Problems solved by technology
When the user wants to use an electronic display device that meets the standard A 1280×1024 to display a signal that meets the standard B 1080×768, there will be a problem that the signal cannot be displayed correctly
If the user ignores this problem and forcibly displays a signal with an unknown resolution on the electronic display device, the displayed image will be shifted or distorted, seriously affecting the signal display function of the electronic display device
[0004] For the aforementioned problem that the signal cannot be displayed correctly, the current solution is to display the signal at a simulated resolution approaching the unknown resolution.
This solution can only reduce the degree of offset or distortion of the display screen, but cannot display the signal correctly
In addition, in many cases, if the electronic display device cannot obtain or calculate a suitable simulation resolution, it will cause serious distortion of the display screen, such as the display screen appears completely black or disappears completely, so that the user cannot continue to operate and must Reboot or restart the system, causing inconvenience in use, or even causing loss of the system

Embodiment Construction
[0021] Please refer to figure 1 , figure 1 A flowchart showing the execution of the method disclosed in the present invention. In one embodiment, the present invention provides a method for displaying signals, which is suitable for an electronic display device and used for displaying signals input to the electronic display device.
[0022] Firstly, the resolution data of the signal is transmitted to the computer coupled to the electronic display device in a wired or wireless manner (step S100 ). The resolution data is obtained from the detection signal of the electronic display device, and may include horizontal frequency and vertical frequency. Next, check whether the resolution data exists in the first data table of the computer (step S102 ), and the first data table is used to record the resolution data and corresponding display data. When the resolution data exists in the first data table, the corresponding display data is sent to the electronic display device (step S10...

The invention relates to a method for displaying signal, to display input signal of electric display, wherein it comprises: first, transmitting the resolution data of input signal of electric display to one computer; then judging if said resolution data is in the first data list of computer, while the first data list records the resolution data and relative display data; when the resolution data is in the first data list, transmitting relative display data to the electric display; when the resolution data is not in the first data list, judging if the resolution data is in the second data list, while the second data list is stored outside the computer, to record the resolution data and relative display data; when the resolution data is in the second data list, transmitting relative display data to the electric display, to be stored in the first data list of computer.
Description
technical field [0001] The present invention relates to a method for displaying signals, in particular to a method for displaying signals in an electronic display device, which is used to display signals with unknown resolution data. Background technique [0002] With the advancement of signal processing technology, the applications of electronic display devices such as liquid crystal displays (LCDs) are becoming more and more diversified, and the situation that a single electronic display device must meet different specifications or resolutions also changes with time. increase. For example, an LCD suitable for a desktop computer (desktop) may have to be used to display signals suitable for a notebook computer (Notebook) LCD. [0003] For electronic display devices, since the probability of receiving signals with unknown resolution increases, the probability of displaying signals with unknown resolution also increases at the same time. For example, an electronic display de...
