Thickness of less than 20mm LCD TV panels have been displayed on the back light is divided into CCFL and white LED two categories

In the FPD International 2007, the thickness of the TV below 20mm ultra-thin LCD panel modules have been exhibited. According to thickness of order as follows: Samsung 10mm (40 inches 1920 x 1080 pixel products), Taiwan CPT (Chunghwa Picture Tubes CPT (14mm) 32 inches 1366 x 768 pixels PHILPS LCD LG products), South Korea (42 inches 19.8mm 1920 x 1080 pixel products), Taiwan (AU Optronics, AUO, AUO 20mm (32 inches) 1366 x 768 pixel products).

All of the above products are thinned by reducing the thickness of the backlight. The choice of backlight light source can be roughly divided into two types, namely, CCFL (cold cathode fluorescent tube) and LED.

Using CCFL panel, in terms of cost and luminous efficiency is currently highly practical. Mentioned above in the four companies, the use of CCFL backlight to achieve thin LG PHILPS LCD and AUO. AUO commentator said, because of cost factors, the company uses CCFL to achieve thin". Two companies are scheduled to put into operation in the near future. Among them, LG PHILPS LCD will be in the near future mass production supply (the company's commentator), AUO is scheduled to start in the 2008 quarter of second mass production. Back light are straight down type.

On the other hand, the use of LED to achieve thin Samsung Electronics and CPT. Compared with the above two companies using CCFL panels thinner. The two are white LED, the structure of the side light type. Samsung Electronics production time scheduled for 2008 (the company commentator). CPT indicates that production time has not been determined.
