Four "drivers" disassembled to find out
Next we dismantle the back cover of Skyworth TV 50E780U to see the manufacturing process inside the TV. Skyworth TV 50E780U's internal layout, wiring, scientific and rational, clean and generous, which has a good effect on the suppression of EMI electromagnetic interference.
Look at the internal structure of Skyworth TV 50E780U, divided into four major blocks: power board, constant current board, signal processing board and screen body. The power strip is the heart of the TV and provides power to the screen body and signal processing board. This power supply supports 110V to 250V input from the mains, which can adapt to the grid conditions in different regions of the country, and then boost it to 400V through the PFC circuit. The PFC circuit mainly corrects the phase of the current and voltage, solves the mains interference, and improves the useful work. Then output 5V, 12V and 24V respectively to the signal processing board and constant current board. This section of the power conversion efficiency is high, can reach more than 85%, the standby power consumption is less than 0.5W, energy saving and environmental protection.
The constant current board boosts 24V to about 80V to drive the backlight of the screen body.
The image processing chip of the signal processing board adopts the MT7232CDJ chip + novatek's 72314 scheme of MTK Corporation in Taiwan of China, and has a built-in dual-core ARM Cortex-A9 900MHz CPU, which has high chip integration and powerful functions. With 1G of DDR3, the speed can reach 1.3G, 16GB of memory.
Let's take a look at the UD function module board of this TV. This module uses novatek's 72314 chip. It is understood that there are mainly two functions:
1.MEMC (Motion Estimation and Motion Compensation Technology): The principle is to use a dynamic video system, insert a frame of motion compensation frame between the traditional two-frame images, the ordinary flat-panel TV 50/60Hz refresh rate to 100/ 120Hz. In this way, the motion picture is clearer and smoother than the normal response effect, so as to achieve the effect of removing the afterimage of the previous frame image and improving the dynamic clarity, and reducing the image smear to the degree that the human eye cannot perceive. The motion picture looks smoother and there is no frustration, giving the consumer a good sense of experience.
2. Implementation of v-by-one's interface technology: The v-by-one interface was developed by THine and is now mainly used in large-screen displays. The biggest advantage of the v-by-one interface is its low data lines and high transfer rate, which can reach 3.2 Gbits; it can help reduce cabling, reduce EMI/EMC interference, and at the same time reduce PCB board size.
