When a customer chooses a TFT LCD module, one of the deciding factors is usually cost. For the cost of each TFT LCD module, the material cost still accounts for the largest proportion. Many components, such as color filters, driver IC, backlight modules, and polarizers, determine the cost of TFT LCD modules. Although the glass substrate does not account for a high proportion of the cost, it is one of the important components that affects the overall product quality, affecting the resolution, light transmittance, weight, viewing angle and durability of the LCD display.
For example, choose TFT LCD module with touch function or TFT LCD module without touch function? If you need a touch screen, you need to focus your search on with or without a touch panel. Knowing your needs and product type will help narrow down your options.

What Affects The Cost Of A TFT LCD Module?
When it comes to choosing the right TFT LCD module for the price, you may come across a variety of options. There are a few things you need to consider when considering which options are important to you. Below are the factors that will affect the cost of the TFT LCD module you choose.
l Color Filter
Color filter is the highest cost part in the key components of the LCD screen. In the material cost structure of the TFT LCD panel, the role of the color filter is to use the filter to produce red, green, and blue light three original color light. The three different colors of light are mixed with different proportions to produce a variety of colors, making LCD display appear color.
l Glass Substrate
From the perspective of the production process of LCD display screen, forming a complete LCD panel structure requires two glass substrates to be used as the bottom glass substrate of array and the corresponding bottom plate of color filter respectively. Therefore, the supply objects of glass substrate manufacturers include panel manufacturers and color filter manufacturers.
l Backlight
Since the LCD display itself is a non -luminous display device, it must be used to achieve the display effect with the help of the backlight source. Therefore, the quality of the backlight performance will directly affect the display quality of the LCD display. The backlight board accounts for about 16% of the cost of TFT LCD panel materials, which is a very important component for the entire TFT LCD panel. Backlight boards are mainly used by light sources (including CCFL, light -emitting diode LED, etc.), optical membrane, reflective board, light guide plate, diffusion board (1 ~ 2 pieces), prism plates (1 ~ 2 pieces), outer frames, etc. The component is assembled. Among them, the optical membrane and the light guide board are the most important technologies and costs in the backlight module. Taking a 15 -inch backlight module as an example, the optical membrane accounts for about 37%and the light guide plate accounts for 17%; The main optical design and the fineness and the fineness are controlled on the design and manufacturing of the light guide board, so the design and manufacturing of the light guide board is very important.
l Polarizer
Polarizers are a optical material with selectivity with a selective light. It is to control the polarization direction of specific light waves, make the light pass or cover, and provide the necessary display characteristics. Because the liquid crystal itself does not have the control function that allows light and cover, it is necessary to use polarizers to achieve related functions. When the quality requirements of the LCD screen are getting higher and higher, the future goal of the polarization board is to maintain high partial bias. In the brightness, increase the light transmission of light. At present, the technical partial brightness and light transmission rate have reached the upper limit of development. Therefore, the composite technology of low reflection surface treatment, low -cost low reflection panels and optical compensation membranes will become the main topic of future development.
l Driver IC
Generally speaking, the product function design of the drive IC varies with different LCD application products. The drive IC applied to TFT LCD can generally be divided into source IC and gate IC, which are located on the x-axis and Y-axis of the panel respectively. Data input and different voltage values applied to each pixel in the form of matrix drive have completed the color tone control and generated the color imaging function.
