Generally TFT LCD LCD brightness, according to the specifications of different TFT panel parameters, TN and IPS transmittance main different, at present, the market LCD LCD brightness is basically in the 200cd/m²-450cd/m², with the modern people use LCD LCD LCD equipment than the previous application more and more to come, therefore, before the brightness has been unable to meet the current Product demand. The requirement of increasing the brightness of TFT is getting higher and higher, subject to the limitation of TFT panel process and cost consideration, the way to increase the brightness is the easiest to realize in the backlight component, which can reach 900cd/m²-1100cd/m², ICP DAS has a lot of successful and rich design and manufacturing experience in increasing the brightness to satisfy the customer's product brightness demand.
1. Backlighting
1.1 Increase the brightness of the LED: the use of higher brightness LED, according to the different brightness levels of the LED, the brightness increases, the color of the LED will change accordingly, as far as the brightness is concerned, about to increase the brightness of 3%.
1.2 Increase the number of LEDs to enhance the overall brightness output, and increase the number of different to greatly improve the 13% brightness.
1.3 Dual-chip LEDs increase brightness, which requires the use of more current at about 101 TP3T brightness.
2. Optimization of the backlighting process
2.1 Improve the design of optical materials of light guide plate, diffusion film and light-enhancing film in order to improve the efficiency of light utilization and increase the brightness by about 1-5%.
3. Improvement of TFT liquid crystal panel transmittance (limited by materials, basically unchangeable)
3.1 Improvement of TFT liquid crystal materials: Selection of liquid crystal materials with higher light transmittance.
3.2 Optimization of TFT liquid crystal arrangement: Reduction of light loss through more reasonable molecular arrangement and process design.

4. Brightening polarizers
4.1 Increasing the polarizer POL coated by 3M can theoretically increase the 20%-30% brightness approximately.
5. Brightening technology for backlight materials
5.1 Adding brightening film RP: By adding brightening film to reduce light loss and enhance the output brightness, theoretically it can increase the brightness of 5%-10%.
5.2 Reducing surface reflection: Use anti-reflective coating to reduce external light interference and improve the display effect.
5.3 Increase in ESR materials produced by 3M, approximately 3%-5%.
The above programs provide improvement measures at different levels from hardware to materials, which can be selected according to specific application scenarios and budgets. Improvements can be synthesized to achieve desired results based on actual needs and cost factors. It is worth noting that the actual effect of each method may vary depending on the specific product and technical conditions, so a thorough evaluation should be conducted before implementation. In addition, considering the service life of the display, it is not recommended to set the brightness too high.
