Abstract

A method for adjusting resolution of PC input signal is provided to execute automatic adjustment to only an initial PC input signal without using a PC automatic adjusting key separately by a user. A PC input resolution adjusting device comprises a scaler(10), a micro computer(20), a memory unit(30) and a display unit(40). The scaler receives a PC input signal from a PC input terminal, checks the resolution of the PC input signal in order to adjust the resolution of the PC input signal which is outputted to the display unit according to the resolution of the display unit. The micro computer reads the resolution data of the checked PC input signal in the scaler, and stores the resolution data in the memory unit. And the micro computer confirms whether the PC input signal is same to the resolution data stored in the memory unit, if so the micro computer outputs the PC input signal from the scaler to the display unit without executing the automatic adjustment. Otherwise, the micro computer executes the automatic adjustment by controlling the scaler, and stores the resolution of the PC input signal in the memory unit. The display unit outputs the PC input signal according to the adjusted resolution by the scaler.

The present invention relates to a TV, and more particularly, to a PC input resolution adjusting method for adjusting the resolution for a PC input signal.

In the case of PDPs, LCD TVs, or monitors, the resolution depends on the panel inch. There are also various formats for signals. Therefore, in order to optimally view the original signal without distortion, the resolution of the original signal and the TV or monitor should be the closest match.

For example, the resolution of the PDP 71 inch is 1920x1080, and the optimum signal is 1080I / P. The PDP 50 / 60-inch resolution is 1366 x 768 and the optimal signal is 720P. The optimum signal is 720P when the resolution of the PDP 42 inch is 1024x768, and the optimum signal is 480P when the resolution is 856x480.

At this time, every TV or monitor has an optimal resolution that it can best express. The resolution is automatically displayed without a remote controller or any key operation by communicating with the TV and other video devices.

In other words, most TVs with a PC input function have a function called auto PC adjustment, so that the resolution of the input signal is automatically adjusted and displayed so that the user does not need to adjust the resolution.

The purpose of performing this automatic PC adjustment is that even though the resolution is the same on the computer graphics card, the position and phase size of the graphics card may be slightly different. to be.

At this time, if the automatic adjustment is performed using the PC automatic adjustment function, the screen moves to the normal position.

By default, the graphics card used by the user is fixed, so if you adjust the resolution only once, you can rarely do it again later.

However, for the resolution called for the first time, it was troublesome to execute the automatic PC adjustment to enter the separate PC automatic adjustment item.

An object of the present invention is to provide a PC input resolution adjusting method in which a resolution is stored in a memory so that the resolution can be automatically adjusted unless the resolution is already stored in the memory.

Another object of the present invention is to provide convenience to a user by performing automatic adjustment on a PC input signal input for the first time without using a PC automatic adjustment key separately.

The present invention devised to achieve the above object is as follows. In the PC input automatic adjustment method of the present invention, after switching to the PC input mode, checking the resolution of the PC input signal input from the PC input terminal, determining whether the checked resolution information is the same as the resolution information previously stored in the memory unit; And if the checked resolution information and the resolution information stored in the memory unit are not the same, adjusting the resolution of the PC input signal.

And if the checked resolution information and the resolution information stored in the memory unit are not the same, storing the resolution information of the PC input signal in the memory unit.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a PC input resolution adjusting apparatus according to an embodiment of the present invention, Figure 2 is a flow chart of a PC input resolution adjusting method according to an embodiment of the present invention.

PC input resolution adjusting apparatus according to an embodiment of the present invention, as shown in Figure 1, comprises a scaler 10, a microcomputer 20, a memory unit 30, and a display unit 40.

First, the scaler 10 receives a PC input signal from a PC input terminal, checks the resolution of the PC input signal, and determines the resolution of the PC input signal output to the display unit 40 according to the resolution of the display unit 40. Adjust

The microcomputer 20 reads the resolution information of the PC input signal checked by the scaler 10 and stores the resolution information in the memory unit 30, while the input PC input signal is stored in the memory unit 30. It is determined whether the resolution information is the same, and if the resolution information is the same as the previously stored resolution information, the PC input signal is output from the scaler 10 to the display unit 40 without executing automatic adjustment.

On the other hand, if the resolution information already stored is not the same, the scaler 10 controls the automatic adjustment and stores the resolution of the new PC input signal in the memory unit 30.

The memory unit 30 stores the resolution information input from the microcomputer 20.

Finally, the display unit 40 outputs the PC input signal according to the resolution adjusted by the scaler 10.

An operation process of the PC input resolution adjusting device will be described in detail with reference to FIG.

First, when a user connects a PC input terminal to an external input terminal and selects an external input through a key input device such as a remote controller to switch to the PC input mode (S10), the scaler 10 is input through the PC input terminal. The resolution of the PC input signal is checked (S20).

When the scaler 10 checks the resolution of the PC input signal, the microcomputer 20 determines whether the resolution information is the same as the resolution information previously stored in the memory unit 30 (S30).

In this case, if the resolution information is the same as that stored in the memory unit 30, the PC input signal input through the scaler 10 is output to the display unit 40 without adjusting the resolution separately.

On the other hand, if the resolution information is not stored in the memory unit 30, the resolution of the PC input signal is automatically adjusted (S40) and displayed on the display 40.

For reference, in the embodiment of the present invention, the automatic adjustment of the resolution of the PC input signal may be easily performed by those skilled in the art, and thus the detailed description thereof will be omitted.

In addition, the resolution information not stored in the memory unit 30 is stored in the memory unit 30.

That is, in the method of automatically adjusting the PC input signal according to an exemplary embodiment of the present invention, when the resolution information stored in the memory unit 30 and the resolution information of the PC input signal are not the same, the user adjusts and outputs the resolution of the PC input signal. It is possible to conveniently view the PC input signal without having to execute automatic adjustment on the PC input signal arbitrarily.

The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea of the present invention.

According to the present invention configured as described above, the resolution is stored in the memory to automatically adjust the resolution if the resolution is already stored in the memory so that the user does not need to use a separate PC automatic adjustment key automatically adjusts only the first input PC input signal This can improve user convenience.
