specific Embodiment approach

[0021] Due to the difference between the screen shape of the TV and the E-character vision test form, if the E-character vision test form is directly displayed on a TV with a screen aspect ratio of 16:9, the screen size may not be enough. If the E-character array is arranged vertically and completely Show on the screen, just may not be able to reach the original size of special-purpose E character visual acuity test form, therefore, adopt the following mode to solve this problem in the embodiment of the present invention:

[0022] 1. Only display a line of E characters to be tested in the center of the screen;

[0023] 2. If scrolling display is adopted, scroll the E character array up and down, and finally fix a position so that the E character line to be tested is displayed in the center of the screen;

[0024] 3. When the 16:9 screen cannot completely display the E character array vertically, rotate the E character array 90 degrees clockwise or counterclockwise.

Abstract

The present invention provides a television set with the function of vision testing. The television set comprises an MCU, a vision testing control module, a remote-control receiving module and a display screen, wherein the remote-control receiving module is used for receiving remote-control codes of opening directions of vision testing characters transmitted by a remote controller, and transmitting the remote-control codes to the MCU; the MCU is used for analyzing the remote-control codes transmitted by the remote-control receiving module, judging whether the opening directions of the vision testing characters are correct according to analysis results, and indicating the vision testing control module to output test results; the vision testing control module is used for outputting the test results to the display screen; and the display screen is used for displaying the test results. The MCU also indicates the vision testing control module to move a mouse cursor to select the characters under test according to the test result.

Description

technical field [0001] The invention belongs to the technical field of TV function application, and in particular relates to a method for using a TV to test eyesight. Background technique [0002] Today's multimedia audio-visual entertainment content is becoming more and more abundant, and high-tech image processing technology makes TV pictures colorful, which deeply attracts countless people who like to watch TV programs and play video games.

[0003] However, if you do not pay attention to the relief of eye fatigue, if the eyes are in a state of fatigue for a long time, it will have an irreversible impact on vision. Especially for adolescents and children in the developing stage, due to heavy learning tasks or indulging in video games, many of them wear glasses early, and the myopia rate is becoming more and more unoptimistic. However, because the slight dec...
