white backlit lcd module free sample

A:We are professional manufactory, which specializes in TN, HTN, FSTN, STN monochrome LCD, LED backlights, LCD modules more than 10 years in Shenzhen!

This graphic LCD module acts as a shield for Arduino Uno-style microcontrollers. The pins on the carrier board match up to the Arduino Uno"s ports, so the module simply presses on and is fully and correctly connected. Plus, this carrier board is able to be connected to either a 3.3v logic level or a 5v logic level device. (Read our blog post if you have questions about logic level.)

This module is also available with a white-on-blue graphic display, or as a fully built kit with an included Seeeduino (Arduino Uno clone) loaded with code to demonstrate the graphic display.

Newhaven 40x4 character Liquid Crystal Display shows characters with dark pixels on a bright white background when powered on. This transflective LCD Display is visible with ambient light or a backlight while offering a wide operating temperature range from -20 to 70 degrees Celsius. This NHD-0440WH-ATFH-JT# display has an optimal view of 6:00 and comes English and Japanese standard font. This display operates at 5V supply voltage and is RoHS compliant.

Newhaven 128x64 graphic Liquid Crystal Display module shows white pixels on a black background. This transmissive LCD Display requires a backlight for visibility and offers a wide operating temperature range from -20 to 70 degrees Celsius. This NHD-12864WG-FTTI-VZ#000 display includes a 2x10 straight vertical header as well as built-in negative voltage. It has an optimal view of 6:00, operates at 5V supply voltage and is RoHS compliant.

Lumex LCD module with Built-in SSD1306 I2C Interface, LCM-H12864GWN-WI2C, is the newest product belongs to Lumex Display Adapting Service. LCM-H12864GWN-WI2C is graphic type transflective LCD in 128*64 pixels with white backlight. With built-in SSD1306 I2C interface, LCM-H12864GWN-WI2C is able to direct replace most 128 x 64 pixels OLED in the market.

Typical LCDs are edge-lit by a strip of white LEDs. The 2D backlighting system in Pro Display XDR is unlike any other. It uses a superbright array of 576 blue LEDs that allows for unmatched light control compared with white LEDs. Twelve controllers rapidly modulate each LED so that areas of the screen can be incredibly bright while other areas are incredibly dark. All of this produces an extraordinary contrast that’s the foundation for XDR.

Converting blue light to white is a difficult process that requires extremely precise color conversion. It’s why most display makers use white LEDs. Pro Display XDR accomplishes this conversion with an expertly designed color transformation sheet made of hundreds of layers that control the light spectrum passing through them.

With a massive amount of processing power, the timing controller (TCON) chip utilizes an algorithm specifically created to analyze and reproduce images. It controls LEDs at over 10 times the refresh rate of the LCD itself, reducing latency and blooming. It’s capable of multiple refresh rates for amazingly smooth playback. Managing both the LED array and LCD pixels, the TCON precisely directs light and color to bring your work to life with stunning accuracy.

Dr Pan: Hello, Greg. Character LCD module is one special dot matrix LCD Module with stationary size and resolution, operation voltage, interface, etc.

Take 20*2 character LCD module for example. There are 20 characters horizontally, 2 characters vertically. Each character is a 5*8 dot matrix. Outer dimension 116.0×37.0 mm and active area 73.5×11.5 mm. When you develop a custom dot matrix LCD module, it can be any length and width, resolution, but it takes a lot of time and great efforts to develop it. The most widely used dot matrix LCD modules with specific sizes were made public and it is very convenient for everyone to get them with no tooling fee. You will not have a lot of options when you choose a character LCD module, a custom dot matrix LCD module is still your first choice.

TFT LCD image retention we also call it "Burn-in". In CRT displays, this caused the phosphorus to be worn and the patterns to be burnt in to the display. But the term "burn in" is a bit misleading in LCD screen. There is no actual burning or heat involved. When you meet TFT LCD burn in problem, how do you solve it?

When driving the TFT LCD display pixels Continously, the slightly unbalanced AC will attract free ions to the pixels internal surface. Those ions act like an addition DC with the AC driving voltage.

For normal white TFT LCD, white area presenting minimal drive, black area presenting maximum drive. Free ions inside the TFT may are attracted towards the black area (maximum drive area)
