TFT LCD Monitors are primarily discussed in our previous blogs. TFT LCDs are an everyday landscape, with TFT LCD being an extensively used display in different ways looking, from medical equipment, automobiles or advertisements, and smartphones.

One of our blogs, TFT LCD MONITOR: WHAT YOUR BUSINESS NEEDS TO KNOW, clearly mentioned how customers value Liquid Crystal Display (LCD) for the clear, high-quality images it produces. However, industry professionals are increasingly incorporating new technology into creating LCD screens. New inventions have recently taken the tech world by storm, replacing outdated LCD versions, such as the TFT LCD Monitor.

The terms reflective, transmissive, and transflective describe how LCD modules illuminate. Compared to emissive display technologies such as OLED displays (organic light-emitting diode) and VFDs (vacuum fluorescent displays), LCDs need an ambient light source like the sun, artificial light, or a merged backlight.

Some displays use ambient lighting instead of backlights. This mode of operation is termed reflective. A mirror is installed behind the liquid crystal layer in this mode, which is either on the LCD cell or the rear polarizer...Read More

It is possible to buy LCD displays where the LEDs are in parallel and these can be powered from 5V. However series connection is more common since there are plenty of low cost boost ICs you can get to drive them, and these will allow operation from a wide range of supply voltages and incorporate PWM and current regulation brightness control (not always easy to get right, especially if you are worried about colour balance).

Bridging the large format size demand between 40” and 55” TFT LCD displays. Display Technology can offer the AUO 46” high brightness displays designed for the outdoor and public information markets.

When designing new products, the majority of engineers are opting for a side-lit LED backlight display over EL (Electroluminescence), even though some LED (Light Emitting Diode) backlights may produce hot and cold spots.

EL backlight provides an estimated 3K hour half-life vs. the 50K to 90K hours provided by current LED technology. Longer half-life is important as most manufacturers no longer build products to be repaired.

Shorter half-life may not be an issue in some products where the backlight is only on for short periods of time or the product is disposable. An example of this is a portable glucose monitor, where the backlight is only on a few seconds a day.

What is a Half-Life? Half-life is the amount of time (in hours) before the backlight becomes half as bright compared to when it was first turned on. It is not the amount of time required for the backlight to completely go dark.

EL backlight requires an AC signal and most designs, including battery powered products, supply DC. This means an inverter is required. The additional components for an inverter circuit add to the overall cost of the product and also require additional real estate on the PCB that may already be overcrowded.

LED backlights are much brighter and have a greater intensity than the EL backlight. It is possible to build a LCD display with LEDs to achieve a brightness of 1,000 nits or higher.

What is a NIT? The brightness of the backlight is measured in ‘nits’. As a general rule, one nit = to the light produced by one candle. (It’s a bit more technical then that, but it works out the same)

Minimum Order Quantities (MOQ) for the EL backlight have increased from 100 to 1K in the last three years, and that number only looks to rise. A large number of products manufactured in the US have estimated usages of 200 units or less a year, a high MOQ makes it difficult to launch a product when you are required to purchase several years of inventory.

Another concern is for replacement/warranty work since a company may only repair a small number of units a year, but is forced to purchase 1K LCDs with EL backlight to hold in their warranty inventory.

The El backlight is limited in size and cannot be integrated in larger displays such as monochrome QVGA (320x240) displays. In the past CCFL (Cold-Cathode Fluorescent Lamp) replaced EL backlights on larger displays, but CCFL displays have been discontinued due to environmental reasons (such as lead) and have been replaced with multi-LED arrays. LED backlights, however, are not a drop-in equivalent for CCFL since CCFL, like EL backlights, require an AC supply.

One challenge to the white LEDs as in the photo above is that if they are too bright, they can create hot spots or polka-dots on the LCD. The best solution to the elimination of hot-spots has been to reduce the brightness of each individual LED and increase the total number of LEDs.
