The world flat panel display market is currently dominated by TFT (Thin Film Transistor) LCD (Liquid Crystal Display). It has driven CRT (Cathode-Ray Tube) VFD (Vacuum Fluorescent Display) out of the market due to its low cost, sharp colors, acceptable view angles, low power consumption, manufacturing-friendly design, slim physical structure, and so on. TFT LCD displays are widely used in televisions, computer monitors, medical devices, appliances, automobiles, kiosks, POS terminals, low-end mobile phones, marine, aerospace, industrial meters, smart homes, handheld devices, video game systems, projectors, consumer electronic products, advertising, and so on. Please visit our knowledge base for more information on TFT displays.
There are numerous factors to consider when selecting the best TFT LCD module for your application. Please see the checklist below to see if you can find a good match.
It serves as the starting point for all projects. Outside dimension (width, height, and thickness) and AA (active area or pixel area) are the two dimensions to consider.
The clearance will be determined by the resolution. Nobody wants to see pixels on their screen. That is why resolutions have improved from QVGA to VGA to HD, FHD, 4K, and 8K. However, higher resolution comes at a higher cost in terms of cost, power consumption, memory size, data transfer speed, and so on.
The brightness of a TFT screen is critical. You don't want to be frustrated by LCD image washout in bright light, nor do you want to drain the battery too quickly by choosing a super-brightness LCD that will only be used indoors.
If money is tight, a TN-type TFT LCD can be chosen, but there is a viewing angle choice of 6 o'clock or 12 o'clock. Gray scale inversion must be removed with care. When designing a high-end product, you can pay a premium to select an IPS TFT LCD that does not have a viewing angle issue.
Similar to viewing angle selection, TN-type TFT LCD has lower contrast but lower cost, whereas IPS-type TFT LCD has much higher contrast but typically costs more.
Normal TFT LCD displays have a sufficiently wide temperature range for most applications. -20 to 70oC. However, in some (always) outdoor applications, such as -30 to 80oC or even lower, a special liquid crystal fluid must be used. The heater is required for an operating temperature of -40oC.
In some handheld devices, power considerations are critical. The backlight of a TFT LCD display module typically consumes more power than the rest of the display. When not in use, backlight technology must be dimmed or completely turned off. For some extremely power-sensitive applications, sleep mode or even memory on controller consideration must be incorporated into the design. Please contact our engineers for more information.
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 other interfaces are provided by display or touch controller manufacturers. Reshine Display has technologies that allow the above interface to be exchanged.
Reshine Display has technologies to create more advanced interfaces that are more convenient for non-display engineers, such as RS232, RS485, USB, VGA, HDMI, and so on. More information is available on our serious products. TFT modules, Arduino TFT display, Raspberry Pi TFT display, and a control board.
Touch panels are a much better human-machine interface that has grown in popularity. Reshine Display has made significant investments in capacitive touch screen sensor manufacturing capacity.
