[0020] A transparent OLED screen is communicatively connected to the RTD2735TD signal converter. The transparent OLED screen serves as a display unit, used to receive and display 16 Vbyone signals output from the RTD2735TD signal converter.

[0021] This invention comprises an RK3588 processor, an RTD2735TD signal converter, and a transparent OLED screen. The specific technology is as follows:

[0022] RK3588 Processor: As the system's main control unit, the RK3588 is responsible for processing input signals and generating HDMI signals. The RK3588 is a high-performance application processor with powerful video encoding and decoding capabilities, supporting 8K video decoding and 4K video encoding, making it ideal for high-end display devices. It integrates a high-performance 3D GPU and a 2D acceleration engine, providing excellent graphics rendering capabilities suitable for high-end games and complex 3D graphics applications. Furthermore, the RK3588 possesses powerful artificial intelligence computing capabilities, embedding a high-performance NPU that supports multiple computing modes and boasts a computing power of up to 6 TOPS, enabling efficient processing of complex deep learning models and neural network inference tasks.

[0023] The RTD2735TD signal converter receives HDMI signals from the RK3588 and converts them into 16 V-by-One signals. The RTD2735TD is a high-performance signal converter supporting 3DP + 2 HDMI inputs, and outputs supporting 32-lane V-by-One, 16-lane eDP (HBR2), and 8-lane eDP HBR3, capable of driving 8K / 4K 165Hz screens. The RTD2735TD uses 8B / 10B encoding, providing better compatibility with other high-speed serial interfaces such as PCIExpress and USB 3.0. Converting 8-bit data to 10-bit data effectively solves DC-DC imbalance issues.

[0024] Transparent OLED screens: As display units, they receive 16 Vbyone signals converted by the RTD2735TD for display. Transparent OLED screens possess unique transparency and excellent image quality, and are gradually emerging in various fields. Transparent OLED screens are mainly divided into two categories: commercial display type and industrial application type. Commercial display type transparent OLED screens are mainly used in commercial display scenarios such as shop windows and billboards, characterized by high transparency, vibrant colors, and wide viewing angles. Industrial application type transparent OLED screens are mainly used in automotive displays, building intelligence, and other fields, characterized by high stability, strong weather resistance, and customizability.

[0025] Driving Technology: This embodiment of the invention uses 16 Vby-One signals to drive the transparent OLED screen. This driving method has high efficiency and high stability, ensuring the stability and smoothness of the displayed image. The Vby-One signal transmission rule is that for each Clock (DCLK), the V-by-One interface has 8 pairs of differential pairs (lane0 to lane7) transmitting simultaneously, with each pair responsible for one pixel; a total of 8 pixels transmit data together. Each pair of differential pairs simultaneously serially transmits 4 bytes (32 bits in total, 40 bits in the V-by-One transmission protocol). The smallest unit of signal is a bit, and the data length of 1 bit is used to synthesize an eye diagram (1 UI = 0.3367ns = 336.7ps).
