex is introducing factory-integrated 4-wire resistive touch screens to many of their standard TFT displays. 4-wire resistive touch is the most cost-effective solution for general applications. The standard touch screens feature:

• High reliability and durability
• High accuracy
• Multiple input modes such as finger or stylus
• High transmittance (>80%)
• Wide operating temperature range
• Factory warranty (reduce contamination, failure rate, etc.)

 Touch models are currently available for the following TFT sizes: 3.5”, 5.0”, 5.7”, 6.5”, 10.4”, and 12.1”.

For higher volume OEM customers with custom touch screen requirements, such as custom tail design, 5-wire resistive touch screens, or other special requests, please contact your Avnet representative.

Hi All,

Digital View announces the following changes: 

“We have a product revision scheduled for January for the Digital View SVH-1920 and HE-1920 LCD Controllers.    The change was brought about due to discontinuance of the Samsung Memory Module used as a buffer.   The new memory has a the ability to retain user-defined color schemes, and save these schemes as “factory defaults” in a production environment.    Until the application note is released, please contact me for additional information”.

“The impact of the change to most customers is negligible, as mounting holes, edge connectors, overall dimensions and general functionality remain unchanged.   Connectors CN6 and CN9 have moved slightly, but as these are seldom used cable-to-board connectors, impact is considered minor.”

The 3M MicroTouch ClearTek EX II Touch System, an industry-standard for surface capacitive touch offerings, pairs a ClearTek II touch sensor with an EX II touch controller to create one of the most durable and accurate touch interfaces available today.  And, in respond to the increasing demand for wide-screen displays, 3M Touch Systems offers standard parts for the following popular wide-aspect display sizes: 7”, 8.9”, 12.1”, 13.3”, 17”, 18.5”, 19”, 20, 22, 24, 26, and 32”.

3M MicroTouch ClearTek II touch sensors are best known for their surface durability due to 3M’s proprietary hard coat and scratch-resistant top coat. OEM’s prefer ClearTek II sensors for contaminant-prone, heavy-use environments due to reliable operation in the presence of on-screen contaminants, such as dirt, dust and grime. They also value ClearTek II’s robust product design which features a solder less tail connection for ease of integration. 

The 3M MicroTouch ClearTek EX II Touch System is also valued for its high ESD performance, integrated ASIC, and wide operating temperatures of the EX II touch controller.

The trend for LED backlights in TFT displays are increasing at a rapid pace. More and more suppliers are offering new LCD sizes and formats on a regular basis.

NEC is introducing 5 new TFT’s incorporating a newly designed LED units that achieve both long operating life of 70,000 hours and low power consumption in the backlight system.

2. Compatibility
Each of the new modules is compatible with NEC LCD Technologies’ conventional standard products of the same size in relation to outer dimensions, position of mounting holes, and screen center. Each also maintains signal compatibility with conventional products. Thus, the modules can be replaced easily without the need to change any of their peripheral appliances.

3. Wide operating temperature range
A wide operating temperature range, from –20 to +70 degrees Celsius, guarantees operation even in extreme conditions. Moreover, the luminance of the white LED backlight performs exceptionally well under low temperatures, even from initial startup.

Material referenced above can be found on NEC’s web site:

http://www.necelam.com/news/newsdetail.html?page=long_life_low-power_white_led_for_industrial_display#1

The main characteristics of the new modules are as follows:

1. Long-Life and Low-Power White LED Unit
The newly designed white LED unit, outperforms conventional cold-cathode fluorescent lamps (CCFL) with an operating life of 70,000 hours at room temperature (25 degrees Celsius). It reaches an operating life of 60,000 hours at a high temperature of 60 degrees Celsius, and boasts high reliability that is ideal for display devices in industrial equipment exposed to severe environmental conditions. All new modules reduce power consumption by more than 20 percent compared to conventional CCFL backlight systems.

Toshiba America has released five new Industrial TFT modules that incorporate an LED Backlight with a 70,000 Hour MTBF; or, in simple terms, approximately 8 years of continuous operation (to half brightness of the initial luminance specifications).  This spec equals and exceeds what is common with traditional CCFL backlight products.  The Benefits of the LED backlights are lighter weight, lower electrical noise, low power consumption, instant “on” and better performance in cold temperatures, better shock & vibe, and a wider adjustable luminance range.  These panels are also designed with a replaceable backlight structure and Toshiba has added the LED driver circuitry to the electrical interface which simplifies design and sourcing concerns. These panels are ideal for a myriad on industrial applications:
