Abstract

The embodiment of the invention discloses a display and input device. The device comprises a display panel and a fingerprint sensing module, the display panel comprises a display array, and the fingerprint sensing module comprises a sensing array; the display array comprises a first display area and a second display area, the first display area comprises overlapped areas of orthographic projections of the sensing array and the fingerprint image on the display array, and the second display area comprises other areas except the overlapped areas; in the fingerprint sensing stage, the first display area serves as an area light source for illuminating a fingerprint, display pixels in the first display area have at least two data refreshing periods, the same color spectrum is emitted in each refreshing period, and different color spectrums are emitted in two adjacent refreshing periods; and in the fingerprint sensing stage, the sensing array and the display array are refreshed in a line-by-line or interlaced scanning mode, and orthographic projections of lines of the sensing array which is being scanned and lines of the display array which is being scanned on the display array are not crossed. The interference to the fingerprint image can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display and input device. Background technique [0002] With the expansion of the mobile terminal application market, more functions have been expanded in the display, which is integrated with the touch panel to realize touch and display functions, and further integrated with the fingerprint detector to realize the fingerprint recognition function. The fingerprint detector basically has a flat or flat structure, and the outer shape of the display panel is also a flat structure. In terms of structure, the two can cover or fit each other, or the two plane maps can cover or superimpose each other. [0003] However, the fingerprint detector and the display panel may be different in screen size, resolution, image refresh rate, frame rate or arrangement of pixels, and their combination may lead to mutual checks and balances in image output and acquisition, which will...
