Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in itself. Thus, "module", "component" or "unit" may be used mixedly.
The gray scale of an LED (Light Emitting Diode) display screen is also called as color level or gray scale, and refers to the brightness of a single primary color LED lamp bead. No matter be monochromatic screen, double-color screen or full-color screen, want to show image and animation and all need modulate the luminous grey scale of every lamp pearl that constitutes the pixel, and the fine degree of modulation is higher, and it is higher to represent grey scale. For the LED display screen, the higher the gray level is, the richer the color is, the more gorgeous the color is, the better the display effect is, and the clearer and finer the picture is; otherwise, the display color is single, and the change is simple.
The gray level of the LED display screen is limited by the number of bits of devices such as a system and a chip and the size of transmission data volume, and the high gray level and the high refreshing have mutual restrictive property, the gray level of the LED display screen can only be 16 bits after nonlinear transformation generally, and under the technical level of the existing system and chip devices, the gray level of the LED display screen is difficult to continuously improve on the premise of not reducing performance indexes of other aspects of the display screen.
The invention discloses a method for realizing gray control of an LED display screen, which utilizes visual inertia of human eyes and utilizes a pulse width modulation method to realize gray control, namely, the width of a light pulse (namely, a duty ratio) is periodically changed, so that the repeated lighting period is short enough (namely, the refreshing frequency of the display screen is high enough), and the human eyes can not feel that a light-emitting pixel point shakes.
The gray scale is related to the bit width of the gray data, and assuming that the bit width of the gray data is Nbit, the display panel can express 2N gray scales, and at this time, the display panel has the gray scale expression capability of Nbit. The gray scale mainly depends on the digital-to-analog signal conversion bit number of the control system, and the video processing chip, the memory and the transmission system of the system also require corresponding bit numbers. At present, an 8-bit processing system is mainly adopted for the LED display screen, namely the gray scale of the LED display screen is 256 (8 power of 2). Non-linear transformations may also be used to achieve so-called 4096 gray levels or 16384 gray levels or higher in the gray space size in order to allow the display to conform to conventional data sources without loss of gray levels, for example 4096 levels is a non-linear transformation from an 8-bit source to a 12-bit space and 16384 levels is a non-linear transformation from an 8-bit source to a 16-bit space.

Meanwhile, the requirement of the user on the display effect is higher and higher, and the high gray level becomes an extremely important performance index and selling point of the display screen. On one hand, however, the gray scale of the LED display screen is generally only 16 bits after nonlinear conversion because of the limitation of the number of bits of devices such as a system and a chip and the size of transmission data volume; on the other hand, the realization of the gray scale number and the refreshing frequency are two mutually restricted relations, and the high refreshing rate of the display screen is usually ensured to mean that only lower gray scales can be obtained; also for indoor small pitch products, high gray scales are more difficult to achieve because the reduction in brightness inevitably results in loss of gray scale.
