Vbo signal port, control board and TV

Abstract

The application provides a VBO signal port, a control board and a TV set. In this application, the receiving end of the VBO signal port outputs a VBO signal pair, and each VBO signal pair includes a first signal line and a second signal line arranged in parallel with each other. A resistance module is arranged between the first signal line and the second signal line, and the resistance module is provided with a plurality of resistors that can adjust the resistance value. Different signal sources can adjust different matching resistances of the receiving end, improve the receiving ability of the receiving end, and improve the accuracy of the signal pair. Compatibility. In addition, when the eye diagram or signal quality on the display screen is found to be poor, adjust the resistance value of the resistor module to reduce the bit error rate, and write the adjusted table parameters into the storage medium. After the display panel is turned on, and according to the analysis As a result, the new table of the storage medium is updated, and the display quality of the display panel is improved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a VBO signal port, a control board and a television. Background technique [0002] V-By-One, VBO for short, is a digital interface standard technology for image information transmission. Because this technology can support up to 4.0Gbps high-speed signal transmission, and because its unique encoding method avoids the time lag between the data and the clock at the receiving end, VBO technology is widely used in the field of ultra-high-definition LCD TVs, making ultra-thin and ultra-narrow TVs become possible. [0003] During the transmission of the VBO signal, after the handshake between the Tcon board and the main board is successful, it enters the display communication sequence for the transmission of the VBO signal. In addition to the data signal, the VBO signal also includes a time control signal embedded in the data signal. However, for the VBO signal transmission in the di...

Problems solved by technology

[0005] The embodiment of the present application provides a VBO signal port, a control board, and a TV set, which can solve the problem that the timing control signal in the VBO signal in the prior art is unstable or exceeds the setting of the Tcon board, and then makes the Tcon board directly from the VBO signal. When the data signal and timing control signal are analyzed for display, the timing control signal embedded in the VBO signal is abnormal, especially the poor eye diagram effect, such as blurred screen, no image, and colorful spots. The quality of the eye diagram is mainly It is related to the input and output impedance matching, good impedance matching will get better eye diagram effect
