Development Case of 5” LCD Display for Field Monitor
Eric and his LCDs, today we will talk about our star LCD, HL050T27-02,a sunlight readable LCD display

1. Product feature of HL050T27/HL050T32
This LCD display is a representative product of Hello Lighting's high-brightness, high-resolution and wide-color-gamut panel series! It is one of HL’s legacy/long-standing core products, with its original prototype developed back in 2016. It was fully independently developed by our team according to the requirements of our client SmallHD, without any reference design. Therefore, this product fully demonstrates HL’s full-set design and manufacturing capabilities from size selection to final product formation when developing new products.
2. Product performance Parameters
TheHL050T27is a 5.0 inch diagonal LTPS TFT-LCD display panel product from Shenzhen Hello Lighting Co., LTD(hereafter called HL), with an integral WLED backlight system, without backlight driver, Touch screen optional . It features an operating temperature range of -20 ~ 70°C , a storage temperature range of -30~ 85°C.
It's general features are summarized as the following:
-Size: 5inch LCD display
-WELD Backlight,High brightness: 2000nits
-Wide Color Gamut, DCI-P3 107%, sRGB
-Portrait type, 1080X1920,high resolution
-View Angle: IPS free
-Capacitive Touch with AR/AG surface treatment
-Ultra thin 2.75mm
3. The process of the development
Our journey with this product started with a inquiry: SmallHD was looking for a high-brightness, high-resolution 5-inch display to serve as an on-camera field monitor for outdoor use.
During the component selection phase, we opted for the 5-inch panel with the highest resolution available on the market at that time — 1080×1920. Although this native panel is configured for portrait orientation, the customer was able to enable landscape display via software adjustment, which aligned perfectly with their usage needs.
Following the selection phase, we completed full-customized development per the client’s requirements:
l Custom-designed the FPC interface and outline to perfectly match the customer’s mother board
l Developed an ultra-slim backlight module to fulfill the client’s strict form factor requirements
l Partnered with a leading LED manufacturer to jointly develop custom LED chips that deliver both high color gamut, high brightness and optimized energy efficiency
l Integrated touch functionality, and added premium processes including anti-glare (AG) coating and anti-reflection (AR) coating to further boost on-site display performance in bright outdoor environments.
l We have done a lot of work on color gamut adjustment during the development process to meet customer needs, including replacement and testing of polarizer materials and customization of unconventional LED phosphors. Attached below is the color test report provided by the Small HD engineer.



We believe that the product, polished with meticulous attention, will gain recognition in the high-end market! HL aim to do better LCD displays.
