The design of the Mini L backlight module includes the selection of the PCB board and the driver IC solution. In the above disassembly of the 65-inch Mini L TV backlight board, the cost of the PCB board + driver IC is nearly 60%, which is the link that should be paid attention to when rucing the cost of the backlight module.
The driver IC sends control signals and data
To the display panel in the form of electrical signals.
The driver IC consists of gate drivers and source drivers. It generates instructions through A/D/algorithm processing, and then finland number data transmits the information from the motherboard to each pixel, controlling the voltage to form an image. For Mini L backlight, the increase in the number of L chips in series leads to insufficient voltage provid by one chip, so the number of requir driver ICs increases significantly, which increases the cost proportion of the driver IC.
Driver ICs are mainly suppli by mainland
Chinese manufacturers, Taiwanese manufacturers and Korean manufacturers Link of the
Overall, the share of Chinese eshell baron mainland manufacturers still has great potential to increase. The leading companies in the TV driver IC market are Novatek Technology (20.9%) in Taiwan and LX Semicon (19.9%) in Korea. The share of leading Chinese mainland manufacturers is generally 6%-8%, with a total share of 19.3%.
The driver IC link basically switches Link of the
From PM control mode to AM control mode to achieve cost ruction
At present, there are two main driving modes: PM (passive matrix) and AM (active matrix). At present, PM solution is more widely central african leads us, but with the increase of partitions, there are problems such as wiring difficulties and too many ICs, making it difficult to balance cost and performance. AM solution for driving adopts integrat architecture, which can attach the driver IC and L chip to one side, and by using a single-layer substrate, it can ruce the use of PCB materials and achieve cost ruction.
