[ first embodiment ] A method for manufacturing a semiconductor device
Referring to fig. 1, a flowchart of an air conditioner display control method according to a first embodiment of the present invention is shown. The air conditioner display control method comprises the following steps:
and step S10, receiving the wireless control signal transmitted by the wireless controller.

And step S20, obtaining a signal strength value, signal direction information and content to be displayed according to the wireless control signal.
Under the condition that the air conditioner and the remote controller are at different distances, the signal intensity of the wireless control signal received by the air conditioner is different; when the relative angles of the air conditioner and the remote controller are different, the signal source directions of the wireless control signals received by the air conditioner are also different; in addition, the air conditioner can obtain the content to be displayed according to the wireless control signal.
And step S30, obtaining display size information according to the signal intensity value.
Wherein the signal intensity value is related to a distance between the air conditioner and the remote controller, whereby an appropriate display size can be obtained according to the signal intensity value.
And step S40, obtaining display position information according to the signal direction information.

Referring to fig. 2, an embodiment of the present invention further provides an air conditioner. The air conditioner 10 has a wireless controller 11, a wireless array module 12, a display panel 13 and a controller (not shown).
Wherein, the wireless controller 11 is paired with the wireless array module 12 wirelessly. Referring to fig. 3, the wireless array module 12 includes, for example, 19 wireless receivers, and the 19 wireless receivers are arranged in a circumferentially spaced array. Specifically, the 19 wireless receivers are arranged at 180 ° around the circumference of the air conditioner 10, and one wireless receiver is arranged at an interval of 10 °.
For example, two of the 19 wireless receivers at opposite ends are in a horizontal straight line, and when one of the two wireless receivers is 0 ° and the other of the two wireless receivers is 180 °, the angles of the middle 17 wireless receivers are 10 °, 20 ° and up to 170 ° in sequence. The wireless controller 11 is, for example, an infrared controller, the wireless receiver is, for example, an infrared receiver, and the wireless array module 12 is an infrared array module.
The 19 wireless receivers are grouped to form a wireless array module 12. When the wireless controller 11 transmits a wireless control signal, a plurality of wireless receivers in the wireless array module 12 simultaneously receive the wireless control signal; however, since the plurality of wireless receivers have different deflection angles with respect to the wireless controller 11, the signal strength of the wireless control signal received by each of the wireless receivers is different, and the corresponding induced voltage is also different.
Wherein, the deviation angle between the wireless controller 11 and the air conditioner 10 and the distance between the wireless controller 11 and the air conditioner 10 are determined according to the wireless receiver which receives the wireless control signal with the maximum signal intensity.
According to the formula: d ═ β × K, the distance D between the wireless controller 11 and the air conditioner 10 can be calculated; wherein β is a signal strength-distance coefficient determined by a characteristic of the wireless receiver, and K is a signal strength value, i.e., an induced voltage value of the wireless receiver receiving the wireless control signal.
Wherein, the controller is electrically connected with the wireless array module 12 and the display panel 13; the controller obtains the wireless control signal received by the wireless array module 12, and the process of executing the air conditioner display control method is specifically as follows:
referring to fig. 4 and 5, the range of angles of the wireless array module 12 is 30-150 °; that is, the minimum value R of the angular range section of the wireless array module 12 is set to 30 °, and the maximum value R is set to 150 °. The display panel 13 has a size W × H.
Referring to fig. 6a, the user operates the wireless controller 11 to transmit a wireless control signal a to the air conditioner at a certain place; at this time, the wireless control signal a can be received by a plurality of wireless receivers in the wireless array module 12, but the signal strength value of the wireless control signal a received by each of the wireless receivers is different.
The plurality of wireless receivers respectively transmit the received wireless control signals a to the controller. The controller receives a plurality of wireless control signals a with different signal intensity values, and obtains the wireless control signal a with the maximum signal intensity value, namely the wireless control signal a with the maximum induced voltage value.
For example, the wireless control signal a is a temperature adjustment signal; the controller obtains the maximum signal intensity value K of the wireless control signal a received by the wireless receiver with the deflection angle of 20 °, and then the deflection angle value α between the wireless controller 11 and the air conditioner 10 is 20 °. In this case, the distance D between the user and the air conditioner can be calculated according to the formula D ═ β × K.
Calculating display size information B of the display content a according to the D and a formula B ═ (D/M) × A + E; wherein M is a preset distance value, for example, 5M, a is a character magnification factor, E is minimum display size information, and E includes, for example, a width and a height of the minimum display size; therefore, the width value w and the height value h of the B can be calculated according to the width value w and the height value h. When the distance between the user and the air conditioner is M, the display size information B is the largest; therefore, as long as D > M, the display size information B is a + E.
Since the deflection angle value α < 30 ° (minimum value r in the angle range section), the X coordinate in the obtained display position information is 0. The Y coordinate in the display position information is (H-H)/2 if the display content a is to be displayed centered on the display panel 13; if the display content a is to be displayed along the lower edge of the display panel 13, the Y-coordinate in the display position information is H-H. Wherein h is a height value in the display size information B.
At this time, the display content a may be displayed at (0, (H-H)/2) of the display panel 13 in accordance with the display size information B (w, H).
Referring to fig. 6b, the user operates the wireless controller 11 to transmit a wireless control signal b to the air conditioner at another place; likewise, the controller determines the wireless receiver that receives the wireless control signal b having the greatest signal strength in the same manner.
For example, the wireless control signal b is also a temperature adjusting signal; if the signal strength value K of the wireless control signal b received by the wireless receiver with the deflection angle of 90 ° is the maximum, the deflection angle α between the wireless controller 11 and the air conditioner 10 is 90 °. In this case, the distance D between the user and the air conditioner can be calculated according to the formula D ═ β × K.
Similarly, the display size information B of the display content B is calculated according to the formula D and the formula B ═ D/M × a + E, where B also includes the width value w and the height value h.
Since the deflection angle value is 30 ° ≦ α ≦ 150 ° (between the angle range interval R and R), the coordinate X in obtaining the display position information varies with the α, and the variation formula is X ═ a-R ≦ (W-W)/(R-R); while the coordinate Y is unchanged.
At this time, the display content B may be displayed at (X ═ W)/2, (H-H)/2) of the display panel 13 according to the display size information B (W, H).
Referring to fig. 6c, the user operates the wireless controller 11 to transmit a wireless control signal c to the air conditioner at a certain place; likewise, the controller determines the wireless receiver that receives the wireless control signal c having the greatest signal strength in the same manner.
For example, the wireless control signal c is also a temperature adjusting signal; if the signal strength value K of the wireless control signal c received by the wireless receiver with the deflection angle of 160 ° is the maximum, the deflection angle α between the wireless controller 11 and the air conditioner 10 is 160 °. In this case, the distance D between the user and the air conditioner can be calculated according to the formula D ═ β × K.
Similarly, the display size information B of the display content c is calculated according to the formula D and the formula B ═ D/M × a + E, where B also includes the width value w and the height value h.
Since the deflection angle value 150 ° < α (the maximum value R in the angle range section), the coordinate X in the display position information is obtained as W-W; while the Y coordinate is unchanged.
At this time, the display content c is displayed on the display panel 13 at (X ═ W-W, (H-H)/2) in accordance with the display size information B (W, H).
Of course, the air conditioner 10 further includes a voice broadcast device electrically connected to the controller, and in the scenes shown in fig. 6a and 6c, because the angle of the user is relatively biased, the controller further controls the voice broadcast device to broadcast the related audio. In addition, if the distance D between the wireless controller 11 and the air conditioner 10 is calculated to be greater than or equal to the preset distance value M, since the user is far away from the air conditioner, the controller also controls the voice broadcaster to play the related audio.
