Problems solved by technology

[0012] The technical problem to be solved by the present invention is: to overcome the shortcomings of the existing digital display screen that the scanning signal acts on the pixel for a short time and the image display brightness is low, and provide a digital display device and its scanning method, which increases the scanning signal acting on the pixel. point of time, thereby increasing the brightness of the image display

Embodiment Construction

[0033] Below according to accompanying drawing and embodiment the present invention will be described in further detail:

[0034] exist figure 1 In the circuit shown, if the line scanning circuit and the brightness control circuit do not output signals to the pixels point by point, but let all the line driving circuits output control signals to the pixels of a whole line at the same time, that is, there is no line scanning, it is conceivable that The time for the image signal to act on the pixel will be increased by thousands of times, which can not only improve the brightness and clarity of the image, but also reduce the flickering of the image screen.

[0035] Such as Figure 7 Shown is a schematic diagram of the working principle of the non-line scan display of the present invention, Figure 8 It is a schematic diagram of the working principle of sampling, storing and field scanning control of image signals and other related control signals. In order to improve the clari...

Abstract

The invention relates to a digital display device and a scan method thereof. The digital display device includes a field scan control circuit; multiple field scan drive circuits corresponding to each row of pixel points on a display screen; multiple row drive circuits corresponding to each pixel point on the display screen. The field scan control circuits are connected to each field scan drive circuit to control the each field scan control circuit to output signals. A switch type sampling storage is arranged at an input terminal of the image signals, each time delay line of the switch type sampling storage is correspondingly connected to a column of row drive circuits. After the time-delay and storage are carried out to the input image signals by each section of time-delay line, the whole row of image signals are input to each row drive circuit to control the each row drive circuit to lighten the whole row of pixel points selected by the field scan drive circuits. The invention increases time of scanning signal acted on pixel point so as to raise brightness of image displayed, and reduce flicker of image.

Description

technical field [0001] The invention relates to the technical field of digital display, in particular to a digital display device and a scanning method thereof used in display devices such as a display or a television. Background technique [0002] At present, the flat-panel displays we use, or digital displays, such as: PDP (plasma), LCD (liquid crystal), LCOS (liquid crystal silicon), DLP (digital light display processor), OLED (organic light-emitting diode), etc. are digital Display screen, the display method of these digital display screens is completely different from that of traditional CRT picture tubes. Digital display screens use dot matrix to display images. We call these dot matrix pixels. When the digital display screen displays an image, it scans each pixel on the display screen one by one to make it emit light in sequence to display the image. [0003] Because there are many pixels on the flat panel display screen, generally several million, in order to preven...
