Recent 'Winstar Display' News

The WEO012832D/F from Winstar is a popular small OLED display series with built-in SSD1303BZ IC controller. With a diagonal size of 0.91”, 128x32 pixels, these displays are specifically designed for wearable devices.

Winstar Display has two new compact OLED displays the WEO012832D and the WEO012864D which are very suitable for wearable devices, these displays are very small and have a built-in SSD1303 IC controller.

The WEO012832D is 0.91 inch 128x32 module (one of the most popular sizes for wearable devises) and an outside dimension of 30 x 11.5 mm.
The WEO012864D is a 0.96 inch 128x64 module with a total dimension of 26.7 x 19.26 mm. The displays have an operation temperature from -40176C till +80176C.

Winstar provides Character OLED display and Graphic OLED modules. They offer COB/COG/TAB construction PMOLED.
PMOLED do not require any backlight and filtering systems.

PMOLED stands for Passive-Matrix OLED, which relates to the way you control the display. A PMOLED display uses a simple control scheme in which you control each row (or line) in the display sequentially (one at a time).
PMOLED electronics do not contain a storage capacitor and so the pixels in each line are actually off most of the time. To compensate for this you need to use more voltage to make them brighter.

PMOLED displays are restricted in resolution and size. PMOLED displays are usually small (up to 3" typically) and used to display character data or small icons: they are being used in wearable devices, small gadgets and sub displays.

Winstar has formfit replaceable PMOLED displays in her portfolio, to exchange existing STN and FSTN designs.

PMOLED Displays are available in Yellow / Green / Red / White / Blue.

The WFxxQ-series from Winstar is a family of TFT modules which all have the same 36-pinout connector on the SSD1963 controller board. Using the same interface offers you the flexibility of choosing between display sizes without the need of adjusting the design of your application. The WFxxQ series includes 3.5", 4.3", 5.7", 7.0", 8.0" and 10.2" module sizes.

The WFxxQ Series feature 8-bit or 16-bit parallel interface option, pin 33 to 36 are already defined as backlight supply; there is no need to design an extra backlight circuit.

The Winstar TFT WFxxQ series provides innovative advantages, offer outstanding image quality and are easy to use.

•  Onboard SSD1963 controller, same 36 pin connector
•  8 bit and 16 bit parallel interface options
•  Module sizes interchangeable
•  Pin 33 to 36 are already defined as backlight supply
•  Built-in backlight driver IC
•  All displays support an 5.0V input supply (3.5" and 4.3" also support 3.3V)
•  No need for changing of the backlight driver circuit if module size changes
•  Sleep mode option available on 5.7", 7.0", 8.0" and 10.2" displays
•  Resistive and capacitive touch screen options

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.

Winstar Display released a new version of the standard WH1602B series. The WH1602B is a 2x16 character display with a VATN LCD (Vertically Aligned Twisted Nematic) that provides sharper contrast, high brightness and great viewing angle. VATN displays operate in a negative mode with a transmissive polarizer and are therefore easier to read in dark environments.

The built-in controller IC of the WH1602B allows you to choose between the following interface options: 6800 parallel, 4 line SPI or I2C. Each interface option has a different model number. The displays are available in 5 colors, white, green, red, blue, yellow/green.

About Vertical alignment (VA) displays: When no electric current is running through the liquid crystal cells, the cells naturally align vertically between two substrate panes of glass which blocks the transmission of light from the backlight. This renders the crystals opaque and results in a black display screen.
When an electric current is applied, the liquid crystal cells shift to a horizontal position between the substrates allowing light to pass through resulting in a white display screen.
