Problems solved by technology

In the existing display device testing technology, it directly outputs each test item and its item parameters to the screen for display, and after the test terminal recognizes the screen display image, the display data obtained after OCR recognition and Compared with the actual output data of the display device, this scheme is intuitive, but the shape and outline of the characters or numbers in the screen display image are not prominent enough to cause data recognition errors, and the reliability of the data recognition results is low, resulting in inaccurate test results. low rate

Embodiment Construction

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0048] see figure 1 , is a method flowchart of an embodiment of the data display method provided by the present invention.

[0049] In this embodiment, the data display method includes:

[0050] Step S1: Access the data to be displayed.

[0051] In this embodiment, when step S1 is executed, the data to be displayed can be but not limited to any kind of data that is input from the outside and can be displayed on the display device; the data to be displayed can also be the data of the display device itself Various technical performance parameters, such as when the display device is a liquid crystal display, its technical performance parameters include: viewing area, viewing angle, dot pitch (or stripe pitch), color degree, contrast value, brightness value, response time, etc. ....

Abstract

The invention discloses a data display method, which comprises the following steps of accessing data to be displayed; processing the data to be displayed, acquiring a character code of the data to be displayed, allocating a data display position for the character code of the data to be displayed on a display device screen; inquiring a color code table corresponding to the data display position, and acquiring a color code corresponding to the character code; and displaying color corresponding to the color code corresponding to the character code of the data to be displayed on the data display position corresponding to the character code of the data to be displayed. The data display method is low in complexity, and the data capacity of the screen output and display can be increased. The invention also discloses a test method of a display device. On the basis of the data display method, whether the data output of the display device is normal or not is tested, and the credibility and accuracy of the test are higher.

Description

technical field [0001] The invention relates to the technical field of data display and testing, in particular to a data display method and a display device testing method. Background technique [0002] At present, most display devices or display systems adopt character-based OSD (On Screen Display) technology, that is, on-screen display. The user can control the output of the menu frame bar on the display screen by pressing the Menu key, and set or adjust the multiple parameter information of the multiple adjustment items displayed on the menu frame bar according to actual needs. [0003] The technical core of the character-based OSD is to use the character generation chip to display the required characters on the display screen of the display device, so that they can be combined into characters or numbers that humans can recognize in the displayed image. For example, when the user operates the TV to change channels or adjust the volume and picture quality, the TV screen w...
