[0018] RK3588 processor, the RK3588 processor is used to receive input signals and generate HDMI signals after processing;

[0019] RTD2735TD signal converter, the RTD2735TD signal converter is communicatively connected with the RK3588 processor, and is used for receiving the HDMI signal outputted from the RK3588 processor, and converting the HDMI signal into 16-channel Vbyone signals;

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

[0021] The embodiment of the present invention is composed of RK3588 processor, RTD2735TD signal converter and transparent OLED screen. The specific technology is as follows:

[0022] RK3588 processor: As the main control unit of the system, RK3588 is responsible for processing input signals and generating HDMI signals. RK3588 is a high-performance application processor with powerful video encoding and decoding capabilities, supporting 8K video decoding and 4K video encoding, and is very suitable for high-end display devices. It has built-in high-performance 3D GPU and 2D acceleration engine, which can provide excellent graphics rendering capabilities and is suitable for high-end games and complex 3D graphics applications. In addition, RK3588 also has powerful artificial intelligence computing capabilities, embedded with a high-performance NPU, supports multiple computing modes, and has a computing power of up to 6TOPS, which can efficiently process complex deep learning models and neural network reasoning tasks.

[0023] RTD2735TD signal converter: receives HDMI signals from RK3588 and converts them into 16-channel Vbyone signals. RTD2735TD is a high-performance signal converter that supports 3DP+2HDMI input, and outputs support 32-lane V-by-One, 16-lane eDP (HBR2) and 8-lane eDP HBR3, and can drive 8K / 4K165Hz screens. RTD2735TD uses 8B / 10B encoding, which is better compatible with other high-speed serials such as PCIExpress and USB3.0. Converting 8Bit data to 10Bit data can effectively solve DC balance.

[0024] Transparent OLED screen: As a display unit, it receives 16 Vbyone signals converted by RTD2735TD for display. Transparent OLED screens have unique transparency characteristics and excellent picture quality, and are gradually emerging in various fields. Transparent OLED screens are mainly divided into two categories: commercial display and industrial application. Commercial display transparent OLED screens are mainly used in commercial display scenes such as window displays and billboards. They are characterized by high transparency, bright colors and wide viewing angles. Industrial application transparent OLED screens are mainly used in vehicle-mounted displays, building intelligence and other fields. They are characterized by high stability, strong weather resistance and customization.

[0025] Driving technology: The embodiment of the present invention uses 16 Vbyone signals to drive the transparent OLED screen. This driving method has high efficiency and high stability, and can ensure the stability and smoothness of the displayed image. The Vbyone signal transmission rule is that for each Clock (DCLK), the V-by-One interface has 8 pairs of differential pairs (lane0~lane7) transmitting simultaneously, and each pair of differential pairs is responsible for one pixel; a total of 8 pixels transmit data together. Each pair of differential pairs simultaneously transmits 4 bytes in serial (a total of 32 bits, the V-by-One transmission protocol has 40 bits), the minimum unit of the signal is bit, and the data length of 1 bit synthesizes the eye diagram (1UI=0.3367ns=336.7ps), and the specific signal characteristics can be obtained through eye diagram testing.
