One of the reasons for replacing the LVDS used today is that the requirements for using existing technologies to improve performance and reduce costs have reached their limits. LVDS is used between the image processing IC and the clock control IC in notebook computers and TVs, or between the clock control IC and the driver circuit (Figure 2). Increasingly powerful functions, such as the need for three-dimensional (3D) display on TVs, high-speed "4x" image switching, and multi-bit colors for better color reproduction, but the cost needs to be minimized. Televisions emphasizing these characteristics are expected to appear in 2010-2011. Until now, these improvements on TV have been achieved by increasing the number of LVDS signal lines, but this method has reached its limit.

Has appeared. For example, to process 1 080p video data with 30-bit color (10 bits per color) and 240 frames per second (4 times display), 96 (48 pairs) LVDS signal lines will be required.

THine Electronics pointed out that because so many signal lines are needed, it will be very difficult to make a TV at a reasonable cost. As long as LVDS is used, 40 to 50-inch TVs can process 1 080p images in 30-bit colors (10 bits per color) and 240 frames per second. It is almost impossible to be cheap. Continued use of LVDS will cause three main problems. The first is the surge in the number of signal lines, which will increase cable costs. The more cables, the less space left in the case, and it becomes more difficult to make the display thinner.

Second, the increased number of signal lines will increase the number of pins for the transmitter IC, image processor, and transmitter circuit, and increase packaging costs.

Third, because LVDS requires a dedicated clock, higher data rates cause data and clock lines to shift, making long-distance data transmission more difficult. Therefore, it becomes more difficult to manufacture large screens and design. The dedicated clock line is also one of the sources of strong electromagnetic interference (Figure 3).

In notebook computers, there is a competitive trend toward more advanced display panel functions and thinner, and LVDS technology is gradually failing to meet the requirements of thinner and cheaper. PC manufacturers are demanding higher data transfer rates for each pair of signal lines to achieve a reduction in the total number of signal lines and through thinner casing openings.

Notebook computer and TV manufacturers have immediately noticed that new data transmission technologies can replace LVDS.
