The most common being TN, STN and FSTN. The LCD fluid twists the orientation of light passing through the glass causing the active pixels to darken. Each fluid offers unique characteristics to your LCD. These characteristics results in changes to the LCDs color, viewing angle, clarity and/or temperature range. The use of which fluid type you choose (TN, HTN, STN or FSTN) will affect the unit cost. TN fluid is less expensive than STN fluid. STN fluid is less expensive than FSTN fluid type. Below is a brief description on a few of the different LCD fluid types with images added to help add clarity.
TN lcd screen, is Twisted Nematic. In a quiescent state, display has a 90° twist in the alignment of the liquid crystal molecules at the transition between the surfaces of the two glass substrates.Polarizers attached to the outer surface of the substrates are oriented to allow light to pass through the display. When activated selectively by an electric field, the activated segments align to the field and no longer twist light passing through the display creating a contrast between on and off states.
HTN lcd screen, (High Twisted Nematic, highly twisted nematic) nematic liquid crystal molecules, HTN Screen has a higher twist (between that of TN & STN) giving it increased performance over TN LCD. The viewing angle is superior to TN and has improved contrast when multiplexing from 1/8 to 1/32 MUX. HTN has a slight yellow tint that looks good with high contrast segments. HTN has a lower cost than STN.
STN (Super Twisted Nematic) The structure of STN is similar to TN & HTN but with 180 to 270twist. The higher twist gives better contrast and viewing angle for highly multiplexed applications. A STN display normally has a yellow-green or grey background that is due to the optical effect called birefringence that changes the polarization to elliptical rather than linear polarization.
FSTN (Film+STN) lcd screen, in order to improve the background color problem of ordinary STN, a compensation film is added to the polarizer to eliminate dispersion and realize black-and-white display.

As a key channel for human-device interaction, lcd display interfaces are increasingly applied in various interactive scenarios. LCD screens, as core components of human-machine interaction, have permeated all aspects of our lives. Sinocrystal, a professional lcd display solution provider, is committed to delivering high-quality, reliable LCD display products to global clients. Below, we introduce Sinocrystal Technology Co.Ltd to help you better understand us.
Organic light-emitting diodes (OLEDs), as a new display technology, have numerous advantages such as being lightweight, flexible, offering wide viewing angles, and low power consumption. OLEDs are widely applicable in fields like display panels and lighting. In recent years, OLED technology has made significant progress, but challenges remain, such as device lifespan, efficiency, and stability. The transport rates of electrons and holes are key factors that affect OLED performance. This article
The GC9307, a TFT LCD driver with QVGA resolution, has gained widespread use among LCD module manufacturers since its launch. Sinocrystal are excited to share a series of practical insights we have gathered from using the GC9307 driver.
In the current field of electronic devices, the lcd display screen is a crucial part of human-machine interaction. However, traditional lcd display solutions often face structural design constraints, limiting their effectiveness in specific scenarios. Against this backdrop, UART lcd displays, which are easier to develop and do not require consideration of underlying display technology, are gradually emerging as the optimal solution to overcome these structural limitations.
