1236654 Amendment_Case No. 92115652_ ± V. Description of the Invention (1) The technical field to which the invention belongs The invention relates to a power-saving method for automatically turning off a display, and in particular, it relates to a method for automatically turning off a display according to user habits _ backlight Functional technology. Record and analyze the accumulated data of the last time the backlight function was used ^ Interval value, and use statistical principles to find the average backlight on time that is compatible with the user. Based on the average backlight on time, the backlight off function is performed. ^ Previous Tips 1 With the increasing development of the multimedia industry, digital electronic products such as phones, digital cameras, digital cameras, notebooks, and desktop computers (desk ο p) All are moving in the direction of more convenience, more functions, and more beautiful. Among them, the display can be said to be the most important output device in the above products, and various information in the products can be presented to the users through it. In the past, the cathode ray tube (Cathode Ray Tube 'CRT), also known as the image tube, was an important negative component in the display. Because of its good display quality and economic advantages, it has dominated the display market. However, if we consider the idea of green $$ L & source and the utilization of space [cathode =: = light, thin, short, small, low power consumption, etc. consumption js = law response, it cannot meet the times trend. Therefore, the display of emerging electronic products has become the mainstream in recent years. The liquid crystal display has the advantages of high picture f, medium = good performance, low power consumption, and no radiation. Liquid: Second, use efficiency

Case No. 1236654 Case No. 92115652 Amendment V. Description of the Invention (2) A display type used in bit-imaging technology is most common in notebook computer products. The principle of liquid crystal display design is simply to use two pieces of polar material, and inject liquid crystal material into them. When the current uses these two polar materials to pass through the liquid, the crystals at the corresponding positions will be combined to shield the light, thereby displaying the required daylight surface. In other words, the crystal in the liquid crystal display is like the shutter of a camera, which is used to determine whether light can pass through. Since the liquid crystal molecules themselves do not have a light-emitting property, a backlight board module (B a c k L i g h t MU d u 1 e) is usually required to be provided below the liquid crystal display. The backlight panel module provides the surface light source required for the LCD panel, so that the LCD panel can obtain sufficient brightness and contrast to achieve a high-quality display effect. The backlight module is roughly divided into two types: edge light type and direct type. Among them, the edge light type backlight plate module needs a light guide plate (Light Guide Plate) to convert the line light source into a display LCD panel. Surface light source, and the direct type backlight panel module can directly provide the surface light source required for the LCD panel without the need to configure a light guide plate. · In the color liquid crystal display, the driving types used can be classified into two types: passive driving type and active driving type. Take, for example, a thin film transistor (TFT) liquid crystal display with high daylight quality produced by an active driving method. The power consumed by its backlight module accounts for about the total power consumption. Therefore, the effect of reducing the power consumption of the thin-film transistor-type liquid crystal display backlight panel module needs to be increased in response to the reduction in power consumption of the thin film transistor type liquid crystal display. In other words, the thin film transistor-type liquid crystal displays a reduced power consumption ^

Description of the invention (3) To use the backlight panel to model the current backlight function time value of the enabler, start the event (such as the function. This type of function saves less time to turn off the function) The gap between the items cannot be closed or closed too late to cause the user to operate the invention. In view of this, the backlight of the display analyzes the user's basis. The off time of the learning dependency can reduce the user's power consumption, which is one of its advantages. Invented a method to improve the function. At the same time, one of the largest groups has been used to fix the timing. • Make the selection of the electric side impossible, make the power consumption LCD off time. The user method will choose to use the micro caller ’s The method of the present invention can be used according to the user's habit. Not only the manual operation needs to be increased, and the user's workload is reduced as the goal. The power saving method on the display is to use the display mode. If the user does not set a fixed value in advance, If any backlight function is turned on, the keyboard is turned on or the screen is touched) the disadvantages caused by turning off the backlight are as follows: The backlight is fixed and lacks flexible space, resulting in user needs. Because of the choice of the off time, the backlight function is turned off too quickly, so the backlight function needs to be manually turned on and off. Propose an automatic shutdown based on user habits. The backlight function driver records and divides this as the usage habit of the next time to turn off the backlight function. It automatically adjusts the backlight function and the flexibility of the backlight function to turn off time. It is also inconvenient. In addition to reducing the convenience of unnecessary electricity, the present invention also provides a method for automatically turning off the backlight of the display according to the user's habits. This method first presets a reference value when the backlight function is turned on on average, and a minimum reference value. Then, according to the time interval value of the last time the backlight function was used,

11269twf1.ptc Page 7 1236654 Case No. 92115652 Λ_η Revision V. Description of the invention (4) The relationship between the time interval value of the backlight function and the above maximum reference value and minimum reference value. The method is as follows: 1. When the time interval value of the last time the backlight function is used is greater than the maximum reference value or smaller than the minimum reference value, the time interval value of the last time the backlight function is used is regarded as invalid data; 2. When the time interval value of the last time the backlight function is used is between the maximum reference value and the minimum reference value, the time interval value of the last time the backlight function is used is regarded as a cumulative data, and the cumulative The data is recorded in a cumulative data sheet. Finally, according to the data in this cumulative data table, change the average on time of the previous backlight function and use it as the time basis for turning off the backlight function next time. In a preferred embodiment of the present invention, there are two cases where the time interval value of the last use of the backlight function is regarded as invalid data. One is when the time interval value of the last use of the backlight function is greater than the average of the preset backlight function. Turn on the time to add the sum of the first reference time; in addition, when the time interval value of the last use of the backlight function is less than the minimum reference value. When any of the above two situations occurs, the time interval value of the last time the backlight function was used is considered as invalid data, and it must be ignored. In addition, when the time interval value of the last time the backlight function is used is regarded as accumulated data, there are two different processing methods. If the time interval value of the last time the backlight function is used is greater than the minimum reference value and smaller than the preset backlight When the function average turn-on time, the time interval value of the last use of the backlight function is regarded as a cumulative data without change; In addition, if the time interval value of the last use of the backlight function is greater than the preset average turn-on time of the backlight function, and

11269twfl.ptc Page 8 1236654 Case No. 92115652 Amendment V. Description of the invention (5) In the cumulative data of a change that is less than the sum of the back time, there is no interval value and the cumulative value is the same as the time. Then the time is counted and accumulated. The function is turned on for reference. In order to make it easy to understand and explain, the implementer counts the change as data. The method to record the time between the technical materials is as follows: light power, the capital is accumulated, if it is one, the second mention, the first Based on the cumulative mean arithmetic and °, the above-mentioned special mention of the above can be considered as the average interval time plus the first reference time interval value of the last use of the backlight function. Either the cumulative data without change or the cumulative data must be recorded in the cumulative data table. The data is directly accumulated data of the last time the backlight function was used without any changes; if it is changed, it is necessary to record the sum of the reference time of the time interval of the last use of the backlight function and then record it in the accumulated data table. Yes, change the previously mentioned backlight function on average to preset a standard deviation and a third reference time. The accumulated data in the calculation data table is arithmetically averaged to get. At this time, the average turn-on time of the backlight function is equal to the average plus a multiple of the standard deviation, plus the third and last, and then the backlight function is calculated from the previously calculated backlight function to calculate the time to turn off the backlight function. The purpose, features, and advantages can better clarify the preferred embodiment, and in conjunction with the accompanying drawings, provide detailed implementation of the method embodiment of the present invention. Please refer to Figure 1 for a procedure to automatically turn off the backlight of the display according to user habits. It shows a preferred embodiment of the present invention. In this method, a backlight function is preset first

11269twfl.ptc Page 9 1236654 Case No. 92115652 Amendment V. Description of Invention (6) Average opening time and obtained). The acceptance value is divided into the largest one. The effective data is that the value and the accumulated value of the interval value are averaged in the data. Some assumptions: When one is on, it is more than the minimum two reference values. When the last minimum parameter is considered to be turned on for the material record, this needle and the upper back light will be implemented. The minimum and maximum back light will be used for the first time. Use one of the back-tested values to accumulate one by one. Use the function of the last time. Use the back function. Flat reference value. Reference value. Reference time. Backlight. Maximum backlight. Use each other. According to the use of the backlight, the reference value is based on the function relationship of the backlight function (if the backlight is used in the minimum backlight function (such as the time of step energy, it will be loaded (such as in the step data table as step S1 when the function of the backlight function) And a minimum reference such as step value and time interval. Interval value (time interval step S105) function time The value of the time interval between the evaluation of the two abilities is step S107); the interval value is between the time of using the backlight step S109), and is used as 11). The time interval interval value depends on the interval value, and it should change the value; and Step S1 03 The maximum parameter is set, the value is greater than the time in which it is regarded as a large reference time. The time interval value of this backlight power value as the accumulated data light function is invalid: Td All on time: T average ·· 5 seconds • T average +30 # interval: 30 seconds: the interval value of the 5 second function is greater than the average of the backlight function

11269twfl.ptc Page 10 1236654 _— Case No. 92115652_ Year Month and Revise __ V. Description of the invention (7) The sum of the opening time plus the first reference time, or the time interval between the last use of the backlight function is less than the minimum When one of the two conditions of the reference value occurs, the time interval value of the last use of the backlight function should be considered as invalid data (such as step s 10 7). It can be simply expressed as follows: If T d > T a v e r a g e + 30 seconds or T d < 5 seconds, T d will not be recorded. 0

T average + 30 seconds is the maximum reference value in this embodiment. This maximum reference value is the sum of the average on time of the backlight function plus the first reference time. The minimum reference value is set to 5 seconds. Although, in this embodiment, the first reference time is set to 30 seconds; the minimum test value is set to 5 seconds, but this need not be limited in actual implementation. Please refer to FIG. 2 for a flowchart of implementing the recording of accumulated data according to a preferred embodiment of the present invention. First, compare the time interval value of the last time the backlight function was used, the maximum reference value and the minimum reference value, and the average on time of the backlight function (such as step S 2 0 2). When the time interval value of the last use of the backlight function is greater than the minimum reference value and less than the average on time of the backlight function, the time interval value of the last use of the backlight function must be regarded as a cumulative data without change (eg step S204 ). It can be simply expressed as follows: If T average > Td > 5s, then Td = Td where T d = T d means that the accumulated data without change is the time interval value of the last time the backlight function was used, and no need Make any changes. When the time interval value of the last use of the backlight function is greater than the average on time of the backlight function, and less than the maximum reference value, that is, when the backlight function is on average

11269twfl.ptc 1236654

When the sum of the first reference time is added, the time interval value of the last time the backlight is used is a cumulative change of data (such as step 8206). The available table is not as follows: If T average + 30s > Td > T average, then Td = Td + 5s ί: all 7: two +5]: indicates that ㈣ change the accumulated data to this time interval when the old function was used last time The value is added to the second spring although, in this embodiment, the second reference time is set to 5, and the test: time /. There is no need to limit this to implementation. Regardless of the above, the accumulated data must be regarded as accumulated data. U =

What should be explained next is that the meter data is used to change the average brightness of the backlight function. Assume: f How to use the implementation details of the cumulative time in the cumulative data table to explain the standard deviation: S t Third reference time: 3 seconds The method is to first take these multiple cumulative data from the cumulative data table for arithmetic average. When the light function is turned on on average: the value; as a result, we can see that the early morning table is not as follows:

average = [(Tdl + Td2 + ～ + T29 + T3〇) / 3〇] + 2 S t + 3 seconds Its total accumulated data is set to 30; standard ^ ^: 3 2, but%

1236654 Case No. 92115652 Amendment V. Description of the invention (9) In actual implementation, the backlight function is turned on evenly. The backlight function is turned off. Because the present invention selects the effective cumulative accumulated data for the interim period, it is also fully applied. Since the user can choose in the past Less, the gap cannot be micro-closed, which instead causes problems. The present invention provides the user with the inconvenience of adjusting the backlight function to flexibly perform micro-operations. For the purpose of saving energy, although the present invention is limited to the present invention, within the scope of God and the scope, when the scope of protection is attached, it is not necessary to start time, without analysis of data and statistical settings. A habit, the closed tone of learning, is the limit of the other side. In addition, according to the above, the time to turn off the backlight function is calculated, and only the backlight efficiency of the method processing method is saved, and it is necessary to use the time to integrate the surface, and use the rounding. In principle. The function is turned off; the method of using the backlight to manually remove the backlight function is to reduce the user's unintentional and to account for these closed and closed optical power switches. Back to the injustice of the need to enter the light work, the energy of the backlight can be too short to use the light work, reducing the necessary and ineffective resources. The average recording style is a fast-close function for options. It can be closed and used less. The power of the material is only understood when the power is turned on. It may be too late or inconvenient to wait and analyze the time automatically. A preferred embodiment has been disclosed as above, but it is not used by any person skilled in the art, and some modifications and retouching can be made without departing from the essence of the present invention. Therefore, the scope of the application for patent protection of the present invention shall prevail.
