The pop-up panel 181 can be slidably coupled up and down within the panel guide groove 125. For example, the panel guide groove 125 can form a sliding groove 125a formed on the long side of both sides of the rectangular shape. The panel guide groove 125 is formed on the long side of both sides of the rectangular shape of the pop-up panel 181, And a sliding wing 181a coupled to the slider 125a.

The actuator 182 is connected to the pop-up panel 181 to operate to raise and lower the pop-up panel 181. In one example, the actuator 182 may include a hydraulic cylinder 1821 and a hydraulic pump 1822. In this case, the hydraulic cylinder 1821 and the hydraulic pump 1822 can be mounted on the rear protective panel 120, and the hydraulic cylinder 1821 can be mounted on the rear side of the hydraulic cylinder 1821 such that the axial direction of the hydraulic cylinder 1821 is parallel to the longitudinal direction of the panel guide groove 125 (1821) may be disposed under the panel guide groove (125). At this time, the piston rod 1821a of the hydraulic cylinder 1821 may be connected to the pop-up panel 181.

The flashing LED 183 is an LED that flickers one or more times to induce the gaze of the pedestrian. The flashing LED 183 may be mounted on one side of the pop-up panel 181. That is, the blinking LED 183 may be mounted on the pop-up panel 181 such that the direction of light emission is directed toward the display unit 110.

The flashing switch 184 is electrically connected to the flashing LED 183 to blink the flashing LED 183. The flashing switch 184 can be mounted in the panel guide groove 125. At this time, the flicker switch 184 is disposed so as to be separated from the pop-up panel 181 when the pop-up panel 181 is popped up when the pop-up panel 181 is normally popped up before the pop- To this end, the pop-up panel 181 may pop up to a height that can be spaced apart from the pop-up flicker switch 184. For example, the flicker switch 184 may be in the form of a push-button switch and maintains an OFF signal in the normal state of being depressed by the pop-up panel 181, and when the pop-up panel 181 is away from the flicker switch 184, And outputs an ON signal to turn off the flashing LED 183.

Here, the blinking LED 183 and the blinking switch 184 can receive power through the computer unit 150. [

Meanwhile, the PC integrated display device according to another embodiment of the present invention may include a controller 190 for operating the eye-guiding pop-up unit 180 at a predetermined period. The control unit 190 may be electrically connected to the computer unit 150 and inputs the operation cycle of the eye-guidance pop-up unit 180 to the CPU 152 of the computer unit 150, The operation signal of the visual-guidance pop-up unit 180 may be input to the control unit 190 according to the operation of the user. The control unit 190 may operate the eye-gazing pop-up unit 180 according to an operation signal input from the computer unit 150. [ For example, the control unit 190 operates the hydraulic pump 1822 of the line-of-sight guiding pop-up unit 180 so that the line of sight guiding pop-up unit 180 is moved upward and downward so that the piston rod 1821a of the hydraulic cylinder 1821 moves up and down. Lt; / RTI >

The PC integrated display device according to another embodiment of the present invention operates the eye-gazing pop-up unit 180 according to the operation cycle of the eye-guiding pop-up unit 180 input in advance in the computer unit 150, The gaze of the pedestrian around the scene where the PC-integrated display device of the PC is installed can be guided.

That is, in order to induce the gaze of the pedestrian, the computer unit 150 inputs an operation signal to the control unit 190 according to the operation cycle of the gaze guidance pop-up unit 180 input in advance, The hydraulic pump 1822 of the line-of-sight guiding pop-up unit 180 is operated in response to the signal and the hydraulic pressure is supplied to the hydraulic cylinder 1821 through the hydraulic pump 1822. The piston rod 1821a of the hydraulic cylinder 1821 And pops up the pop-up panel 181 connected to the piston rod 1821a toward the upper end of the rear protective panel 120 as shown in FIG.

When the pop-up panel 181 pops up, the pop-up panel 181 releases the pressing force of the flashing switch 184, whereby the flashing switch 184 can input an ON signal to the flashing LED 183, (183) may be flickered at least once. Thus, the gaze of the pedestrian can be guided.

The PC integrated display device according to another embodiment of the present invention includes the eye-guiding pop-up unit 180 for blinking light at least once to guide the gaze of the pedestrian, The number of times the contents are exposed to the pedestrian can be increased. That is, the media content reproduced by the display unit 110 may not be recognized by the pedestrian frequently. The light is flashed at least once through the visual-guidance pop-up unit 180 to induce the gaze of the pedestrian Accordingly, it is possible to increase the number of times that the pedestrian is exposed to the pedestrian through the media content reproduced in the display unit 110 by allowing the pedestrian to view the media content reproduced in the display unit 110. [ Accordingly, when the media content to be played on the display unit 110 is advertisement or promotion information, there is an advantage that advertisement or promotion effect can be increased.

In the meantime, on the outer surface of the PC mount part 130 of the PC integrated display device according to an embodiment of the present invention, a coating layer coated with the anti-fouling coating composition may be formed so as to effectively prevent and remove the adhesion of contaminants have. The antifouling coating composition contains boric acid and sodium carbonate in a molar ratio of 1: 0.01 to 1: 2, and the total content of boric acid and sodium carbonate is 1 to 10 wt% with respect to the total aqueous solution. In addition, sodium carbonate or calcium carbonate may be used as a material for improving the coating property of the coating layer, but sodium carbonate is preferably used. The molar ratio of boric acid to sodium carbonate is preferably 1: 0.01 to 1: 2. If the molar ratio is out of the above range, the coating property of the base material is lowered or the water absorption of the surface is increased after coating.

The boric acid and sodium carbonate are preferably used in an amount of 1 to 10% by weight in the aqueous solution of the composition. If the amount is less than 1% by weight, the coating property of the base material is deteriorated. It is easy to occur.

As a method of applying the composition for anti-fouling coating on a substrate, it is preferable to apply the coating composition by a spray method. The thickness of the final coated film on the substrate is preferably 500 to 2000 angstroms, and more preferably 1000 to 2000 angstroms. When the thickness of the coating film is less than 500 ANGSTROM, there is a problem that it deteriorates in the case of a high-temperature heat treatment. When the thickness is more than 2000 ANGSTROM, crystallization of a coated surface tends to occur.

In addition, the composition for antifouling coating can be prepared by adding 0.1 mol of boric acid and 0.05 mol of sodium carbonate to 1000 mL of distilled water and then stirring.

Meanwhile, the rear surface protection panel 120 of the PC integrated type display device according to an embodiment of the present invention may be made of a material such as a zinc-plated steel sheet or an aluminum material, and the surface of the rear surface protection panel 120 may be dust, A coating layer may be formed of a surface coating material of a metal material in order to prevent corrosion of the surface from a material or the like. The coating layer is composed of 60 wt% of alumina powder, 30 wt% of NH ₄ Cl, 2.5 wt% of zinc, 2.5 wt% of copper, 2.5 wt% of magnesium and 2.5 wt% of titanium.

The alumina powder is added for the purpose of sintering, entangling, fusion prevention, etc. when heated to a high temperature. When such an alumina powder is added in an amount of less than 60% by weight, the effect of sintering, entangling and fusion prevention is deteriorated. When the alumina powder exceeds 60% by weight, the above effect is not further improved, but the material cost is greatly increased. Therefore, it is preferable to add 60 wt% of the alumina powder.

The NH ₄ Cl reacts with steam, aluminum, zinc, copper, and magnesium to activate diffusion and penetration. This NH ₄ Cl is added in an amount of 30% by weight. When NH ₄ Cl is added in an amount of less than 30% by weight, the reaction with aluminum, zinc, copper and magnesium in a vapor state is not properly performed, thereby failing to activate diffusion and penetration. On the other hand, if NH ₄ Cl exceeds 30 wt%, the above-mentioned effect is not further improved, but the material cost is greatly increased. Therefore, it is preferable to add 30 wt% of NH ₄ Cl.

The zinc is compounded to prevent corrosion of the metal that is in contact with water and to be used for electrical applications. 2.5% by weight of this zinc is mixed. If the mixing ratio of zinc exceeds 2.5% by weight, corrosion of the metal which is in contact with water can not be properly prevented. On the other hand, when the mixing ratio of zinc exceeds 2.5% by weight, the above-mentioned effect is not further improved, but the material cost is greatly increased. Therefore, it is preferable that zinc is mixed at 2.5% by weight.

The copper is combined with the aluminum to increase the hardness and tensile strength of the metal. This copper is mixed at 2.5% by weight. If the mixing ratio of copper is less than 2.5 wt%, the hardness and tensile strength of the metal can not be properly increased when combined with aluminum. On the other hand, when the mixing ratio of copper exceeds 2.5% by weight, the above-mentioned effect is not further improved, but the material cost is greatly increased. Therefore, copper is preferably mixed at 2.5% by weight.

Since the pure metal of magnesium has a low structural strength, it is used in combination with the zinc and the like to improve the hardness, tensile strength and corrosion resistance of the metal. This magnesium is mixed at 2.5% by weight. When the mixing ratio of magnesium is less than 2.5% by weight, the hardness, the tensile strength and the corrosion resistance to the salt water of the metal are not greatly improved when they are combined with zinc and the like. On the other hand, when the mixing ratio of magnesium exceeds 2.5% by weight, the above-mentioned effect is not further improved, but the material cost is greatly increased. Therefore, it is preferable that magnesium is mixed with 2.5% by weight.

The titanium is a lightweight, hard and corrosion resistant transition metal element with a silver-white metallic luster. Because it has excellent corrosion resistance and specific gravity, it weighs only 60% of steel.
