Abstract

A system for avoiding eye and bodily injury from using a display device comprises: a storage unit for storing a first program and a second program; a timer for respectively measuring corresponding running time of the programs; a counter for counting a continuous running count of the first program; a control unit for running the programs stored in the storage unit and outputting a control signal; an OSD (On Screen Display) component for receiving the control signal, and outputting OSD data such as a series of dynamic icons for reminding users to blink, and pattern data for reminding users to take exercises; and a display unit for receiving the OSD data to display the dynamic icons, and the pattern data to show a comfort display. A corresponding method is also provided.

Claims

1. A system for avoiding eye and bodily injury from using a display device, the system comprising a control unit, a storage unit, a timer, a counter, an on screen display (OSD) component, and a displaying unit, wherein:

the storage unit is for storing a first program and a second program;

the timer is for measuring a waiting time for running the first program, and further for respectively measuring corresponding running times of the first and second programs, wherein the waiting time is measured when the display device outputs video signals;

the counter is for counting a running count for successively running the first program;

the control unit is for running the first program and outputting control signals when the waiting time reaches a first preset threshold value, and for running the second program when the running count reaches a second preset threshold value and outputting control signals;

the OSD component is for receiving the control signals, and outputting OSD data; and

the display unit is for displaying the OSD data in a first and a second modes corresponding to the first and second programs.

2. The system according to claim 1, further comprising a keypad unit for sending control signals to the control unit in response to operations of users.

3. The system according to claim 1, wherein the first mode is displaying the OSD data as dynamic icons for reminding a user to relax his/her eyes.

4. The system according to claim 3, wherein the dynamic icons are a series of eye symbols comprising an eye blinking symbol, an eyeball rotation symbol, an eye closing symbol, and an eye opening symbol.

5. The system according to claim 3, wherein dynamics of the icons comprise moving upwards, downwards, leftwards or rightwards, zooming in or out gradually and changing illumination of the icons.

6. The system according to claim 1, wherein the first mode is finished when the running time of the first program has reached a third preset threshold value.

7. The system according to claim 1, wherein the second mode is a comfort display obtained by switched gradually from a normal mode of a screen of the display device to a faint mode.

8. The system according to claim 1, wherein the second mode is a dynamic icon.

9. The system according to claim 1, wherein the second mode is displayed when the running count of the first program has reached the second preset threshold value.

10. The system according to claim 1, wherein the second mode is finished when the running time of the second program has reached a fourth preset threshold value.

11. A method for avoiding eye and bodily injury from using a display device, comprising the steps of:

(a) presetting a value of an interval and a number;

(b) setting a waiting time for running a first program, a running time and a running count

of the first program, and a running time of a second program as “

0;

”

(c) measuring the waiting time;

(d) if the waiting time has reached a first preset threshold value of the interval, running the first program to display a series of dynamic icons for reminding a user to relax his/her eyes;

(e) after the first program has finished, increasing the running count once;

(f) if the running count has not reached a second preset threshold value of the number, going to step (c), otherwise, running the second program to display a mode for reminding the user to relax his/her body; and

(g) after the second program has finished, going back to step (b) if or as required.

12. The method according to claim 11, wherein in said step (d), the dynamic icons are one kind of a series of eye symbols comprising an eye blinking symbol, an eyeball rotation symbol, an eye closing symbol, or an eye opening symbol, and a series of pictures.

13. The method according to claim 12, wherein movement of the symbols and the pictures comprises moving upwards, downwards, leftwards or rightwards, or zooming in or out gradually.

14. The method according to claim 11, wherein in said step (d), illumination of said dynamic icons is changeable.

15. The method according to claim 11, wherein the dynamic icons disappear when the running time of the first program has reached a third preset threshold value.

16. The method according to claim 11, wherein in said step (f), the mode is a comfort display obtained by switched gradually from a normal mode of a screen of the display device to a faint mode.

17. The method according to claim 11, wherein in said step (f), the mode is set as a dynamic icon or changeable illumination.

18. The method according to claim 11, wherein the mode is finished when the running time of the second program has reached a fourth preset threshold value.

19. A method for avoiding ocular injury and bodily injury from long-termed use of a display device, comprising the steps of:

providing a first program running as a reminder of performing relief from said ocular injury;

providing a second program running as a reminder of performing relief from said bodily injury;

running said first program for a first duration after an operating time of said display device meets a preset value;

repeating said running of said first program; and

running automatically said second program for a second duration in case that said repeating of said running of said first program meets a preset condition.

20. The method according to claim 19, wherein said preset value, said first and second duration and said preset condition are manually settable via an on screen display (OSD) menu of said display device.
