Problems solved by technology

[0003] However, the mainstream display with switchable viewing angles on the market currently only has two viewing angles, wide and narrow. Under the narrow viewing angle, it cannot be selected and switched according to the change of viewing angle, and the anti-peeping effect is not good.

Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] The present invention firstly provides a three-angle display driver for driving a display panel. figure 1 It is a module of a three-view angle display driver according to an embodiment of the present invention Figure 1 . In the embodiment of a three-view angle display driver of the present invention, as figure 1 As shown, the three-angle display driver includes a front-end input module 11 , a timing control module 12 , a detection control module 13 and a display panel driver module 14 .

[0025] Wherein, the front-end input module 11 is used for providing a viewing angle control signal to select a wide viewing angle mode, a first narrow viewing angle sub mode or...

Abstract

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.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a three-view display driver and a display device. Background technique [0002] Liquid crystal display (liquid crystal display, LCD) has the advantages of good image quality, small size, light weight, low driving voltage, low power consumption, no radiation and relatively low manufacturing cost, and occupies a dominant position in the field of flat panel display. The current display devices are gradually developing in the direction of wide viewing angles. Whether it is a mobile terminal application, a desktop display or a notebook computer application, in addition to the demand for a wide viewing angle, in many occasions, the display device is also required to have a wide viewing angle and a narrow viewing angle. Switching function, many display manufacturers have also launched a lot of switchable viewing angle displays accordingly. [0003] However, the mainstream display with...
