The global market for flat panel displays is presently dominated by TFT LCD. Due to its low price, clear colors, acceptable view angles, low power consumption, manufacturing-friendly design, slim physical structure, etc., it has forced CRT (Cathode-Ray Tube) VFD (Vacuum Fluorescent Display) out of the market and limited LED (Light Emitting Diode) displays to large display areas. TFT LCD displays have several uses, including in televisions, computer monitors, medical equipment, household appliances, cars, kiosks, point-of-sale (POS) terminals, low-end mobile phones, industrial meters, smart homes, portable devices, video gaming systems, projectors, consumer electronics, and advertisements. Visit our knowledge base for additional details about TFT screens.
There are several factors to take into account when selecting the best TFT LCD display module for your application. To see if you can find a good fit, please refer to the check list below.
It serves as the foundation for all projects. Outside dimension (width, height, and thickness) and AA (active area or pixel area) are the two dimensions to take into account. The typical product line of Kelai Display includes sizes from 1.0" to 32". With a size of 0.66", our OLED is suitable for wearable technology.
The clearance will be decided by resolution. Nobody enjoys seeing pixels on a monitor in full view. This is the cause of the increase in resolution from QVGA and VGA to HD, FHD, 4K, and 8K. However, better resolution also entails higher costs, power requirements, memory requirements, data transmission rates, etc. Kelai Display provides consumers with resolutions ranging from 128128 to HD, FHD, and 4K. Please refer to the Introduction for a complete list of possible resolutions. LCD Resolution
The orientation—landscape or portrait—must be taken into account. In addition, aspect ratio is crucial. In the past, you could have been OK with 4:3, but today you might be open to testing a bigger screen like 16:9 or even 21:9.
The choice of TFT screen brightness is crucial. By choosing a high brightness LCD that will only be used inside, you may avoid being disappointed by LCD image washout in strong light or letting the battery drain too quickly. The table below contains a set of general recommendations.
For our clients' convenience, Kelai Display offers standard brightness, medium brightness, high brightness, and high end sunlight readable IPS TFT LCD display products.
If money is tight, TN type TFT LCD can be used, however there is a choice of either 6 or 12 o'clock viewing angle. Gray scale inversion must be handled with caution. When purchasing a high-end device, you might spend more to choose an IPS TFT LCD that doesn't have the viewing angle problem.
Similar to the choice of viewing angle, TN type TFT LCDs have lesser contrast but lower cost, whereas IPS TFT LCDs have significantly better contrast but often cost more. Both options are provided by Kelai Display.
For the majority of applications, standard TFT LCD panels offer a wide enough temperature range. -20 to 70oC. However, in some (usually) outdoor applications, such as those involving temperatures between -30 and 80 °C or even higher, a specific liquid crystal solution must be employed. For an operational temperature requirement of -40oC, a heater is required. Most Kelai Display standard TFT displays can take temperatures between -40 and 85 °C, thus storage temperature is often not a problem. If you have any problems, feel free to contact our experts for more information.
In some handheld devices, power considerations might be crucial. The backlight often uses more power than other components of a TFT LCD display module. When not in use, backlight technology must be dimmed or completely turned off. Sleep mode or even employing memory on the controller must be taken into consideration during design for some extremely power-sensitive applications. Contact our engineers at any time with questions.
The interfaces that display or touch controller manufacturers offer are known as genetic interfaces. These interfaces include parallel, MCU, SPI (Serial Peripheral Interface), I2C, RGB (Red, Green, Blue), MIPI (Mobile Industry Processor Interface), LVDS (Low-Voltage Differential Signaling), eDP (Embedded DisplayPort), and others.
A significantly superior human machine interface that has gained widespread popularity is touch panels. Kelai Display has made significant investments to increase its ability to produce capacitive touch screen sensors. With a market share of over 18% in the global automobile industry, Kelai Display Factory is now the world's leading manufacturer of vehicle capacitive touch screens.Kelai Display can provide conventional RTP (Resistive Touch Panel) of 4-wire, 5-wire, and 8-wire.
