Antistatic display system and method

The present invention relates to an antistatic display system and method.

With the visual needs of electronic products, more and more electronic products are now using displays for graphic and text display. However, since electronic products are very precise, they are easily affected by external electric fields and magnetic fields. In particular, the effect of static electricity on the display is very obvious. Characteristic parameters such as brightness, hue, saturation, and contrast of the display are stored in the register. Therefore, when the external static electricity is driven in, the data in the register is often confusing, resulting in abnormal display of the hue and brightness of the display, and sometimes even a black screen. However, the value of the register is set only once after power-on, and the value of the register will not be assigned again unless the user adjusts the display. Therefore, when the above situation occurs, the value in the register is always in a chaotic state, but the user cannot adjust to the normal state, so the display will always display abnormally. In order to display again, the display can only be turned off and the display is restarted. Very inconvenient.

In view of the above, it is necessary to provide an antistatic display system and method that prevents static electricity from causing an abnormality in a display image.

An antistatic display system includes a processor, a register, and a driver, the register for storing display characteristic data, and the driver reading display characteristic data from the register. The processor includes: a parameter setting module, configured to set display characteristic data of the register; Determining whether the time interval from the display characteristic data of the last setting register is greater than a specific time; resetting the modulo block, when the determining module determines that the time interval from the display characteristic data of the last setting register is greater than a specific time, The display characteristic data of the register is set to the last display characteristic data, which is smaller than the visual retention time of the human eye.

An antistatic display method for setting display characteristic data of a register to a previous display characteristic data at a specific time, the specific time being less than a visual persistence time of a human eye, the antistatic display method comprising the following steps: setting The display characteristic data of the register; determining whether the time interval of the display characteristic data from the last setting register is greater than a specific time; setting the register display characteristic data to the last setting when the time interval of the display characteristic data from the last setting register is greater than a specific time Display characteristic data.

Since the present invention repeatedly sets the display characteristic data of the register at intervals, the register value of the static electricity is disturbed at any time when the static electricity is driven, and the display is normally displayed because the display characteristic data of the register is set again. .

The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

Referring to FIGS. 1 and 2 , the antistatic display system 1 provided by the present invention includes a processor 10 , a register 20 , a driver 30 , and a display panel 40 .

The display panel 40 can employ a liquid crystal display or an organic light emitting display. In the embodiment, the display panel 40 uses a liquid crystal display.

The register 20 is used to temporarily store display characteristic data. The display characteristic data includes data such as hue, brightness, saturation, and contrast that control the display environment of the display panel 40. The driver 30 reads display characteristic data from the register 20, and the driver 30 controls the display environment of the display panel 40 based on the display characteristic data.

The processor 10 includes a parameter setting module 12, a determining module 13, and a resetting module 14.

The parameter setting module 12 is configured to set display characteristic data of the register 20. The driver 30 acquires display characteristic data set by the parameter setting module 12 for the register 20 from the register 20, and the driver 30 controls the display environment of the display panel 40 according to the display characteristic data.

The determining module 13 is configured to determine whether the time interval from the display characteristic data of the last setting register 20 is greater than a specific time. After the register 20 has performed the display characteristic data setting once, the judging module 13 judges whether the time interval of the display characteristic data from the last setting register 20 is greater than a specific time. The display characteristic data setting of the register 20 includes initialization for setting, user setting, and parameter setting module 12 for setting. In order to ensure that the display effect is not affected, the specific time should be less than the visual persistence time of the human eye, so that the change of the display panel 40 is not visible to the naked eye. In this embodiment, the specific time is less than 1/30 second.

The reset module 14 sets the display characteristic data of the register 20 to the previous display characteristic data when the judging module 13 judges that the time interval from the display characteristic data of the last setting register 20 is greater than a specific time.

In the present embodiment, a 2.7-inch liquid crystal display screen of AU Optronics model A027DN01 was tested using an electrostatic gun. When the liquid crystal display screen is not repeatedly set with the display characteristic data of the register at every specific time provided by the present invention, the discharge positive pressure resistance is 1.5 kV, and the negative pressure resistance is -2.5 kV. When the display characteristic data of the register is repeatedly set every other specific time provided by the present invention, the discharge positive pressure resistance can reach 5 kV, and the negative pressure resistance is 5 kV. Significantly improved display display anti-static performance.

Please refer to FIG. 3 , which is a flowchart of an antistatic display method provided by an embodiment of the present invention.

Step S110: setting display characteristic data of the register 20. In this embodiment, the parameter setting module 12 is configured to set display characteristic data of the register 20. The display characteristic data includes data such as hue, brightness, saturation, and contrast that control the display environment of the display panel 40.

Step S130: It is judged whether the time interval of the display characteristic data from the last setting register 20 is greater than a specific time. In this embodiment, the determining module 13 determines whether the time interval of the display characteristic data from the last setting register 20 is greater than a specific time. In order to ensure that the display effect is not affected, the specific time should be less than the visual persistence time of the human eye, so that the change of the display panel 40 is not visible to the naked eye. In this embodiment, the specific time is less than 1/30 second.

Step S140: When the display characteristic data time interval from the last setting register 20 is greater than a specific time, the display characteristic data of the register 20 is set to the display characteristic data set last time. In this embodiment, when the distance is up When the display characteristic data time interval of the setting register 20 is greater than a specific time, the resetting module 14 sets the display characteristic data of the register 20 to the last display characteristic data.

Since the present invention repeatedly sets the display characteristic data of the register at intervals, the register value caused by the static electricity is disordered at any time when the static electricity is driven, and the display is normally displayed because the display characteristic data of the register is set again. .

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention.
