Embodiment approach

[0137] As an embodiment of the present invention, the driving circuit is used to realize a display suitable for red dichromatic color blindness. Patients with red dichromatic color blindness cannot compare colors (ie, red) and green colors in the first range or the second range. Distinguish it, therefore, preferably, when H 0 In the first range or the second range, -40°≤ΔH≤-1°, -1<ΔS<0, wherein the first range is [315°, 360°], and the second range If it is [0°, 45°], the first range and the second range may be stored in the color determination module 200.

[0138] In order to further ensure the authenticity of the displayed image, preferably, when 15°0 When ≤45°, -39°≤ΔH≤-1°, -0.099≤ΔS≤-0.001, and H 0 The greater the ΔH, the greater the H 0 The larger the ΔS is;

[0139] When 315°≤H 0 0 The larger the ΔH, the smaller the H 0 The larger the value, the smaller the ΔS;

[0140] When 345°≤H 0 ≤360°, or 0°≤H 0 When ≤15°, ΔH=-40°, ΔS=-0.1.

[0141] As an embodiment of the present invention...

Abstract

The invention provides a display driving method, comprising: Stp1, acquiring the hue of each sub-pixel in an input image; Stp2, judging whether the sub-pixel to be calculated in the input image is a color that can be distinguished from a reference color by a dichromatic patient; Stp3, The hue of the sub-pixels of the output image is calculated according to the formula H1=H0+ΔH. When the sub-pixel to be calculated is a color that cannot be distinguished from the reference color by the dichromatic patient, ΔH≠0, so that the sub-pixel corresponding to the position of the sub-pixel to be calculated in the output image becomes the dichromatic patient A color that can be distinguished from the reference color; when the subpixel to be calculated is a color that a dichromatic patient can distinguish from the reference color, ΔH=0. The invention also provides a driving circuit and a display device. The driving method is suitable for displaying images that can be viewed by patients with dichromatic blindness.

Description

Technical field [0001] The present invention relates to a display device for people with color vision defects, and in particular, to a display driving method, a driving circuit for executing the display driving method, and a display device including the driving circuit. Background technique [0002] Color blindness is a common visual abnormality or lack of disease, usually referred to by genetic factors, manifested as lack of recognition of certain colors or inability to recognize colors. According to statistics, male color blindness accounts for about 8% of the male population, and female color blindness accounts for about 0.5% of the female population. Due to the lack of ability to change color of color blindness, it brings a lot of inconvenience to patients' work and life. [0003] There are three types of cone cells in the human retina. The ratios are L-cone cells sensitive to long wavelengths (535-575nm), M-cone cells sensitive to medium wavelengths (500-550nm) and short wave...
