[0039] Reference Figure 1 and Figure 2 The display unit 2 may include a display 2P and a display driver 2D. When an electrical signal is applied to the display 2P, the display 2P can display a color. For example, the display driver 2D can apply an electrical signal to the display 2P.

[0040] The display measurement system 1 may include an input unit 410. The input unit 410 can receive input from a user, etc. The input unit 410 can generate a first signal S1 that includes information about the input.

[0041] The first signal S1 can be transmitted to the controller 420. For example, the first signal S1 may include information about the operation method of the display measuring device 10 and information about the operation method of the temperature control device 20. For example, the first signal S1 may include information about the setting of the eighth signal S8.

[0042] The display measurement system 1 may include a display measurement device 10. The display measurement device 10 may include a carrier 110.

[0043] The carrier 110 can mount the display 2P. The display 2P can be mounted on top of the carrier 110, for example. The carrier 110 can be moved or stopped.

[0044] The display measuring device 10 may include a color sensor 120. For example, the color sensor 120 may be located above the display 2P. For example, the color sensor 120 may measure the colors displayed on the display 2P.

[0045] Color sensor 120 can generate a second signal S2. For example, the second signal S2 may include information about the color displayed on display 2P. The second signal S2 can be transmitted to controller 420. The second signal S2 may be referred to as a "color information signal".

[0046] The display measuring device 10 may include a display temperature sensor 130. The display temperature sensor 130 can measure the temperature of the display 2P.

[0047] The display temperature sensor 130 can measure the temperature of the display 2P while it is mounted on the carrier 110. The display temperature sensor 130 can also measure the temperature of the display 2P without contacting it. For example, the display temperature sensor 130 can measure the temperature of the display 2P by measuring the infrared light emitted from it.

[0048] Multiple display temperature sensors 130 can be configured. For example, the display measuring device 10 may include multiple display temperature sensors 130.

[0049] The display temperature sensor 130 can generate a third signal S3. The third signal S3 can include information about the temperature of the display 2P. The third signal S3 can be transmitted to the controller 420. The third signal S3 can be referred to as the "display temperature information signal".

[0050] The display measurement system 1 may include a controller 420. The controller 420 can send and receive signals. The controller 420 can perform calculations.

[0051] For example, controller 420 can be implemented by at least one of a computer, processor, server, processing unit, circuit, and circuit board.

[0052] The controller 420 can process signals. For example, the controller 420 can generate output signals S6, S7 and S8 based on input signals S1, S2, S3, S4 and S5.

[0053] The input signals S1, S2, S3, S4 and S5 may include or indicate at least one of the first signal S1, the second signal S2, the third signal S3, the fourth signal S4 and the fifth signal S5.

[0054] Output signals S6, S7, and S8 may include or indicate at least one of the sixth signal S6, the seventh signal S7, and the eighth signal S8. Refrigerant information signals S4 and S5 may include or indicate at least one of the fourth signal S4 and the fifth signal S5.

[0055] The display measurement system 1 may include a temperature control device 20. The temperature control device 20 may include a refrigerant injection unit 200. The refrigerant injection unit 200 may inject refrigerant.

[0056] For example, the refrigerant injection unit 200 may be located above the carrier 110. For example, the refrigerant injection unit 200 may be located on the periphery of the display 2P mounted on the carrier 110.

[0057] The refrigerant injection unit 200 can cool the display 2P. For example, the refrigerant injection unit 200 can inject a refrigerant having a temperature lower than that of the display 2P. For example, the refrigerant injected by the refrigerant injection unit 200 may include at least one of air and an inert gas.

[0058] Temperature control device 20 may include refrigerant supply unit 300. Refrigerant supply unit 300 may supply refrigerant to refrigerant injection unit 200. For example, a pipe (not shown) may connect refrigerant supply unit 300 and refrigerant injection unit 200 and may be a flow path for refrigerant.

[0059] The refrigerant supply unit 300 may include a refrigerant temperature sensor 340. The refrigerant temperature sensor 340 can measure the temperature of the refrigerant supplied to the refrigerant injection unit 200.

[0060] The refrigerant temperature sensor 340 can generate a fourth signal S4. The fourth signal S4 can include information about the temperature of the refrigerant. The fourth signal S4 can be transmitted to the controller 420.

[0061] The refrigerant supply unit 300 may include a flow sensor 330. The flow sensor 330 can measure the hourly volume of refrigerant flowing into the refrigerant injection unit 200.

[0062] The flow sensor 330 can generate a fifth signal S5. The fifth signal S5 can include information about the volume of refrigerant flowing into the refrigerant injection unit 200 per hour. The fifth signal S5 can be transmitted to the controller 420.

[0063] The refrigerant supply unit 300 may include a cooling unit 320. For example, the cooling unit 320 can cool the refrigerant. The temperature of the refrigerant can be reduced by the cooling unit 320.

[0064] The cooling unit 320 can receive a sixth signal S6. The cooling unit 320 can operate in response to the sixth signal S6. The sixth signal S6 may include command information related to the operation of the cooling unit 320.

[0065] For example, the sixth signal S6 may include information related to the set temperature of the refrigerant to be cooled by the cooling unit 320. For example, the temperature of the refrigerant supplied to the refrigerant injection unit 200 may vary based on the sixth signal S6.

[0066] The refrigerant supply unit 300 may include a pump 310. The pump 310 may deliver refrigerant to the refrigerant injection unit 200. For example, the pump 310 may apply pressure to the refrigerant.

[0067] Pump 310 can receive a seventh signal S7. Pump 310 can operate in response to the seventh signal S7. The seventh signal S7 can include command information related to the operation of pump 310.

[0068] For example, the seventh signal S7 may include information related to the volume of refrigerant that will be delivered to the refrigerant injection unit 200 per hour via pump 310. For example, the volume of refrigerant that will be delivered to the refrigerant injection unit 200 per hour via pump 310 may vary based on the seventh signal S7.

[0069] For example, controller 420 can generate refrigerant output signals S6 and S7 based on refrigerant input signals S1, S3, S4, and S5. The refrigerant input signals S1, S3, S4, and S5 may include or indicate at least one of the first signal S1, the third signal S3, the fourth signal S4, and the fifth signal S5. The refrigerant output signals S6 and S7 may include or indicate at least one of the sixth signal S6 and the seventh signal S7.

[0070] The process by which the controller 420 generates refrigerant output signals S6 and S7 based on refrigerant input signals S1, S3, S4 and S5 can be a feedback control.

[0071] The controller 420 can transmit the eighth signal S8 to the display unit 2. For example, the eighth signal S8 can be transmitted to the display driver 2D. The eighth signal S8 may include command information related to driving the display 2P.

[0072] Display driver 2D can drive display 2P in response to the eighth signal S8. For example, the driving of display 2P can depend on the eighth signal S8. For example, the colors displayed by display 2P can depend on the eighth signal S8.

[0073] The color corresponding to the eighth signal S8 can be the color of the image displayed by the display unit 2 in response to the eighth signal S8 within the normal range.

[0074] The controller 420 can compare the color corresponding to the eighth signal S8 with the color extracted from the second signal S2. For example, the controller 420 can generate a "color difference". The color difference can be the difference between the color corresponding to the eighth signal S8 and the color extracted from the second signal S2.

[0075] For example, controller 420 can compare the color difference with a "reference color difference". For example, if the color difference is within the reference color difference, controller 420 can determine that display unit 2 is operating normally in response to the eighth signal S8.

[0076] For example, if the color difference exceeds the reference color difference, the controller 420 can determine that the display unit 2 is operating abnormally in response to the eighth signal S8. In this case, it may be necessary to correct the settings of the display driver 2D. The correction of the settings of the display driver 2D may depend on the color difference.

The hollow portion 242 may be connected to or communicate with the chamber 250. For example, the hollow portion 242 may be connected to or communicate with the inlet oral cavity 251.

[0122] Inlet rib 240N can be supplied from refrigerant supply unit 300 (see...) Figure 2The refrigerant is received. For example, the refrigerant can be introduced into the hollow rib portion 242. The refrigerant introduced into the hollow rib portion 242 can diffuse into the inlet chamber 251. The refrigerant introduced into the inlet chamber 251 can pass through the intermediate wall hole 232 and flow into the outlet chamber 252.

[0123] The aperture ratio of the intermediate wall 230 at a specific point on the intermediate wall 230 can be obtained by dividing the area of ​​the intermediate wall hole 232 formed in the differential region of the intermediate wall 230 at the specific point of the intermediate wall 230 by the area of ​​the differential region.

[0124] The opening ratio of the intermediate wall 230 can vary depending on the position of the intermediate wall 230. For example, the opening ratio of the intermediate wall 230 at a specific point can increase as the specific point of the intermediate wall 230 is positioned further away from the entrance rib 240N.

[0125] The inlet chamber 251 can receive gaseous refrigerant from the hollow rib portion 242. Therefore, the pressure in the inlet chamber 251 can increase as the inlet chamber 251 is positioned closer to the hollow rib portion 242.

[0126] The extent to which the refrigerant located in the inlet chamber 251 diffuses into the outlet chamber 252 can be positively correlated with the pressure in the inlet chamber 251.

[0127] The extent to which the refrigerant located in the inlet chamber 251 diffuses into the outlet chamber 252 and the opening ratio of the intermediate wall 230 can be negatively correlated.

[0128] The pressure in the inlet chamber 251 can decrease as the inlet chamber 251 moves further away from the inlet rib 240N. Since the opening ratio of the intermediate wall 230 at a certain point increases as the point moves further away from the inlet rib 240N, the degree to which the refrigerant in the inlet chamber 251 diffuses into the outlet chamber 252 can be more constant along the points of the intermediate wall 230.

[0129] For example, the size of the intermediate wall hole 232 can increase as the intermediate wall hole 232 is positioned further away from the inlet rib 240N. For example, the number density of the intermediate wall holes 232 at a specific point can increase as the specific point is positioned further away from the inlet rib 240N. For example, the product of the size and number density of the intermediate wall holes 232 at a specific point can increase as the specific point is positioned further away from the inlet rib 240N.

[0130] The extent to which the refrigerant diffuses from the inlet chamber 251 into the outlet chamber 252 needs to be constant along the intermediate wall 230. For example, since the extent to which the refrigerant diffuses from the inlet chamber 251 into the outlet chamber 252 is constant along the intermediate wall 230, the extent to which the refrigerant diffuses from the outlet chamber 252 to the outside can be more constant along the inner wall 210.

[0131] Since the extent to which the refrigerant diffuses from the outlet chamber 252 to the outside is constant along the point of the inner wall 210, the refrigerant injection unit 200 can make the display 2P (see...) Figure 1 More uniform cooling.

[0132] The pressure can be greatest in the portion of the inlet chamber 251 that is vertically located below the hollow rib portion 242. For example, the portion of the intermediate wall 230 that is vertically located below the hollow rib portion 242 may not include the intermediate wall hole 232. Therefore, it is possible to prevent relatively high-pressure refrigerant from flowing into the outlet chamber 252 in a non-diffusion state.

[0133] The intermediate wall body 231 can be formed into a plate shape. For example, the intermediate wall body 231 can form two surfaces. For example, the intermediate wall inlet surface of the intermediate wall body 231 can be one surface of the intermediate wall body 231. The intermediate wall outlet surface of the intermediate wall body 231 can be the other surface of the intermediate wall body 231.

[0134] The intermediate wall inlet surface of the intermediate wall body 231 can face the inlet outer wall 221. The intermediate wall inlet surface of the intermediate wall body 231 can be, for example, concave.

[0135] The outlet surface of the intermediate wall body 231 can face the outer outlet wall 222 and the inner wall 210. The outlet surface of the intermediate wall body 231 can be convex.

[0136] The inner surface of the inner wall 210 can be concave. The outer surface of the inner wall 210 can be convex. The direction in which the refrigerant is injected through the inner wall hole 212 can be the direction facing the outer surface of the area of ​​the inner wall 210 where the inner wall hole 212 is located.

[0137] Among the multiple inner wall holes 212, the upper inner wall hole 212U may be adjacent to the upper end of the inner wall 210. For example, the upper inner wall hole 212U may be located in the upper portion of the inner wall body 211.

[0138] The direction in which the refrigerant is injected from the inner wall through the upper hole 212U can be, for example, upward at 5° to 15°. For example, the direction in which the refrigerant is injected from the inner wall through the upper hole 212U can be, for example, upward at 10°.

[0139] Among the multiple inner wall holes 212, the lower inner wall hole 212L may be adjacent to the lower end of the inner wall 210. For example, the lower inner wall hole 212L may be located in the lower end portion of the inner wall body 211.

[0140] The direction in which the refrigerant is injected from the lower inner wall hole 212L can be, for example, downward at 80° to 90°. For example, the direction in which the refrigerant is injected from the lower inner wall hole 212L can be downward at 85°.

[0141] The refrigerant injected from multiple inner wall holes 212 can be distributed in the display 2P (see...). Figure 1 In the surrounding space of ). Through the shape of the inner wall 210 described above, the display 2P (see Figure 1 More uniform cooling.

[0142] The connecting rib 240C may include a rib body 241. The rib body 241 of the connecting rib 240C may be similar to the rib body 241 of the inlet rib 240N. For example, the rib body 241 of the connecting rib 240C may be substantially the same as the rib body 241 of the inlet rib 240N.

[0143] The connecting rib 240C may include a rib fastening portion 243. The rib fastening portion 243 may be formed in the rib body 241 of the connecting rib 240C. For example, the rib fastening portion 243 may be a hollow portion formed in the rib body 241 of the connecting rib 240C. For example, the rib fastening portion 243 may be separable from the chamber 250.

[0144] The rib fastening portion 243 can be coupled to an external device. For example, the rib fastening portion 243 can be fastened to a bolt. For example, the rib fastening portion 243 can be coupled to an external device by fastening it to a bolt.

[0145] Multiple inlet ribs 240N and multiple connecting ribs 240C can be arranged along the refrigerant injection unit 200.

[0146] For example, the same number of inlet ribs 240N can be arranged in each of the multiple refrigerant injection straight sections 200L. For example, one inlet rib 240N can be formed in one refrigerant injection straight section 200L.

[0147] For example, an inlet rib 240N can be located at the longitudinal center of a refrigerant injection straight section 200L. In other words, an inlet rib 240N can be located between the two ends of a refrigerant injection straight section 200L.

[0148] For example, the same number of connecting ribs 240C can be arranged in each of the multiple refrigerant injection straight sections 200L. For example, two connecting ribs 240C can be located in one refrigerant injection straight section 200L.

[0149] For example, two connecting ribs 240C may be located at corresponding ends of a refrigerant injection straight portion 200L. For example, two connecting ribs 240C may be located at corresponding ends of a refrigerant injection curved portion 200C.

[0150] Figure 8 It is cut along C1-C2. Figure 5 A cross-sectional perspective view of the refrigerant injection unit shown. Figure 9 It shows Figure 8 Part of the refrigerant injection unit shown.

[0151] Reference Figure 8 and Figure 9 The portions of chamber 250 corresponding to the multiple refrigerant injection straight portions 200L and the portions of chamber 250 corresponding to the multiple refrigerant injection curved portions 200C can be alternately connected and communicated with each other.

[0152] For example, the chamber 250 of the first refrigerant injection curved section 200C1 can connect the chamber 250 of the first refrigerant injection straight section 200L1 and the chamber 250 of the second refrigerant injection straight section 200L2.

[0153] For example, the chamber 250 of the second refrigerant injection curved section 200C2 can connect the chamber 250 of the second refrigerant injection straight section 200L2 and the chamber 250 of the third refrigerant injection straight section 200L3.

[0154] For example, the chamber 250 of the third refrigerant injection curved section 200C3 can connect the chamber 250 of the third refrigerant injection straight section 200L3 and the chamber 250 of the fourth refrigerant injection straight section 200L4.

[0155] For example, the chamber 250 of the fourth refrigerant injection curved section 200C4 can connect the chamber 250 of the fourth refrigerant injection straight section 200L4 and the chamber 250 of the first refrigerant injection straight section 200L1.

[0156] The oral cavity 251 can be accessed from the entrance rib 240N (see Figure 6 ) Receives refrigerant. For example, through inlet fin 240N (see Figure 6 The refrigerant introduced into the oral cavity chamber 251 can diffuse within the oral cavity chamber 251.

[0157] The refrigerant diffused in the inlet chamber 251 can pass through the intermediate wall hole 232 (see Figure 6 And it flows into the outlet chamber 252. The refrigerant flowing into the outlet chamber 252 can diffuse within the outlet chamber 252.

[0158] The refrigerant diffusing in the outlet chamber 252 can pass through the inner wall hole 212 (see... Figure 6 The refrigerant discharged to the outside of the refrigerant injection unit 200 can be located at display 2P (see...). Figure 1 In the upper space of ).

[0159] For example, the temperature of the refrigerant discharged to the outside of the refrigerant injection unit 200 can be lower than that of the display 2P (see [reference]). Figure 1 The temperature of the refrigerant injection unit 200 can therefore allow the display 2P (see) to reach a certain temperature. Figure 1 )cool down.

[0160] Reference Figures 1 to 9 The display 2P may generate heat during operation. The temperature of the display 2P may increase due to the heat generated from it.

[0161] For example, the temperature of monitor 2P may be higher than room temperature. For example, the temperature of monitor 2P may vary depending on the position of monitor 2P.

[0162] The display temperature sensor 130 can measure the temperature of the display 2P at each location on the display 2P. For example, the third signal S3 can include information about the temperature of the display 2P at each location on the display 2P.

[0163] For example, the temperature of the portion of display 2P adjacent to the first refrigerant injection line section 200L1 may be higher than the temperature of other portions. In this case, the characteristics of the refrigerant supplied to the first refrigerant injection line section 200L1 need to be different from the characteristics of the refrigerant supplied to the second to fourth refrigerant injection line sections 200L2, 200L3, and 200L4.

[0164] For example, the characteristics of the refrigerant supplied to the refrigerant injection line section 200L may include at least one of the refrigerant flow rate per hour and the refrigerant temperature. For example, a flow control valve (not shown) may be incorporated into each of the plurality of inlet fins 240N. The flow control valve (not shown) can control the flow rate of the refrigerant supplied to the inlet fins 240N.

[0165] For example, the hourly flow rate of refrigerant flowing into the first refrigerant injection line section 200L1 can be greater than the hourly flow rate of refrigerant flowing into each of the second to fourth refrigerant injection line sections 200L2, 200L3, and 200L4. Therefore, the display measurement system 1 can control the temperature of the display 2P in response to the temperature and temperature distribution of the display 2P.

[0166] Reference Figures 1 to 9 The inner wall 210 and the outer wall 220 can extend downwards from the upper end and to the lower end. For example, the upper end of the inner wall 210 can be connected to the upper end of the outer wall 220. For example, the lower end of the inner wall 210 can be connected to the lower end of the outer wall 220.

[0167] The inner wall 210 and the outer wall 220 can form the overall shape of the refrigerant injection unit 200. For example, the shape formed by the inner wall 210 and the outer wall 220 can be an annular shape.
