A method for uniform brightness adjustment of a display

Abstract

The present invention provides a uniform brightness adjustment method of a display. The brightness signal of the display is obtained, and a signal input command is generated according to the brightness signal; based on a parabola-like generation mechanism, the signal input command is transmitted to the dimming A signal generator, and generate an adjustment signal according to the signal input instruction; wherein the adjustment signal includes a PWM signal or an I2C signal; transmit the adjustment signal to the backlight controller to determine the brightness value of the display; Obtain the rated voltage and rated current of the display, based on the pulse modulation method, and determine the limit brightness value of the display according to the rated voltage and rated current; wherein, the limit brightness value includes the highest brightness value and the lowest brightness value; contrast The luminance value and the limit luminance value of the display determine an adjusted luminance difference, and update the current luminance value according to the adjusted luminance difference.

Description

technical field [0001] The invention relates to the technical field of display brightness uniform adjustment, in particular to a display brightness uniform adjustment method. Background technique [0002] At present, the display screens on the market only have a few steps to a dozen steps in terms of brightness adjustment. Due to the limitation of technical difficulty, the minimum brightness is about 15 nits, and it is impossible to achieve lower nits adjustment. At present, there are actually many demands that can adjust the brightness of the screen to the lowest limit, but due to the complexity of the technology, there is no good implementation solution. For example, some mobile readers launch night mode, which only reduces the irritation to human eyes by adjusting the background color of the reader itself. Only in this reading environment, it looks softer, but it still becomes dazzling when you leave the reader. Solve the problem fundamentally. There are still many requ...

Problems solved by technology

It is used to solve the problem that for handheld devices and various terminal devices, such as mobile phones, tablet computers, notebook computers, etc., in the dark environment at night, the screen brightness is very dazzling even if it is adjusted to the lowest level, the high-contrast screen in this dark environment Light can cause great irritation and damage to the human eye, and at the same time affect the surrounding people. However, due to technical complexity and high development costs, there are currently no corresponding technical measures to solve this problem , based on this background, the present invention proposes an extreme display technology, which can adjust the screen brightness of handheld devices and mobile terminals to an extremely low level, so that in a dark environment, the content of the screen can still be seen clearly without disturbing the human eye Vision, while greatly reducing the stimulation and damage to the human eye, this technology can be widely used in various fields such as consumer fields, military industry, aviation, and outdoors
