TFT LCD Display Factory FAQ

What is LED Backlit in LCD?

LCD or TFT uses LED Backlit (light-emitting diode) behind or around the edge of display instead of reflected light. LED Backlit is used to illuminate liquid crystals and produce visual images.

TFT LCD modules operate at 3.3V?

Yes, TFT operates at both 2.8V - 5V. However, as the 3.3V becomes the new standard. Please refer to the model specifications for details for voltage and power requirements.

What are the interfaces available with LCD Displays?

Interfaces: QSPI, I2C, 3/4-line SPI, RGB, MCU, LVDS, MIPI,EDP etc.

What are the operating temperature ranges for a Glomore Electro-Tech LCD display?

Operating Temperature: -20 ~ 70°C and Automotive grade +80°C, Please refer individual specification for more details.

TFT display are available with Touch screen Options?

Yes, available with Resistive or Capacitive touch screen as single piece or unit.

Can provide initialization codes for their modules?

Yes, we can, even you can find initialization codes in some technical sheet itself.

Does provide any Support?

Yes, Hongcai-Tech does help end user to select right product to meet technical-commercial requirements along with initialization code to kickstart the project.

Does help in LCD customization?

Yes, we have an expertise in TFT LCD ,Touch screen customization under various technology such as TN, VA TN, STN, FSTN and TFT along with various features, display mode, Polarizer and viewing angles.

Is the response time of your TFT LCDs good enough for moving picture?

Yes. response time is good enough for moving picture. Please check the individual display specification for detail information.

What are the common types of LCDs used in the market?

TN, STN, TFT Displays are supposedly the most common type of display units found in Consumer and Industrial market segment.

Does provide initialization codes for their modules?

Yes, we can provide the initialization codes for almost all Displays.

What is the Difference Between a TFT, LCD, and OLED?

TFT displays are also known as an “Active Matrix TFT LCD module” and have an array of thin film transistors fabricated on the glass that makes the LCD. There is one of these transistors for each pixel on the LCD. LCDs use voltage applied to a field of microscopic liquid crystals to change the crystal’s orientation, which in turn changes the polarization of the liquid crystal which creates light or dark pixels on the display.These pixels are arranged to create characters or graphic images. This type of display may be sunlight-readable and may have a backlight, which allows it to be viewed in dark areas.

Are UL certifications available for LCDs?

As a whole LCD display does not need UL certification, though, some of the components like PCB and wires used for backlight.

Do Hongcai-Tech Display LCDs have CE certification?

CE certification is typically for end products. Since the LCD is a component, so it does not require CE certification.
