Problems solved by technology
[0003] However, for the traditional LVDS transmission method, since CLK is included, the clock signal transmitted is a high-frequency signal on the liquid crystal display, and the liquid crystal display needs to always transmit high-frequency signals when it is working normally. The work of the wireless module of the communication device is affected, in other words, the transmitted clock signal will interfere with the reception of the wireless signal
[0004] In addition, in the traditional LVDS transmission mode, the clock signal may be attenuated during the transmission process, or may be changed by external influences. In this way, the receiving end of the LCD will collect data according to the wrong clock signal, which will cause cause loss of display data

Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0021] The transmission method of display data in the present invention, such as figure 2 shown, including the following steps:
[0022] Step 201: TCON adjusts the clock frequency of its own crystal oscillator unit to match the signal of the display data output by the graphics card of the communication device;
[0023] like image 3 As shown, specifically, when the communication device is started and initialized, the graphics card transmits a clock signal to the TCON through the display data signal line, and the TCON adjusts the clock frequency of the crystal oscillator unit according to the collected clock signal, which is the same as the frequency of the collected clock signal ;exist image 3 Among them, LV0, LV1 and LV2 are display data signal lines, and LV0 is used to transmit clock signals to TCON, while LV1 and LV2 transmit blank signals;
[0024] ...

The invention discloses a transmission method for display data. The method comprises that a timer / counter control register (TCON) adjusts clock frequency of a crystal oscillator unit of the register, and the clock frequency is matched with a signal of the display data outputted by a display card of communication equipment; and when the signal of the display data is acquired, the TCON adopts a clock signal generated by the crystal oscillator unit to be used as a clock signal corresponding to the display data outputted by the display card. The invention also discloses a transmission device for the display data. By the method and the device, interference of the clock signal to a wireless signal can be reduced effectively, and integrity of receiving of the display data further can be guaranteed effectively.
Description
technical field [0001] The invention relates to signal transmission technology, in particular to a display data transmission method and device. Background technique [0002] At present, various portable communication devices such as mobile phones, notebooks, Global Positioning System (GPS, Global Positioning System), etc., all transmit data through wireless signals, and the signal transmission mode between the graphics card and the LCD display of these devices is generally low-voltage Differential signal (LVDS, Low-Voltage Differential Signaling) transmission method, such as figure 1 As shown, the LVDS transmission method usually includes a clock signal line (CLK) and a display data signal line; among them, the display data signal line includes: LV0, LV1 and LV2, and the receiving end of the liquid crystal display receives the clock signal of the graphics card and transmits data to the data line. The display signal is collected, and data analysis and other work are carried ...
