Anti-peeping coded lock system based on visional confusion and anti-peeing unlocking method based on visional confusion

The invention discloses an anti-peeping coded lock system based on visional confusion. The anti-peeping coded lock system based on visional confusion comprises a storing module, a setting module, a generating module, a displaying unit, an inputting unit, an obtaining module, a judging module and an unlocking module. The invention further discloses an anti-peeping unlocking method based on visional confusion. The unlocking method based on visional confusion comprises the following steps that an initial password is preset; a user enters an unlocking interface through activation operation; based on each password icon, an icon group comprising the password icon and multiple confusing icons is generated, and then random arrangement is conducted; the user finds all the icon groups comprising all the password icons on the unlocking interface through the initial password and conducts human-machine interactive operations in sequence so that the corresponding icon groups can relate; according to the execution sequence of the human-machine interactive operations, the icon groups are rearranged, and an icon group result sequence is generated; whether the icon group result sequence is matched with the initial password or not is judged through the judging module; unlocking action is executed. By the adoption of the anti-peeping coded lock system based on visional confusion, through visional confusion, the peeping resistance and the safety of an electronic device are effectively improved.

Three-view display driver and display device

ActiveCN110503929AReduce production and procurement costsImprove picture qualityStatic indicating devicesControl signalPattern time
The invention provides a three-view display driver and a display device. The three-view display driver comprises a front-end input module, a sequential control module, a detection control module and adisplay panel driving module. The three-view display driver is used for driving the display panel; the detection control module outputs visual angle electrode voltage same as the common electrode voltage when a wide visual angle mode is selected, outputs visual angle electrode voltage different from the common electrode voltage when a first narrow visual angle sub-mode or a second narrow visual angle sub-mode is selected so as to reduce a visual angle according to selection of the visual angle control signal, and selects the second narrow-view sub-mode time to output a dark-state frame signalof the specified frame at a fixed time interval so as to insert the dark-state frame, thereby further narrowing the visual angle. The invention further provides a display device using the three-view-angle display driver. According to the scheme, the effect of switching along with the change of the viewing angle can be achieved while the wide viewing angle and the narrow viewing angle are controllable, the instant environmental requirements of users are met, and the peep-proof effect is excellent.

Color film substrate, manufacturing method thereof and display device

The invention discloses a color film substrate, a manufacturing method thereof and a display device, and belongs to the technical field of display. The method comprises the following steps: forming ablack matrix pattern and a first alignment pattern on a first surface of a transparent substrate; using a shading plate to shade the black matrix pattern, and forming a second alignment pattern on a second surface of the transparent substrate, so that the orthographic projection of the second alignment pattern on the transparent substrate and the orthographic projection of the first alignment pattern on the transparent substrate are staggered; and forming a grating structure on the second surface of the transparent substrate based on the second alignment pattern. The second alignment pattern and the grating structure to be formed subsequently are positioned in the same side of the transparent substrate; therefore, based on the second alignment pattern, the alignment precision between the mask plate for forming the grating structure and the transparent substrate can be improved, the precision of the grating structure formed on the second surface of the transparent substrate is further improved, and the peep-proof effect of the display device manufactured through the color film substrate is better.
