Embodiment Construction

[0039] The following will describe in detail with reference to the accompanying drawings in conjunction with the embodiments, so as to further explain the technical features and advantages of the present invention.

[0040] Method flow chart of the present invention is as figure 1 As shown, a method for improving the display effect of a display screen is applied to a terminal device. The terminal device includes a light sensor, a main chip and a photosensitive IC, and includes the following steps:

[0041] a. Set multiple groups of display gamma values, and each group of gamma values ​​corresponds to the light intensity of an ambient light interval;

[0042] b. The light sensor senses the ambient light, obtains the light intensity, and transmits the light intensity to the photosensitive IC;

[0043] c. The photosensitive IC analyzes the ambient light intensity, obtains the hue value, brightness value and saturation value of the ambient light, and transmits it to the main chip...

Abstract

The invention discloses a method for improving a displaying effect of a display screen and a terminal device thereof. The terminal device comprises an optical sensor, a main chip and a photoreceptive integrated circuit (IC). The method includes the following steps: a, a plurality of groups of display screen gamma values are set, and each group of gamma values correspond to light intensity of one ambient light range; b, The optical sensor senses ambient light, obtains light intensity, and sends the light intensity to the photoreceptive IC; c, the photoreceptive IC analyzes the ambient light intensity, obtains a tone value, a brightness value and a saturation value of the ambient light, and sends the tone value, the brightness value and the saturation value of the ambient light to the main chip; and d, the main chip calls a preset display screen gamma value according to the ambient light and sends the gamma value to the display screen, and the display screen adjusts contrast ratio. Under different ambient lights, corresponding display screen gamma values are set to adjust the contrast ratio of display screen, and the purpose of improvement of the displaying effect of the display screen is achieved.

Description

technical field [0001] The present invention relates to a display technology of a display screen of a terminal device under different ambient light, in particular to a method for dynamically adjusting a gamma value (gamma value) to improve the display effect of a display screen and a terminal thereof. Background technique [0002] With the development of handheld devices, users have higher and higher requirements for smart terminal devices, and users have different needs in different scenarios. For example, the requirement for display effect under strong light (such as direct sunlight) is one of the most important items. The traditional solution to this problem is to increase the brightness of the backlight or start with the structural materials of the display screen. The disadvantages of this are the increase in power consumption of the whole machine and the continuous rise in the cost of the display screen. Both equipment manufacturers and users are unwilling to see the r...
