Problems solved by technology

Generally speaking, if you want to find out whether there is a problem with the display device or the signal source, you must use a dedicated test device, or you need to use other signal sources or display devices for cross-testing, which is very inconvenient for users.
For example, when there is a problem with the image displayed on the display device of the computer equipment in the user's home, since the user usually does not have a dedicated test device, and there is no redundant signal source or display device for cross-testing, it is difficult Determine whether the problem is the display device or the signal source, such as a display card, etc.

Embodiment Construction

[0026] The invention provides a display device and a testing method for the display device, which utilizes a test module to compare target signals corresponding to test samples with standard signal parameters, and generate and display test results. Therefore, the user only needs to use the display device to correctly test whether the output signal of the signal source is normal, and does not need other testing tools, which is very convenient for the user. Specific embodiments of the present invention will be described in detail below, so as to fully illustrate the features, spirit, advantages and simplicity of implementation of the present invention.

[0027] Please refer to Figure 1A , Figure 1A is a functional block diagram showing a display device 1 according to a specific embodiment of the present invention. In this embodiment, the display device 1 is connected to the signal source 3, and the display device 1 can be operated in the normal display mode and the input signa...

Abstract

The invention provides a display device and a testing method used for the same. The display device is connected to a signal source and can be operated under a normal display mode and an input signal testing mode. The display device comprises a display module and a testing module, wherein the display module can receive a plurality of input signals from the signal source and display the input signals; the testing module can receive a target signal in the input signals from the signal source; and the testing module can comprise a memory which is used for prestoring a standard signal parameter table which corresponds to a tested sample. When the signal source is operated to input the tested sample, and the display device is operated under the input signal testing mode, the testing module compares target signal parameters and the standard signal parameters and generates a testing result which is displayed by the display module.

Description

technical field [0001] The present invention relates to a display apparatus and a testing method for the display apparatus, and in particular to a display apparatus capable of testing an output signal of a signal source and a testing method. Background technique [0002] When there is a problem with the image displayed by the display device connected to the signal source, the problematic part may be the display device or the signal source connected to the display device. Generally speaking, if you want to find out whether there is a problem with the display device or the signal source, you must use a dedicated test device, or you need to use other signal sources or display devices for cross-testing, which is very inconvenient for users. For example, when there is a problem with the image displayed on the display device of the computer equipment in the user's home, since the user usually does not have a dedicated test device, and there is no redundant signal source or display...
