Product Description

Product Description

 

Are Tsingtek LCDs RoHS compliant?
Absolutely! Every Tsingtek LCD is crafted in full compliance with RoHS standards, ensuring eco-friendly products for a sustainable future.

Are UL certifications available for Tsingtek LCDs?
The full LCD display module itself doesn't necessitate UL certification, but rest assured that its integral components, such as the PCB and backlight wires, proudly bear the UL certification mark.


What is the distinction between a Digital TFT and an Analog TFT?
The distinction lies within the interface signals. A Digital TFT welcomes digital interface signals such as TTL and LVDS, while an Analog TFT is designed to embrace analog RGB, NTSC, and PAL interface signals.

What is the lifetime spec for a Tsingtek LCD backlight?
Boasting impressive longevity, the lifetime for both White LED and CCFL backlights is rated at up to a remarkable 40,000 hours, ensuring exceptional performance and reliability.

Can I control the backlight brightness?
The CCFL frame rate can be modulated to operate at full voltage for a smaller time percentage.
This may introduce some noise, offering limited control over CCFL brightness. However, LED backlight brightness can be adjusted more seamlessly, achieved through backlight DC-current regulation, PWM control, or specialized LED drivers (IC) integration.

How is the brightness of an LCD module defined?
Brightness is defined as the average across nine distinct surface areas of the display. The surface is methodically divided into nine equal sections, with brightness measured at the center of each, ensuring precise and uniform brightness.

How is the contrast ratio of an LCD module defined?
The brightness is meticulously measured when the LCD is in a "white state."
Contrast Ratio (CR) = ----------------------------------------------------------------------
Brightness is also measured when the LCD is in a "black state," giving a comprehensive measure of contrast ratio.

How is the resolution of an LCD module defined?
Resolution is defined by the total count of color pixels across the LCD module's surface area, calculated as the product of pixel numbers in both rows and columns.

What are the standard resolutions?

QVGA:	320(H)x240(V) pixel 240(H)x320(V) pixel	2.2" , 2.4" , 3.2" , 3.5" , 5.7"
WQVGA:	480(H)x272(V) pixel	4.0" , 4.3"
VGA:	640(H)x480(V) pixel	5.6" , 5.7" , 10.4"
WVGA:	800(H)x480(V) pixel	5.0" , 7.0" , 10.2"
VGA:	800(H)x600(V) pixel	7.0" , 8.0" , 10.4"

What is LCD response time?
Response time denotes the duration a pixel takes to transition from black to white and back to black, measured in milliseconds (ms). Lower values signify more rapid transitions, thus ensuring smoother, more fluid images.

What do the RGB bits represent?
A pixel comprises three colors: red, green, and blue, with each color's saturation level altering to form a spectrum. This saturation level is depicted by bits, with the bit count representing the power of 2. For instance, 8 bits for red equate to 256 saturation levels. A 24-bit LCD module allocates 8 bits each to red, green, and blue, enabling the display of 16.8 million vibrant colors.

What is TFT?
TFT-LCD, or thin-film transistor liquid-crystal display, incorporates liquid crystals contained between two glass substrates to regulate light passage. The front glass holds the color filter, while the back has transistors. Voltage application bends the liquid crystal, forming pixels by allowing light through. The front glass's color filter grants each pixel its color, creating a vivid image via the amalgamation of differently colored pixels.

OLED
OLED represents Organic Light Emitting Diode, revolutionizing display technology with its self-illuminating organic compounds.
Discover the marvel of light-emitting diodes (LEDs) with our advanced emissive electroluminescent layer. Crafted from a film of organic compounds, this cutting-edge layer radiates light as electric current flows through it. Exquisitely positioned between two electrodes, of which at least one flaunts transparency, this organic semiconductor marvels the world with its brilliance.


Uncover the intricate relationship between power consumption, lifetime, and brightness in OLED displays.
Power consumption in OLED displays is intricately linked to both the number of illuminated pixels and the panel's brightness. Fewer illuminated pixels and reduced brightness naturally lead to lower power usage. Unlike traditional LCDs that rely on backlighting, OLEDs boast substantially lower power consumption. Additionally, brightness inversely affects lifespan; dimmer displays enjoy a prolonged lifespan.


What makes OLEDs shine brighter than the rest?
OLED technology outshines LCDs with a dazzling array of advantages, including self-emission that eliminates the need for backlighting, an expansive viewing angle, ultra-lightweight design, and remarkably thin profile. It offers breathtaking contrast, rapid response times, and operates across a wide temperature spectrum, ensuring stability and resilience. Its excellent aseismatic capability, streamlined processing technology, and flexibility in display make it a preferred choice for cutting-edge applications.






What grants OLEDs their impressive ability to operate over a wide temperature range?
OLED luminescent materials, being in a solid state, display remarkable stability across diverse environmental temperatures. In contrast, liquid crystals are neither fully solid nor liquid, resulting in altered physical characteristics at extreme temperatures, which significantly affect display performance. OLEDs remain unaffected, providing consistent visual excellence.

How do OLED and LCD interfaces differ?
Seamlessly integrate OLED with applications, thanks to its I/O interface that mirrors that of an LCD. Supporting 8080/6800 series parallel interfaces, as well as SPI and I²C interfaces, OLEDs offer versatile connectivity that meets diverse application needs effortlessly.

How does OLED software differ from LCD software?
Software development for OLED and LCD displays shares fundamental similarities. Our expert FAEs are on standby, ready to provide comprehensive reference codes, ensuring a seamless process for your embedded software development.

What key considerations should be made in OLED structural design?
OLED structural design requires careful attention due to its composition of thin glass substrate and cap. To enhance product stability and aseismatic capability, it is crucial to integrate PCB designs, shock-proof elements, and structural orientation strategies to secure the OLED module effectively.

What is the right approach to adjust OLED display brightness?
Adjusting the brightness of an OLED display is both a technical and adaptable process. It can be achieved by finely tuning the OLED panel driving voltage and modifying the software code values. For detailed guidance, do not hesitate to reach out to our experienced FAEs.
