Winstar offers different sizes of Bar type, color TFT-LCD displays such as 3.9, 4.6 and 5.2 inch. In the market the most popular ratio of a TFT LCD panel is 4:3 or 16:9, but for a lot of applications a bar type shape of display panel would be much better.
The 4Duino-24 is an 2.4 inch Arduino IDE programmable display module that combines the uLCD-24PTU, Arduino Leonardo, and ESP8266 WIFI. Packed with features this standalone module brings you great graphics, resistive touch capability and internet access; making it perfect for Arduino based IoT applications.
The gen4 series from 4D Systems is a new range of slim and sleek display modules with a new optional optically bonded cover lens bezel for seamless and cost effective integration of a Graphical User Interface to virtually any application. These display modules are designed specifically for ease-of-use and rapid development cycles, with careful consideration for space requirements and functionality.
The WF57S and WF62A series from Winstar are monochrome graphic TFT displays with a diagonal of resp. 5.7 and 6.2 inch. The TN positive LCD, applied in the active matrix TFT, results in high contrast/brightness and short response times. In short, the mono TFT display performance is much better in contrast, brightness and response time than traditional monochrome LCD module. These displays are sunlight readable.

Driving these displays is easy. There is no need for an external controller board to drive the MCU control, yet they still offer the same performance characteristics as full color TFTs.

Depending on the setting these displays can operate in 2, 4 and 16 shades of gray scale modes. The WF57S and WF62A series support several user selectable communication modes : 3 - or 4-line serial interface and an 8 -bit parallel interface compatible with standard systems with 8080 or 6800 family.
Also worth mentioning is the option to turn the device into a sleep mode without clearing the memory contents of the display.

These high performance monochrome TFT-LCDs are the ideal solution in circumstances where there are fewer requirements for full color displays such as automotive and industrial applications.

The CH070OLDL-002 from Chefree is an 7" enhanced Superbright LED LCD. This high bright, sunlight readable TFT with an 16:9 aspect ratio is driven by a 6-bit LVDS interface and a brightness of 1000 cd/m2 output. View angles are 110° (vertical) and 140° (horizontal) with 262K colours and a contrast ratio of 400. The CH070OLDL-002 features a built-in LED driver and a 12-hour view.

These displays are aimed at outdoor use where reflective light is an issue. Operating temperature range is -20° to +70°C making them ideal for hash environments. The LED backlight has excellent longevity and contributes to the overall low energy use.

Every unit can be further enhanced with sunlight readable filters and Protection glass or touchscreen bonding with Resistive or Projective Capacitive Touch technology.
