wxga tft display resolution price

A new high resolution, 8.0" Lite+ TFT display has been introduced by industrial LCD manufacturer, KOE. The TX20D201VM2BAB features WXGA resolution (1280x768px) with a 16:9 wide aspect ratio. The 8.0" display has a pixel pitch of 0.13575x0.13575mm, which equates to a pixel density of 187ppi (pixels per inch). The new TX20D201VM2BAB display module is mechanically compatible with existing KOE 8.0" WVGA (800x480px) TX20D33VM2BAA, TX20D34VM2BAA, and TX20D34VM2BAB display modules.

The high resolution WXGA (1280x768px) TFT display provides a significantly higher pixel density - an increase of 60% - when compared with industry standard 8.0" WVGA displays with 117ppi.

The display brightness is specified at 900cd/m², and combined with a contrast ratio of 500:1, the Lite+ display produces images that are bright, clear and concise. The white LED backlight, features a 50,000 hours to half brightness lifetime specification.

Jason Tsai, Marketing Manager, KOE, said: "Many infotainment and user interface applications are demanding higher resolution displays to enable accurate reproduction of images and video to be presented. The new 8.0" WXGA display allows KOE to embrace the increasing market demand for high performance, high resolution displays."

A 20 pin LVDS interface supports 6 or 8-bit RGB colour data which enables a colour palette of 262,000 or 16.7 million colours respectively. The 8.0" display module has mechanical outline dimensions of 189.0x120.0x7.5mm and an active LCD area of 173.76x104.26mm. The display has an operating and storage temperature range of -30 to 80°C. The module weighs 160g.

KOE"s Lite+ TFT modules offer cost effective LCD solutions that feature industry standard screen sizes, display resolutions and data interfaces but without any compromise in display optical performance. Lite+ display modules offer high brightness display characteristics and are suitable for use in bright ambient environments.

The new 8.0" WXGA display is suited for industrial user interface, security, medical, and infotainment applications where a high resolution display is required to accurately represent display images and information, and video reproduction. The new KOE TX20D201VM2BAB Lite+ display module is available immediately through KOE"s distribution sales channel partners.

Focus Displays offers a wide range of standard full color TFT displays. 64 million unique colors, high brightness, sharp contrast, -30C operating temperature, and fast response time are all good descriptions of a TFT display. This is why TFT technology is one of the most popular choices for a new product.

Thin Film Transistor (TFT) display technology can be seen in products such as laptop computers, cell phones, tablets, digital cameras, and many other products that require color. TFT’s are active matrix displays which offers exceptional viewing experiences especially when compared to other passive matrix technologies. The clarity on TFT displays is outstanding; and they possess a longer half-life than some types of OLEDs and range in sizes from less than an inch to over 15 inches.

CCFL’s are still available, but are becoming a legacy (obsolete) component. TFT displays equipped with a CCFL require higher MOQs (Minimum Order Quantities) than displays with LED backlights.

The majority of TFT displays contain a touch panel, or touch screen. The touch panel is a touch-sensitive transparent overlay mounted on the front of the display glass. Allowing for interaction between the user and the LCD display.

Some touch panels require an independent driver IC; which can be included in the TFT display module or placed on the customer’s Printed Circuit Board (PCB). Touch screens make use of coordinate systems to locate where the user touched the screen.

Resistive touch panels are the lowest cost option and are standard equipment on many TFT modules. They are more common on smaller TFT displays, but can still be incorporated on larger modules.

Contrast ratio, or static contrast ratio, is one way to measure the sharpness of the TFT LCD display. This ratio is the difference between the darkest black and the brightest white the display is able to produce. The higher the number on the left, the sharper the image. A typical contrast ratio for TFT may be 300:1. This number ratio means that the white is 300 times brighter than the black.

TFT LCD displays are measured in inches; this is the measurement of the diagonal distance across the glass. Common TFT sizes include: 1.77”, 2.4”, 2.8”, 3”, 4.3”, 5”, 5.7”, 5.8”, 7”, 10.2”, 12.1 and 15”.

As a general rule, the larger the size of the glass the higher the cost of the display, but there are exceptions to this rule. A larger display may be less expensive than a smaller display if the manufacture produces higher quantities of the larger displays. When selecting your color display, be sure to ask what the cost is for one size smaller and one size larger. It may be worth modifying your design requirements.

TFT resolution is the number of dots or pixels the display contains. It is measured by the number of dots along the horizontal (X axis) and the dots along the vertical (Y axis).

The higher the resolution, the more dots per square inch (DPI), the sharper the display will look. A higher resolution results in a higher cost. One reason for the increase in cost is that more driver chips are necessary to drive each segment.

Certain combinations of width and height are standardized and typically given a name and a letter representation that is descriptive of its dimensions. Popular names given to the TFT LCD displays resolution include:

Transmissive displays must have the backlight on at all times to read the display, but are not the best option in direct sunlight unless the backlight is 750 Nits or higher. A majority of TFT displays are Transmissive, but they will require more power to operate with a brighter backlight.

Transflective displays are readable with the backlight off provided there is enough ambient light. Transflective displays are more expensive than Transmissive also there may be a larger MOQ for Transflective. However, Transflective displays are the best option for direct sunlight.

Drivers update and refresh the pixels (Picture Elements) of a display. Each driver is assigned a set number of pixels. If there are more pixels than a single driver can handle, then an additional drivers are added.

A primary job of the driver is to refresh each pixel. In passive TFT displays, the pixel is refreshed and then allowed to slowly fade (aka decay) until refreshed again. The higher the refresh frequency, the sharper the displays contrast.

The controller does just what its name suggest. It controls the drivers. There is only one controller per display no matter how many drivers. A complex graphic display with several thousand pixels will contain one controller and several drivers.

The TFT display (minus touch screen/backlight) alone will contain one controller/driver combination. These are built into the display so the design engineer does not need to locate the correct hardware.

If you do not see a Thin Film Transistor (TFT) Display module that meets your specifications, or you need a replacement TFT, we can build a custom TFT displays to meet your requirements. Custom TFTs require a one-time tooling fee and may require higher MOQs.
