HSD021GPW1-90000A-MX Overview
HSD021GPW1-90000A-MX supports display 122×250 with aspect ratio of 1:2 (W:H), whose pixels are arranged in Rectangle. It features active area of 23.668(W)×48.5(H) mm, outline size of 27.068(W)×61.9(H)×1.6(D) mm, with surface treament of Hard coating. As a TN, Normally White, Reflective LCM product, HSD021GPW1-90000A-MX can provides 190 cd/m² display brightness, 15:1 (Typ.) reflective contrast ratio, 60/60/30/30 (Typ.)(CR≥2) (L/R/U/D) viewing angle , and response time of 5 (Typ.)(Tr+Td) ms. Gray scale or the brightness of the sub-pixel is determined with a 1-bit gray scale signal for each dot, thus presenting a palette of Monochrome colors. This product adopted 6S1P WLED as it's backlight systerm which was placed as Front light type and have a working life time of 30K hours, external backlight driver is additionally needed. HSD021GPW1-90000A-MX utilizes 4-wire SPI as it's signal inputting systerm, which connected by 50 pins FPC with power supply voltage of 3.3V (Typ.). It's typical vertical frame rate (Fv) is 1Hz.

Reflective MIP Displays Application

To operate in low-light conditions, RLCDs need to be paired with an efficient front light solution such as the Youritech Front Light Panel.With improved optical coupling, collimation, and attenuation, our front light solution efficiently delivers more light exactly where you need it, and efficient LEDs can be used without experiencing typical issues with diffusion and material losses. Plus, as few as one low-power LED can be used in a front light instead of the five or more LEDs needed for alternative display light guides, making our solution the most efficient front light option available today.

It means your devices can stop relying on power-hungry backlights. By reinventing light guide and front light technology, we makes it possible to fully embrace the inherent power-saving features of RLCDs – from the brightest outdoor to the darkest indoor lighting environments.
