It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention without any inventive step, are within the scope of protection of the invention.
Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The use of "first," "second," and similar terms in the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another.
Example one
As shown in fig. 1, it shows a touch control method provided by the present invention. The touch control method specifically comprises the following steps:
step 1: the OLED display module is used for self-luminous display of images;
step 2: collecting reflected light of the self-luminous light of the OLED display module in the step 1 through N reflected light collecting modules distributed in the OLED display module to obtain a reflected light intensity value;
and step 3: and comparing the reflected light intensity value with a contrast intensity threshold value to obtain the position of the contact.
The touch control method provided by the embodiment displays an image by self-luminescence of the OLED display module, and then obtains the reflected light intensity value of the self-luminescence of the OLED display module by the reflected light collection module, because the touch pen or the finger of the user for touch control can contact the OLED display module when the touch action exists, the self-luminescence of the OLED display module is obviously shielded and reflected, therefore, when the touch action exists and the touch action does not exist, the obtained reflected light intensity value is obviously different, therefore, the comparison between the reflected light intensity value and the contrast intensity threshold value can be used for accurately judging and obtaining the position of the contact, according to the touch control method, on one hand, the self-luminous property of the OLED display module is directly utilized to obtain the reflected light intensity value, so that the touch control precision can be effectively guaranteed, on the other hand, a touch layer does not need to be additionally arranged, and the light and thin design can be effectively realized when the touch control method is applied to a touch display module.
Specifically, in this embodiment, the reflected light intensity value includes N sub-intensity values, and each sub-intensity value corresponds to one reflected light collection module; the contrast intensity threshold comprises N sub-contrast values, each sub-contrast value corresponds to one reflected light collection module, and each sub-contrast value corresponds to one sub-intensity value. The step 3 comprises the following steps: step 3.1: sequentially and independently comparing each sub-intensity value and each sub-contrast value; step 3.2: when the sub-intensity value is larger than the sub-contrast value, acquiring the position information of the corresponding reflected light collection module; step 3.3: and acquiring the position of the contact according to the acquired position information of the reflected light collection module. In this embodiment, an independent comparison method is adopted to sequentially and independently compare each sub-intensity value and the sub-contrast value, so that when a contact occurs, the reflected light collection module corresponding to the contact collects a stronger sub-intensity value, and the comparison result is that the sub-intensity value is greater than the sub-contrast value, so as to obtain the position information of the corresponding reflected light collection module, and the position of the contact can be obtained according to the obtained position information of the reflected light collection module. Specifically, the contact positions that can be obtained according to the position information of the reflected light collection module can be determined according to the distribution density of the reflected light collection module, and when the distribution density of the reflected light collection module is high enough to cover each possible contact, the obtained position information of the reflected light collection module can be directly used as the obtained contact positions; when the distribution density of the reflection light collection modules is low, the touch position can be obtained by adopting a method of weighting and calculating a geometric center, for example, when three sub-intensity values are larger than the sub-contrast value, assuming that the sub-intensity values of the reflection light collection modules at the three positions of the point a, the point B and the point C are larger than the sub-contrast value and are all a times of the sub-contrast value, the touch position is the geometric center of a triangle formed by the three positions of the point a, the point B and the point C. Of course, when there is a large ratio of the sub-intensity value to the sub-contrast value of a certain point, the weight of the point is large, and the touch point position can be obtained through weighting calculation.
Specifically, in this embodiment, the method for obtaining the sub-contrast value includes: and calculating the intensity of the reflected light collected by the reflected light collection module in a non-touch state as a sub-contrast value according to the self-luminous display image of the OLED display module and the position information of the reflected light collection module. Considering that the display brightness of the relevant position is already determined after the OLED display module determines the display data of the self-luminous image, the reflected light intensity collected by the reflected light collection module in a non-touch state can be effectively determined as the sub-contrast value according to the self-luminous display image of the OLED display module and the position information of the reflected light collection module. Specifically, a sub-contrast value database can be preset, because the brightness of the OLED display module has a range of minimum brightness and maximum brightness, specifically, the brightness of the OLED display module can be graded, the display brightness of the OLED display module is improved step by step in advance, and meanwhile, the OLED display module is ensured to be in a non-touch state, the reflected light intensity values obtained by the N reflected light collecting modules are obtained one by one to serve as sub-contrast values, so that the sub-contrast database is formed, and when the OLED display module displays images by self-luminous display, the sub-contrast values can be obtained from the sub-contrast value database according to corresponding display brightness information.
Example two
The principle of this embodiment is the same as that of the previous embodiment, and the structure is similar, and the difference is only that: the N reflected light collection modules form a lattice arrangement of X rows X Y columns, and step 3 includes:
step 3.1: acquiring each sub-intensity value in each line by line to obtain a sub-intensity value set arranged in the same line and obtain X line intensity values; acquiring each sub-intensity value in each column by column to obtain sub-intensity value sets arranged in the same column to obtain Y column intensity values; acquiring each sub-contrast value in each row line by line to obtain a sub-contrast value set arranged in the same row to obtain X row contrast values; acquiring each sub-contrast value in each column row by row to obtain a sub-contrast value set arranged in the same column to obtain Y column contrast values; step 3.2: sequentially comparing each line intensity value with each line contrast value and/or sequentially comparing each column intensity value with each column contrast value; when the sub-intensity value is larger than the sub-contrast value, acquiring the position information of the corresponding reflected light collection module; step 3.3: and acquiring the position of the contact according to the acquired position information of the reflected light collection module.
Specifically, in this embodiment, N reflective light collection modules are arranged in a dot matrix of X Y columns in X rows, so that the sub-intensity value and the sub-contrast value of each row or each column can be obtained row by row, column by column, and X row intensity values, X row contrast values, Y column intensity values, and Y column contrast values are obtained; specifically, the row intensity values may be displayed in a waveform diagram manner, that is, when each sub-intensity value in the same row is acquired one by one, the waveform diagram is drawn according to the acquired each sub-intensity value, and similarly, the column intensity values, the row contrast values, and the column contrast values are also displayed in a waveform diagram manner. Through the comparison of the row intensity value and the row contrast value or the column intensity value and the column contrast value, the point with the mutation in the oscillogram can be quickly determined as the point with the sub-intensity value larger than the sub-contrast value, and further the position information of the corresponding reflected light collection module can be obtained and the position of the contact can be obtained; in addition, by comparing the row strength value with the row contrast value and the column strength value with the column contrast value, each obtained sub-strength value can be subjected to contrast verification in the comparison of the row strength value with the row contrast value and in the comparison of the column strength value with the column contrast value, so that the contrast precision and the interference resistance can be effectively improved, and the position information of the corresponding reflected light collection module can be more accurately obtained.

The touch control method provided by the embodiment displays an image by self-luminescence of the OLED display module, and then obtains the reflected light intensity value of the self-luminescence of the OLED display module by the reflected light collection module, because the touch pen or the user's hand contacts the OLED display module when there is a touch action, it is obvious that the self-luminescence of the OLED display module is shielded and reflected, therefore, when the touch action exists and the touch action does not exist, the obtained reflected light intensity value is obviously different, the touch control method can accurately judge and obtain the position of the contact point by comparing with the contrast intensity threshold value, on one hand, the touch control method can effectively ensure the precision of touch control because the self-luminous property of the OLED display module is directly utilized to obtain the reflected light intensity value, on the other hand, a touch layer is not required to be additionally arranged, and the light and thin design can be effectively realized when the touch control method is applied to a touch display module. Specifically, in order to obviously distinguish the reflected light intensity value from the contrast intensity threshold value, an antireflection film can be attached to or plated on the OLED display module, so that the reflected light intensity values are obviously different between the non-touch state and the touch state, and the touch control judgment is more accurate.
