[0062] figure 2 The basic flowchart of a transmission signal interference optimization method provided in this embodiment, the transmission signal interference optimization method includes:

[0063] S201. Determine a reference plane.

[0064] In this step, the reference plane is the plane on which the circuit board is set, and the circuit board may be a PCB circuit board, a flexible PCB circuit board, a thin film circuit, and the like.

[0065] S202. Obtain a signal simulation result.

[0066] In this step, a transmission signal of a specific frequency is loaded on the antenna, and a signal simulation is performed on the transmission signal to obtain a signal simulation result of the transmission signal.

[0067] S203. Obtain a reference signal simulation result.

[0068] After the reference plane is determined, the simulation result of the reference signal located on the reference plane is intercepted from the simulation result of the signal.

[0088] This embodiment shows an example of the application of the present invention on smart phones. In current smart phones, with the emergence of full screens, the area occupied by the display area of ​​the front display screen of the mobile phone is getting higher and higher. The distance between the screen driver IC on the cable at the lower end of the display and the antenna at the bottom of the mobile phone is getting closer and closer. The function of the current liquid crystal element is similar to that of a capacitor. The display of the image requires a switching voltage to continuously operate the element, so the driver IC has a built-in DC / DCpumping circuit converter to generate the high and low level VGH, VGL, and common frequency of the element switch. Generally, it is 600K or 800KHz. Since the LCD driver IC contains an oscillator to generate various clock working signals when the screen is bright, the driver IC contains many nonlinear devices. When the antenna of...

Abstract

The embodiment of the invention discloses a transmission signal interference optimization method, a display module and a terminal. In order to solve the problems that the integration level of an existing intelligent electronic product becomes higher and higher, the position of a component generating signal interference becomes closer and closer to the position of a signal antenna, and interferencebecomes serious when the antenna transmits signals, the method comprises the steps of determining a setting plane of a circuit board as a reference plane; loading a transmitting signal with a specific frequency on the antenna, and performing signal simulation on the transmitting signal to obtain a signal simulation result of the transmitting signal; according to a reference signal simulation result, determining a target area with minimum transmission signal interference; setting an interference device on the target area. According to the transmitted signal interference optimization method, the target area with the minimum interference on the circuit board needing to be provided with the interference component is found out through signal simulation, and by arranging the interference component in the target area, the signal interference problem generated by the interference component in the signal transmitting process of the antenna is optimized.

Description

technical field [0001] The present invention relates to the field of communication technology, and more specifically, to a transmission signal interference optimization method, a display module and a terminal. Background technique [0002] The smartphone industry has developed to the present, and full-screen products have exploded. As the name suggests, the full screen means a larger screen-to-body ratio, which benefits from the latest packaging technology of LCD. Among them, Samsung Note8 adopts COF packaging technology. COF technology puts the chip on the glass backplane on the screen cable, so that it can be placed directly at the bottom of the screen, leaving 1.5mm more screen space than COG. The iPhoneX / XS series benefited from the unique COP packaging process of Samsung's flexible OLED, because the backplane is not glass, and the material used is actually the same as the cable. On the basis of COG, the backplane can be folded back directly, and the thickness is furthe...
