Abstract

(57) [Problem] To provide a dust-preventing liquid crystal protection filter made of plastic which can ensure a good visual field even when used for a long time without dust entering the liquid crystal screen. SOLUTION: A sponge (4) is attached to a liquid crystal protection filter on which a silk screen (2) is printed on the back of a plastic plate (1) and a hook-and-loop fastener (3) is put thereon, so that dust is deposited on the liquid crystal screen. Good visibility can be secured without entering.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an improvement of a liquid crystal protection filter having both functions of protecting a liquid crystal screen and preventing dust.

[0002]

[Prior art]

 Liquid crystal protection filters that attach a magic tape (3) on a transparent plastic plate (1) are already known, but conventional liquid crystal protection filters have dust from four corners when used for a long time. However, there is a problem that the surface becomes dirty and the field of view becomes opaque, and the practicality is impaired.

[0003]

[Problems to be solved by the invention]

 An object of the present invention is to solve the above-described problems and to provide a dust-preventing liquid crystal protection filter made of plastic which can ensure a good visual field even when used for a long time without dust entering the liquid crystal screen.

[0004]

[Means for Solving the Problems]

 The above problem is solved by a dust-preventing liquid crystal protection filter, which is characterized in that silk printing (2) is performed on a transparent plastic plate (1), and a magic tape (3) and a sponge (4) are attached thereon. You.

[0005]

[Embodiment of the invention]

 Hereinafter, the present invention will be described based on the illustrated embodiment. FIG. 1 is a vertical sectional side view showing an example of a plastic dust-preventing liquid crystal protective filter according to the present invention, and FIG. 2 is a rear view thereof. In FIG. 1, a transparent plastic plate (1) is silk-printed (2). Attach it to the LCD monitor (5) with Velcro (3), and attach the sponge (4) to prevent dust from entering. In FIG. 2, silk printing (2) is performed at four corners of a transparent plastic plate (1), and a magic tape (3) and a sponge (4) are attached thereon. The sponge morphology cannot be seen from the front due to silk printing (2). By attaching the sponge (4), a good visual field can be secured for a long period of time because dust does not enter from the four corners.

[0006]

[Effect of the invention]

 By attaching a sponge to the above position, the dust-preventing liquid crystal protection filter of the present invention does not get dust even when used for a long period of time, so that a good visual field can be secured.

 The present invention relates to an improvement of a liquid crystal protection filter having both functions of protecting a liquid crystal screen and preventing dust.

[0002]

[Prior art]

 Although a liquid crystal protection filter in which a hook-and-loop fastener (3) is attached to the back of a plastic plate (1) is already known, the conventional liquid crystal protection filter has dust entering from four directions when used for a long period of time, and the liquid crystal screen becomes invisible. There was a problem that the dirt and the visual field became opaque and the practicality was impaired.

[0003]

[Problems to be solved by the invention]

 An object of the present invention is to solve the above-described problems and to provide a dust-preventing liquid crystal protection filter made of plastic which can ensure a good visual field even when used for a long time without dust entering the liquid crystal screen.

[0004]

[Means for Solving the Problems]

 The above problem is solved by a dust-preventing liquid crystal protection filter, which is characterized in that silk printing (2) is performed on the back of a plastic plate (1), and a surface fastener (3) and a sponge (4) are provided thereon. .

[0005]

[Embodiment of the invention]

 Hereinafter, the present invention will be described based on the illustrated embodiment. FIG. 1 is a longitudinal sectional side view showing an example of a plastic dust prevention liquid crystal protection filter according to the present invention, and FIG. 2 is a rear view thereof. In FIG. 1, a plastic plate (1) is subjected to silk printing (2). Attach it to the LCD monitor (5) with the hook-and-loop fastener (3), and attach the sponge (4) to prevent dust from entering. In FIG. 2, silk printing (2) is performed on a plastic plate (1), and a hook-and-loop fastener (3) and a sponge (4) are attached thereon. Due to silk printing (2), the shape of the sponge cannot be seen from the front. By attaching the sponge (4), a good visual field can be secured for a long period of time because dust does not enter from four directions.

[0006]

[Effect of the invention]

 By attaching a sponge to the above position, the dust-preventing liquid crystal protection filter of the present invention does not get dust even when used for a long period of time, so that a good visual field can be secured.
