[Prior Art] With the advancement of technology and the increasing standard of living of people, various intelligent electronic devices have gradually entered people's daily lives, such as laptop computers. A conventional notebook computer has a columnar protrusion on the display, and a trigger button is arranged on the main body. When the notebook computer is closed, the columnar protrusion contacts the trigger button, so that the system is in standby. mode. However, when the display is rotated to a range of 0 to 45 degrees from the main unit, the system of the notebook computer is generally not required to be used temporarily, and the system can be set to the standby mode. The traditional laptop can keep the system in standby mode when it is closed. It is still in normal power consumption when the display is rotated to 0~45° with the host, which is not conducive to saving energy. In addition, although it is possible to select the notebook in the standby mode of the notebook system option, it is inconvenient to operate the mouse or the like at this time. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a notebook computer capable of controlling a system in a standby mode during rotation of a display. A notebook computer includes a host and a display pivotally coupled to the host.

When the display is rotated to greater than 〇. The light emitter is formed with a reflective area on the keyboard area when it is less than 45°. The reflective area is provided with a plurality of light sensors electrically connected to the host circuit board, and the light sensors are used to receive the reflected light of the light emitters and convert the reflected light signals when the display forms a different angle with the host panel. For the current number of electrical signals. The host circuit board includes a comparison module and a control module, wherein the comparison module is pre-set with a standard electrical signal, and the comparison module is configured to compare the plurality of the current electrical signals one by one with a standard electrical signal; The control module is configured to provide a signal to the host circuit board and trigger the pen to be in the standby mode when the current electrical signal is greater than the standard electrical signal. Compared with the prior art, the notebook computer provided by the present invention senses the strength of the electrical signal converted by the reflected light of the display by the light emission 11 and the light sensor disposed on the host panel, and according to the The electric signal 'controls the host to switch from the normal working mode to the standby mode while the user rotates the display, thereby fully saving power and being convenient to operate. [Embodiment] Hereinafter, the present invention will be described in detail with reference to _. Referring to FIG. 1 , a notebook computer includes a host computer 10 and a host device connected to the host computer. The host panel 12 includes a host panel 12 facing the display 2G, and a host disposed in the host panel 12 Circuit board 14. The host panel 12 is overlaid on a keyboard area for inputting external information and an indicator area for indicating a caps switching state. The display (4) is provided with a columnar projection 22, the main surface form number 雠1 5th page/14 pages 0982051143-0 201109907 The board 12 is provided with a trigger key electrically connected to the host circuit board 14. 13. When the notebook computer 100 is closed, the main panel 12 and the display 20 are at zero. At the corner, the columnar projection 22 contacts the trigger key I3' to cause the notebook computer 100 to enter the standby state. The indicator area is provided with a light emitter 30 electrically coupled to the host circuit board 14 for emitting light of a particular wavelength toward the display 2 . In this embodiment, the light emitter 30 is fixed on the main panel 12 and emits parallel light, and the light emitted by the light emitter 30 is perpendicular to a plane where the host panel 12 is located. In order to increase the intensity of the reflection of the display 20, the display 20 is plated with a reflective film (not shown) to reflect light of a particular wavelength emitted by the light emitter 30. In the present embodiment, the light of the specific wavelength is infrared light. The reflective film is an infrared light reflecting film. When the display 20 is rotated to a range greater than 0° and less than 45°, the light emitter 30 forms a reflective area 12a on the keyboard area. [0010] The reflective area 12a is provided with a plurality of light sensors 40 electrically connected to the host circuit board 14, and the plurality of light sensors 40 are configured to receive the reflected light of the light emitters 30, and will display 2〇 The reflected light signals formed at different angles with the main panel 12 are converted into a plurality of current electrical signals one by one. In the present embodiment, the display 20 and the host panel 12 are at zero. At the corners, the parallel light emitted by the light emitter 30 is reflected directly from the display 20 back to the light emitter 30, and thus, the light sensor 40 cannot sense the parallel light emitted by the light emitter 30; when the display 20 45 is formed with the host panel 12. At the corner, the parallel light emitted by the light emitter 30 is reflected from the display 20 and then emitted parallel to the photo sensor 40. At this time, the photo sensor 40 cannot sense the parallel light emitted by the light emitter 30; When the display 20 is at an angle greater than 45° to the main panel 12, 098129797, Form No. A0101, Page 6/14, 0982051143-0, 201109907, the parallel light emitted by the light emitter 30 is obtuse with the outgoing light, and the emitted light cannot reach the reflective area 12a. The light sensor 40 is unable to sense the optical signal; when the display 20 is at an angle greater than 0° and less than 45° to the main panel 12, the parallel light emitted by the light emitter 30 must be partially reflected to the main panel 12 such that the light The sensor 40 generates a signal. Specifically, it is assumed that the display 20 is at an angle of 0 with the main panel 12, wherein 0° < θ < 45°, the horizontal distance between the light emitter 30 and the display 20 and the main panel 12 is L, and the reflective area 12a is far away. The edge of the light emitter 30 is X from the length of the light emitter 30. Then, according to the vertical distance between the light emitter 30 and the display 20 is (L*tan 0 ) and the incident angle of the light is 0 degrees, it is known that: [0011] X=L*tan Θ * tan2 θ [0012] = L* tan 0 *2tan 0 / ( tan2 0 +1 ) [0013] = L*n-1 / (tan2 0+l )] [0014] Therefore, as long as 0° < 0 < 45°, X can be taken image. It can be understood that in order to meet the size of the general notebook computer 100, the length of L is not too large. In the present embodiment, L is 3 cm. [0015] A photoelectric converter 41 is further integrated in the photo sensor 40, and the photoelectric converter 41 is configured to convert the optical signal sensed by the photo sensor 40 into the host circuit board 14. The plurality of current electrical signals. Specifically, when the display 20 and the main panel 12 are at an angle greater than 0° and less than 45°, since the light of the display 20 and the light emitter 30 are both irradiated onto the photo sensor 40, the photoelectric converter 41 is slightly strong. The electrical signal output; when the display 20 is at an angle of 45 or more with the main panel 12, since only the light of the display 20 is irradiated onto the photo sensor 40, the photoelectric converter 41 has a weak electric 098129797. Form No. A0101 Page 7 of 14 0982051143-0 201109907 Signal output. [〇〇16] In addition, a light barrier 30 is disposed between the light emitter 30 and the light sensor 40 to prevent the light emitted by the light emitter 3 from directly illuminating the light sensor 40. Caused a misjudgment of the signal. The host circuit board 14 further includes a comparison module 142 and a control module 144. [0018] A standard electrical signal is preset in the comparison module 142. Specifically, since the notebook computer 100 is turned on in the display state, the light emitted by the display will be irradiated to the reflective area 12a, and when the light emitted by the light emitter 30 reaches the reflective area 12a, the light sensor 4〇 The outgoing telegraph will be at least larger than the opto-electronic signal from the laptop. Therefore, the standard electrical signal should be greater than or equal to the electrical signal converted by the light emitted by the display 20 of the notebook computer 100, so that the optical sensor 40 can be greater than 〇. Less than 45. The standard Wei number is generated within the angular range. In the present embodiment, the standard electrical signal can be tested by the manufacturer during the process of the smashing, and the current electrical signal and the standard telephone ‘are all voltage signals. The comparison module 142 is configured to compare the plurality of current 胄 ◎ signals converted by the photoelectric converter 4 to the standard telecommunications, and output the ratio (4) to the control module 144. The reward control module 144 is configured to provide (4) a signal to the subtraction circuit board 14 when the current electrical signal is greater than the standard electrical signal, and trigger the entering standby mode by the control signal; when the current electrical signal is less than Or equal to the standard electrical signal, the control module 144 controls the notebook computer to be in a normal working mode. Specifically, the host circuit board 14 is provided with 098129797, form number A0101, page 8 / total 14 pages 0982051143-0 201109907, and has a standby mode switch (not shown) connected to the control module 14: 4, the control The module 144 outputs a control signal according to the comparison result of the comparison module 142 to control the standby mode switch to be turned on or off. When the standby mode switch is started, the notebook computer 1 enters the standby mode; When the standby mode switch is turned off and there are no other user commands, the notebook computer 100 maintains the normal operating mode. In the present embodiment, when the notebook computer 100 is closed, that is, when the main panel 12 and the display 20 are at an angle of 0°, the notebook computer 100 enters a standby state. [0020] When the notebook computer 10 is used, the user can rotate the display 20 with respect to the host panel 12 such that the light sensor 40 senses the display 12 in the reflective area 12a. The returned light is converted into the current electrical signal by the photoelectric converter 41. When the display 2 and the host panel 12 are greater than or equal to 45. At the angle, the current electrical signal is less than the standard electrical signal. The control module 144 controls the notebook computer 100 to be in a normal working mode; when the main panel 2 is rotated to be greater than 〇° and less than 45. When the current electrical signal is greater than or equal to the "standard electrical signal", the control module 144 controls the notebook computer 100 to switch the smart machine mode from the normal working mode. [0021] In addition, it is understood that when the light emitter 30 When the light source is a point light source, the center beam of the light emitted by the light emitter 30 is perpendicular to the surface of the host panel 12, and the comparison module 142 can recognize the surface according to the light intensity in the point light source. When the beam is reflected onto the photo sensor 4, the maximum signal of the generated optical signal is used to set the standard electrical signal. Moreover, in order to meet the needs of different users to select different down angles, a bevel may be disposed on the main panel 12, the bevel forming an acute angle α with respect to the main panel 12a, the 098129797 form number A〇l〇1 9 pages/total 14 pages 0982051143-0 201109907 The light emitter 30 is fixed on the inclined surface. At this time, the standby angle range of the notebook computer 100 can be expanded to be larger than 0° and smaller than (45 + σ) °. [0025] [0025] The notebook computer 100 provided by the present invention senses the display by the light emitter 30 and the plurality of light sensors 40 disposed on the host panel 12 The electrical signal converted by the reflected light is strong and weak, and according to the electrical signal, the notebook computer 100 is controlled to switch from the normal working mode to the standby mode while the user rotates the display 20, thereby fully saving power and being convenient to operate. .
